edge_mapping_info {KEGGlincs} | R Documentation

## Prepare edges for mapping

### Description

Modify the mapping information for desired look when graphed in Cytoscape

### Usage

    edge_mapping_info(expanded_edges, data_added = FALSE,
      significance_markup = FALSE, tidy_edge = TRUE)

### Arguments

`expanded_edges` | The data frame object generated via the function expand_KEGG_edges() OR has been modified by the function add_edge_data()
`data_added` | A logical indicator; must be set to TRUE if user data has been added (i.e. edges modified by function add_edge_data())
`significance_markup` | A logical indicator; if set to TRUE will color edges based on direction and significance of correlation (as determined by user-data-analysis)
`tidy_edge` | A logical indicator; must be set to FALSE for expanded edges

### Value

A data.frame object for edges that will be passed on to the function get_graph_object

### Examples

    p53_KGML <- get_KGML("hsa04115")
    p53_KEGG_mappings <- expand_KEGG_mappings(p53_KGML)

    #Default; no data added to edges:

    p53_edges <- expand_KEGG_edges(p53_KGML, p53_KEGG_mappings)
    p53_edge_mapping_info <- edge_mapping_info(p53_edges)

    #If data is added to edges as additional attribute[s]:

    p53_HA1E_data <- overlap_info(p53_KGML, p53_KEGG_mappings,
                                   "HA1E", data_type = "100_bing")

    p53_edges_HA1E_data_MAPPED <- add_edge_data(p53_edges, p53_KEGG_mappings,
                                                p53_HA1E_data,
                                                data_column_no = c(3, 10,12),
                                                only_mapped = TRUE)

    p53_edge_mapping_HA1E <- edge_mapping_info(p53_edges_HA1E_data_MAPPED,
                                                          data_added = TRUE)
