Hi!
I'm puzzled by the return value of ifelse
consider
x<-integer(0)
ifelse(is(x, "character"), paste(x), x)
[1] NA
whereas
if (is(x, "character")) return(paste(x)) else x
[1] integer(0)
or
x<-integer(1)
ifelse(is(x, "character"), paste(x), x)
[1] 0
work as I had anticipated. Is this correct behaviour?
Regards,
Matthias
