Join data frame columns
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 Em 23-10-2012 14:13, brunosm escreveu:
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! -- View this message in context: http://r.789695.n4.nabble.com/Join-data-frame-columns-tp4647113p4647132.html Sent from the R help mailing list archive at Nabble.com.
