Use a list instead of assign then do.call("rbind", thelist).
import.files <- c("a.txt", "b.txt", "c.txt", "d.txt", "e.txt")
imp <- vector("list", length(import.files))
for (i in 1:length(import.files)) {
imp[[i]] <- read.delim(import.files[i], sep = "", header = TRUE)
}
combined <- do.call("rbind", imp)
