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

You should not expect a vector (of two elements), here no.ind, equal elementwise any of the elements of another (longer) vector, here out$No. You probably actually want to check for each element of out$No if it is contained in the set of elements in no.ind. 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:

thanks together, out1 <- out[(out$No %in% no.ind),] works perfectly :-) -- View this message in context: http://r.789695.n4.nabble.com/filter-a-data-frame-tp4682118p4682131.html Sent from the R help mailing list archive at Nabble.com.
