hello together, i want to filter a data.frame. My problem is, that i want to
filter 2 numbers.
My data.frame look like this one.
No. text
1 abc
2 def
3 ee
4 ff
5 gg
I want now to filter No. 2 and 3, so my solution should be look like this
one.
No. text
2 def
3 ee
i tried it like this one:
out1<-out[(out$No==no.ind),]
in no.ind i have the 2 numbers: c("2","3")
but this doesn't work.
Maybe anyone can help me.
Thank you.
Mat

So, use, e.g.,> out1 <- out[(out$No %in% no.ind),]See ?is.element. Hth -- Gerrit

Hello, Try instead no.ind <- c(2, 3) out1 <- out[out$No %in% no.ind, ] Hope this helps, Rui Barradas Em 13-12-2013 12:59, Mat escreveu:> hello together, i want to filter a data.frame.
