search for: name_y

Hello All, I have multiple "list of lists" in the form of Mylist1[[N]][[K]]$Name_i, with N=1..6, K=1..3, and i=1..7. Each Name_i is a matrix. I have 30 of these objects Mylist1, Mylist2, ... I would like to merge these lists by each Name_i using rbind, but I couldn't figure out how to do it. What I want at the end is a single "list of lists", again in the form of

...lnames(arun_1986) [1] "Latitude" "Longitude" "Sim_1986" > colnames(fekete_1986) [1] "Latitude" "Longitude" "X1986" I'm trying to merge based on both the Latitude and Longitude column and have used by=c("name_x", "name_y") before without too many problems. Any suggestions would be gratefully received. Many thanks, Steve
