Another way: If x is a two column matrix, as suggested by Henrique D.,
ID Value 1 7 0.000656733 2 6 0.201764789 3 1 0.671113391 4 10 -0.739727826 5 9 -1.111310154 6 5 -0.859455833 7 2 -1.408229877 8 8 0.993126295 9 3 -0.171906808 10 4 -0.140107677 And you are looking up the value corresponding to "ID" ID <- 4 x[(1:dim(x)[1])[x[,1]==ID],2] will also do it, and you can vary the value of the 2 in order to query the column of interest, much as you can do with vlookup in the E program.
