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.
See ?%in%
x[x$B == 2 & x$A %in% search, ]
