filter a data.frame
Hello, Mat, see below.
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$No==no.ind),]
in no.ind i have the 2 numbers: c("2","3")
but this doesn't work.
You should not expect a vector (of two elements), here no.ind, equal elementwise any of the elements of another (longer) vector, here out$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),]
