convertRowID {scTGIF} | R Documentation

## A function to change the row names of a matrix.

### Description

To avoid to specify the duplicated row names against matrix, multiple aggregation rules are implemented.

### Usage

    convertRowID(input, rowID, LtoR,
        aggr.rule=c("sum", "mean", "large.mean", "large.var", "large.cv2"))

### Arguments

`input` | A matrix filled with number (n * m).
`rowID` | A vector to specify the row names of input (length: n).
`LtoR` | A corresponding table to covert the row names of input as different type of IDs. (Left: current row names -> Right: new row names)
`aggr.rule` | The aggregation rule to change the row names of input and collapse/select the values, if the row names changed by LtoR are duplicated. sum: Collapses multiple row vectors by summation. mean: Collapses multiple row vectors by mean. large.mean: Select a vector having the largest mean in the duplicated vectors. large.var: Select a vector having the largest variance in the duplicated vectors. large.cv2: Select a vector having the largest CV2 in the duplicated vectors.

### Value

`output` | A matrix, in which the row names are changed, according to the aggregation rule user specified.
`ctable` | The corresponding table explaining the relationship between previous row names and changed row names of input.

### Examples

        input <- matrix(1:20, nrow=4, ncol=5)
        rowID <- c("A", "B", "C", "D")
        LtoR <- rbind(
          c("A", "3"),
          c("B", "2"),
          c("C", "4"),
          c("D", "7"))
        (input2 <- convertRowID(input, rowID, LtoR, "sum"))
        (input3 <- convertRowID(input, rowID, LtoR, "mean"))
        (input4 <- convertRowID(input, rowID, LtoR, "large.mean"))
        (input5 <- convertRowID(input, rowID, LtoR, "large.var"))
        (input6 <- convertRowID(input, rowID, LtoR, "large.cv2"))
