Combing a list of unequal data.frames

Question

I\'m trying to combine a list of unequal data.frames; the obvious do.call(rbind, df.lst) fails but the real problem is padding it out with NAs.

Answer 1

We can use

library(dplyr)
bind_rows(df.lst)

Or

library(data.table)
rbindlist(df.lst, fill=TRUE)
