[R] multiple logical comparisons

[Martin Batholdy]

Hi,

I would like to compare a column of data with a vector.

I have this data.frame for example;

x <- data.frame(A = c(1:5), B = c(1,1,2,2,2))

Now I have a search vector:

search <- c(1,3,5)


when I now try to get all the data-rows which have a 1, a 3, or a 5 in column A and a 2 in column B, 
I tried this:

x[x$B == 2 & x$A == search,]


I hoped to get 
3 2
5 2
as output.


But I get an empty set.


Can someone help me on that?

x[x$B == 2 & x$A == search,]
