In jmw86069/splicejam: Analysis and Visualization of Gene Splice Variants and Transcriptome Data

Shrink numeric matrix by groups of rows

Description

Shrink numeric matrix by groups of rows

Usage

shrinkMatrix(
  x,
  groupBy,
  shrinkFunc = function(x) {
     .Internal(mean(x))
 },
  returnClass = c("data.frame", "matrix"),
  verbose = FALSE,
  ...
)

Arguments

x	numeric matrix
groupBy	vector of group labels, whose length equals nrow(x). These values will become rownames in the output data.
shrinkFunc	function that takes vector input and returns vector output. The vector class can be checked, in order to call a function on numeric or character data separately, as needed.
returnClass	character string indicating the return data type, "data.frame" returns a data.frame whose first column contains entries from groups; "matrix" returns a numeric matrix whose rownames are entries from groups.
verbose	logical indicating whether to print verbose output.

Details

This function is mainly a wrapper around the very efficient functions in the data.table package, with the ability to provide a custom function to shrink row values.
