In PTXQC: Quality Report Generation for MaxQuant and mzTab Results

Same as byX, but with more flexible group size, to avoid that the last group has only a few entries (<50% of desired size).

Description

The 'subset_size' param is internally optimized using correctSetSize and then byX is called.

Usage

byXflex(data, indices, subset_size = 5, FUN, sort_indices = TRUE, ...)

Arguments

data	Data.frame whose subset to use on FUN
indices	Vector of group assignments, same length as nrow(data)
subset_size	Ideal number of groups to use in one subset – this can be changed internally, from 75%-150%
FUN	function Applied to subsets of data
sort_indices	Groups are formed by their sorted character(!) names
...	More arguments to FUN

Value

list of function result (one entry for each subset)

Examples

 stopifnot(
   byXflex(data.frame(d=1:10), 1:10, 2, sum, sort_indices = FALSE) ==
   c(3, 7, 11, 15, 19)
 )
