Well, if I understand you correctly, you want to find something in your table (data.frame) try: your.table==your.vector to get TRUE/FALSE table with same dimensions as your table and which(your.table==your.vector, arr.ind=T) to obtain row/col indices of TRUE values In case you want something else please try to be more specific.
