conv01toColNa
transforms matrix of integers (eg 0 and 1) to repeated & concatenated text from argument colNa
,
the character string for 0 occurances of argument zeroTex
may be customized.
Used eg when specifying (and concatenating) various counted elements (eg properties) along a vector like variable peptide modifications in proteomics.
conv01toColNa(mat, colNa = NULL, zeroTex = "", pasteCol = FALSE)
mat |
input matrix (with integer values) |
colNa |
alternative (column-)names to the ones from 'mat' (default colnames of 'mat') |
zeroTex |
text to display if 0 (default "") |
pasteCol |
(logical) allows to collapse all columns to single chain of characters in output |
character vector
(ma1 <- matrix(sample(0:3,40,repl=TRUE), ncol=4, dimnames=list(NULL, letters[11:14])))
conv01toColNa(ma1)
conv01toColNa(ma1, colNa=LETTERS[1:4], ze=".")
conv01toColNa(ma1, colNa=LETTERS[1:4], pasteCol=TRUE)
