strsplit by row and distribute results by column in data.frame

Question

So I have the data.frame

dat = data.frame(x = c(\'Sir Lancelot the Brave\', \'King Arthur\',  
                       \'The Black Knight\', \'The Rabbit\'), stri         


        

Answer 1

Here is a nice and simple approach with tidyr.

library(tidyr)

ncol <- max(sapply(dat, length))

dat %>%
  separate(x, paste0("V", seq(1,ncol)))

Note: You will get a warning, however, it is basically telling you that separate is padding the data with NA's. So you can ignore the warning.
