R: combine list of lists into a single dataframe

I have a list (res) containing p x b number of dataframes. Each dataframe has 12 columns but varying number of rows (e.g, res[[1]][[1]] has 12 cols and 36 rows, but res[[1]][[1]] has 12 cols and 38 rows). I would like to combine them into a single dataframe that has 12 columns and 179 rows let's say. Thedo.call("rbind", listOfDataFrames) method doesn't work as I loose column and row information. Let me know, if further specification is needed. Many thanks!

In fact it is a list containing 5 elements. And the first element is a list of dataframes, whereas the other elements 2, 3, 4 and 5 are NULL. so you need to do access the first element of your list:

do.call(rbind, listOfDataFrames[[1]])

Or:

rbindlist(listOfDataFrames[[1]])
