isolNAneighb {wrProteo}

Isolate NA-neighbours

Description

This functions extracts all replicate-values where at least one of the replicates is NA and sorts by number of NAs per group. A list with all NA-neighbours organized by the number of NAs gets returned.

Usage

isolNAneighb(mat, gr, silent = FALSE, debug = FALSE, callFrom = NULL)

Arguments

mat

(matrix or data.frame) main data (may contain NA)

gr

(character or factor) grouping of columns of 'mat', replicate association

silent

(logical) suppress messages

debug

(logical) display additional messages for debugging

callFrom

(character) allow easier tracking of messages produced

Value

This function returns a list with NA-neighbours sorted by number of NAs in replicate group
