search for: m304

...303 ... m500 So I tried: mlist <- paste("m",302:500,sep="") dat <- do.call("rbind", get(list(mlist))) and I get "Error in get(x, envir, mode, inherits) : invalid first argument" I know "rbind" is valid because dat <- rbind(m302, m303, m304, m305) works, I am just too lazy to type it out to m500. I also tried it without the get() portion, but then dat ends up being a column with just the names of the objects, not the objects themselves. Thanks in advance for showing me the errors in my attempts. Roger
