Hello,
If I have a dataframe:
example(data.frame)
zz<-c("aa_bb","bb_cc","cc_dd","dd_ee","ee_ff","ff_gg","gg_hh","ii_jj","jj_kk","kk_ll")
ddd <- cbind(dd, group = zz)
and I want to divide the column named group by the "_", how would I do this?
so instead of the first row being
x y fac char group
1 1 C a aa_bb
it should be:
x y fac char group_a group_b
1 1 C a aa bb
I know for a vector I can:
x1 <- c("a_b","b_c","c_d")
do.call("rbind",strsplit(x1, "_"))
but I am not sure how this relates to my data.frame
Thanks,
Daisy
