Hi, All
I am using is.integer function to examine whether an object is an integer or
not, but I get such results,
> x<-3
> is.integer(x)
[1] FALSE
> x<-3:4
> x
[1] 3 4
> is.integer(x)
[1] TRUE
Seems that the is.integer cannot handle scalers,
> is.integer(5)
[1] FALSE
> is.integer(5:6)
[1] TRUE
Is this a bug in R or I made some mistakes? I am using R 2.2.1 under Windows XP
Thanks a lot!
Leon
