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? _____________________________________ search <- c(1,3,5) x <- data.frame(A = c(1:5), B = c(1,1,2,2,2)) x[x$B == 2 & x$A == search,] ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
