Combine a list of data frames into one data frame by row

I have code that at one place ends up with a list of data frames which I really want to convert to a single big data frame. I got some pointers from an earlier question which was trying to do something similar but more complex. Here's an example of what I am starting with (this is grossly simplified for illustration): ``` listOfDataFrames <- vector(mode = "list", length = 100) for (i in 1:100) { listOfDataFrames[[i]] <- data.frame(a=sample(letters, 500, rep=T), b=rnorm(500), c=rnorm(500)) } ``` I am currently using this: ``` df <- do.call("rbind", listOfDataFrames) ```
