Hello,
Sorry for my earlier post, I misunderstood what you want.
dat <- data.frame(letters, 1:26)
as.vector(sapply(d, as.character))
Hope this helps,
Rui Barradas

Hi Ivan, thanks for your help!
For example:
df
num letters
1 1 A
2 2 B
3 3 C
4 4 D
5 5 E
What i want is to join "num" and "letters" in a single column. Something
like this
new_df
1 1
2 2
3 3
4 4
5 5
6 A
7 B
8 C
9 D
10 E
I tried to do it with a list but it converts factors to numbers...
new_df<-list(c(df[,1],df[,2]))
new_df
[[1]]
[1] 1 2 3 4 5 1 2 3 4 5
Thanks!
