发帖数: 469 | 1 请问下面的R Code 怎么用Loop来实现？
这里的comb是list.
先谢谢了！
comb$I.1<-as.integer(as.character(comb$I.1))
comb$I.2<-as.integer(as.character(comb$I.2))
comb$I.3<-as.integer(as.character(comb$I.3))
comb$I.4<-as.integer(as.character(comb$I.4))
comb$I.5<-as.integer(as.character(comb$I.5)) |

comb <- lapply(comb,function(x){as.integer(as.character(x))})

发帖数: 469 | 7 Maybe I don't describe my problem so clearly, sorry for this.
I just need some columns of the list to do the conversion from factor to
integer. I can take those columns I like to convert to make a new list, then
try your code. It shows no errors, but the conversion didn't work by
checking the output.

发帖数: 100 | 8 I am a little confused, I thought you want the conversion for the whole
list, anyway, your problem was solved:)
