Subsetting R with “IN” like operator

Question

I'm trying to subset using a vector of characters. I'd like to pull back all rows whose corresponding X column are in this vector. My experimenting is bringing back zilch and so is my search.

list<-c("1","2","3")
sub<-subset(data,x==list,1:4)

That and syntax pretty close to it won't work.

Thanks!

As mentioned by @bunk you could use the %in% operator:

DF <- data.frame(id=c(1,2,3),val=c(4,5,6))
val.list <- c(5,6)
subDF <- subset(DF, val %in% val.list)
subDF
  id val
2  2   5
3  3   6
