1 Introduction

In this vignette we’re going to explain in detail how to use functions of the aggregate family, namely:

aggregate_metadata
aggregate_values_by_key

1.1 How to install ISAnalytics

To install the package run the following code:

## For release version
if (!requireNamespace("BiocManager", quietly = TRUE)) {
      install.packages("BiocManager")
  }
BiocManager::install("ISAnalytics")

## For devel version
if (!requireNamespace("BiocManager", quietly = TRUE)) {
      install.packages("BiocManager")
  }
# The following initializes usage of Bioc devel
BiocManager::install(version = "devel")
BiocManager::install("ISAnalytics")

To install from GitHub:

# For release version
if (!require(devtools)) {
    install.packages("devtools")
}
devtools::install_github("calabrialab/ISAnalytics",
    ref = "RELEASE_3_12",
    dependencies = TRUE,
    build_vignettes = TRUE
)

## Safer option for vignette building issue
devtools::install_github("calabrialab/ISAnalytics",
    ref = "RELEASE_3_12"
)

# For devel version
if (!require(devtools)) {
    install.packages("devtools")
}
devtools::install_github("calabrialab/ISAnalytics",
    ref = "master",
    dependencies = TRUE,
    build_vignettes = TRUE
)

## Safer option for vignette building issue
devtools::install_github("calabrialab/ISAnalytics",
    ref = "master"
)

library(ISAnalytics)
#> Loading required package: magrittr

1.2 Setting options

ISAnalytics has a verbose option that allows some functions to print additional information to the console while they’re executing. To disable this feature do:

# DISABLE
options("ISAnalytics.verbose" = FALSE)

# ENABLE
options("ISAnalytics.verbose" = TRUE)

Some functions also produce report in a user-friendly HTML format, to set this feature:

# DISABLE HTML REPORTS
options("ISAnalytics.widgets" = FALSE)

# ENABLE HTML REPORTS
options("ISAnalytics.widgets" = TRUE)

2 Aggregating metadata

We refer to information contained in the association file as “metadata”: sometimes it’s useful to obtain collective information based on a certain group of variables we’re interested in. The function aggregate_metadata does just that: according to the grouping variables, meaning the names of the columns in the association file to perform a group_by operation with, creates a summary. You can fully customize the summary by providing a “function table” which tells the function which operation should be applied to which column and what name to give to the output column. A default is already supplied:

knitr::kable(default_meta_agg())

Column	Function	Args	Output_colname
FusionPrimerPCRDate	~suppressWarnings(min(.x, na.rm = TRUE))	NA	{.col}_min
LinearPCRDate	~suppressWarnings(min(.x, na.rm = TRUE))	NA	{.col}_min
VCN	~suppressWarnings(mean(.x, na.rm = TRUE))	NA	{.col}_avg
ng DNA corrected	~suppressWarnings(mean(.x, na.rm = TRUE))	NA	{.col}_avg
Kapa	~suppressWarnings(mean(.x, na.rm = TRUE))	NA	{.col}_avg
ng DNA corrected	~sum(.x, na.rm = TRUE)	NA	{.col}_sum
ulForPool	~sum(.x, na.rm = TRUE)	NA	{.col}_sum
BARCODE_MUX	~sum(.x, na.rm = TRUE)	NA	{.col}_sum
TRIMMING_FINAL_LTRLC	~sum(.x, na.rm = TRUE)	NA	{.col}_sum
LV_MAPPED	~sum(.x, na.rm = TRUE)	NA	{.col}_sum
BWA_MAPPED_OVERALL	~sum(.x, na.rm = TRUE)	NA	{.col}_sum
ISS_MAPPED_PP	~sum(.x, na.rm = TRUE)	NA	{.col}_sum

You can either provide purrr-style lambdas (as given in the example above), or simply specify the name of the function and additional parameters as a list in a separated column. If you choose to provide your own table you should maintain the column names for the function to work properly.

2.1 Typical workflow

Import the association file via import_assocition_file. If you need more information on import function please view the vignette “How to use import functions”.

withr::with_options(list(ISAnalytics.widgets = FALSE), {
    path_AF <- system.file("extdata", "ex_association_file.tsv",
        package = "ISAnalytics"
    )

    root_correct <- system.file("extdata", "fs.zip",
        package = "ISAnalytics"
    )
    root_correct <- unzip_file_system(root_correct, "fs")
    association_file <- import_association_file(path_AF, root_correct)
})
#> *** Association file import summary ***
#> i For detailed report please set option 'ISAnalytics.widgets' to TRUE
#> * Parsing problems detected: TRUE
#> * Date parsing problems: TRUE
#> * Column problems detected: TRUE
#> * NAs found in important columns: TRUE
#> * File system alignment: no problems detected
#> *** Association file import summary ***
#> i For detailed report please set option 'ISAnalytics.widgets' to TRUE
#> * Parsing problems detected: TRUE
#> * Date parsing problems: TRUE
#> * Column problems detected: TRUE
#> * NAs found in important columns: TRUE
#> * File system alignment: no problems detected

Perform aggregation:

aggregated_meta <- aggregate_metadata(
  association_file,
    grouping_keys = c(
        "SubjectID",
        "CellMarker",
        "Tissue", 
        "TimePoint"
    )
)

SubjectID	CellMarker	Tissue	FusionPrimerPCRDate_min	LinearPCRDate_min	VCN_avg	Kapa_avg	ulForPool_sum
VA2020-mix10	NA	NA	NA	NA	0.70	26.54667	25.70
VA2020-mix11	NA	NA	NA	NA	2.80	59.81000	12.29
VA2020-mix12	NA	NA	NA	NA	4.30	79.80333	7.98
VA2020-mix13	NA	NA	NA	NA	9.89	85.87000	7.46
VA2020-mix14	NA	NA	NA	NA	NaN	NaN	0.00

3 Aggregation of values by key

ISAnalytics contains useful functions to aggregate the values contained in your imported matrices based on a key, aka a single column or a combination of columns contained in the association file that are related to the samples.

3.1 Typical workflow

Import your association file (see previous section) and then import your matrices:

withr::with_options(list(ISAnalytics.widgets = FALSE), {
    matrices <- import_parallel_Vispa2Matrices_auto(
        association_file = association_file, root = NULL,
        quantification_type = c("fragmentEstimate", "seqCount"),
        matrix_type = "annotated", workers = 2, patterns = NULL,
        matching_opt = "ANY", multi_quant_matrix = FALSE
    )
})

The function aggregate_values_by_key can perform the aggregation both on the list of matrices and a single matrix.

# Takes the whole list and produces a list in output
aggregated_matrices <- aggregate_values_by_key(matrices, association_file)

# Takes a single matrix and produces a single matrix as output
aggregated_matrices_single <- aggregate_values_by_key(
    matrices$seqCount,
    association_file
)

3.1.1 Changing parameters to obtain different results

The function has several different parameters that have default values that can be changed according to user preference.

Changing the key value
You can change the value of the parameter key as you see fit. This parameter should contain one or multiple columns of the association file that you want to include in the grouping when performing the aggregation. The default value is set to c("SubjectID", "CellMarker", "Tissue", "TimePoint") (same default key as the aggregate_metadata function).

agg1 <- aggregate_values_by_key(
    x = matrices$seqCount,
    association_file = association_file,
    key = c("SubjectID", "ProjectID")
)

chr	integration_locus	strand	GeneName	GeneStrand	SubjectID	ProjectID	Value_sum
1	4519734	+	LINC01777	+	VA2020-mix10	CLOEXP	2
1	4519734	+	LINC01777	+	VA2020-mix10	PROJECT1100	4
1	4519734	+	LINC01777	+	VA2020-mix10	PROJECT1101	2
1	8426336	-	RERE	-	VA2020-mix10	CLOEXP	1
1	8426336	-	RERE	-	VA2020-mix10	PROJECT1100	2
1	8426336	-	RERE	-	VA2020-mix10	PROJECT1101	1

Changing the lambda value
The lambda parameter indicates the function(s) to be applied to the values for aggregation. lambda must be a named list of either functions or purrr-style lambdas: if you would like to specify additional parameters to the function the second option is recommended. The only important note on functions is that they should perform some kind of aggregation on numeric values: this means in practical terms they need to accept a vector of numeric/integer values as input and produce a SINGLE value as output. Valid options for this purpose might be: sum, mean, median, min, max and so on.

agg2 <- aggregate_values_by_key(
    x = matrices$seqCount,
    association_file = association_file,
    key = "SubjectID",
    lambda = list(mean = ~ mean(.x, na.rm = TRUE))
)

chr	integration_locus	strand	GeneName	GeneStrand	SubjectID	Value_mean
1	4519734	+	LINC01777	+	VA2020-mix10	2
1	8426336	-	RERE	-	VA2020-mix10	1
1	8884086	-	RERE	-	VA2020-mix11	1
1	11322005	-	MTOR	-	VA2020-mix10	1
1	11772847	+	DRAXIN	+	VA2020-mix11	13
1	22453532	+	WNT4	-	VA2020-mix10	2

Note that, when specifying purrr-style lambdas (formulas), the first parameter needs to be set to .x, other parameters can be set as usual.

You can also use in lambda functions that produce data frames or lists. In this case all variables from the produced data frame will be included in the final data frame. For example:

agg3 <- aggregate_values_by_key(
    x = matrices$seqCount,
    association_file = association_file,
    key = "SubjectID",
    lambda = list(describe = psych::describe)
)

#> # ... with 1,262 more rows

Changing the value_cols value
The value_cols parameter tells the function on which numeric columns of x the functions should be applied. NOte that every function contained in lambda will be applied to every column in value_cols: resulting columns will be named as “original name_function applied”.

## Obtaining multi-quantification matrix
comp <- comparison_matrix(matrices)

agg4 <- aggregate_values_by_key(
    x = comp,
    association_file = association_file,
    key = "SubjectID",
    lambda = list(sum = sum, mean = mean),
    value_cols = c("seqCount", "fragmentEstimate")
)

1	22453532	+	WNT4	-	VA2020-mix10	8	2	4.005724	1.001431

Changing the group value
The group parameter should contain all other variables to include in the grouping besides key. By default this contains c("chr", "integration_locus", "strand", "GeneName", "GeneStrand"). You can change this grouping as you see fit, if you don’t want to add any other variable to the key, just set it to NULL.

agg5 <- aggregate_values_by_key(
    x = matrices$seqCount,
    association_file = association_file,
    key = "SubjectID",
    lambda = list(sum = sum, mean = mean),
    group = c(mandatory_IS_vars())
)

chr	integration_locus	strand	SubjectID	Value_sum	Value_mean

1	11772847	+	VA2020-mix11	52	13
1	22453532	+	VA2020-mix10	8	2
