numeric inputs to sweep produce NaN...
I have two inputs to sweep which are numeric (with a few NA's) but the output is NaN. How Why?
sum(!is.numeric(unlist(protquant)))
[1] 0
sum(!is.numeric(normalize))
[1] 0
normprotquant <- sweep(protquant, 2, normalize, "-" ) sum(is.nan(unlist(normprotquant)))
[1] 31 version R 3.3.0 best regards Witold
