Hi ,

I want to know is this behavior expected and why is that ? Need some help

gender <- c("F", "M", "M", "F", "F", "M", "F", "F")

age    <- c(23, 25, 27, 29, 31, 33, 35, 37)
df<- data.frame(gender,age)
typeof(df[[1]])

[1] "integer"   >>>>>>>>>>>>>  Why is this integer . *Should not it be
character ?*

typeof(df[[2]])

[1] "double"

typeof(gender)

[1] "character"

typeof(age)

[1] "double"

In my code i am trying to do some thing based on typeof and the type for
character column is strange.

Thanks,
Sandip
