head() function in R package dplyr

Question

This is a minor issue but in R when you type head(data.frame) you get the first few records from all the columns displayed. In the dplyr package the head function has been altered to only show the columns that can fit in your console window. This is often nice, but often I want to see the first few records for all the columns. Is there a way to tell head (in dplyr) to show all columns without converting the tbl.df/data.frame to a data.frame (and I prefer head to str()).

Thanks!

Answer 1

you can now use the glimpse() verb in dplyr 0.2 :

from https://github.com/hadley/dplyr/releases :

"glimpse() makes it possible to see all the columns in a tbl, displaying as much data for each variable as can be fit on a single line."

Answer 2

As Arun said, it's because of the print.tbl_df method. Just do:

print.data.frame(head(your_dplyr_dataframe))
