Hello,
in one of my functions I have statements like this one:
out[mod1.no.mod2, c("Freq.Diff", "Freq.t")] <- ttt.1[mod1.no.mod2,
c("Diff.",
"t.value")]
mod1.no.mod2 is a character variable and is computed. Occasionnally
mod1.no.mod2 is empty, i.e. it is equal to «character(0)». In these
circumstances S+ complains and the function aborts returning the error:
Problem in out[mod1.no.mod2, c("Freq.Diff", "Freq.t")] <..: 0 rows in
value to replace 147 rows
The error message here is not quite correct since the 0 rows in value are
trying to replace 0 rows in "out"!
Is there ways around this without putting an if statement to check if
mod1.no.mod2 is empty or not, changing the mode of mod1.no.mod2 maybe? I'd
rather avoid the if statement since I have several similar assignements in
my function.
Thanks in advance,
Gérald Jean
