问题
tibble (previously tbl_df) is a version of a data frame created by the dplyr data frame manipulation package in R. It prevents long table outputs when accidentally calling the data frame.
Once a data frame has been wrapped by tibble/tbl_df, is there a command to view the whole data frame though (all the rows and columns of the data frame)?
If I use df[1:100,], I will see all 100 rows, but if I use df[1:101,], it will only display the first 10 rows. I would like to easily display all the rows to quickly scroll through them.
Is there either a dplyr command to counteract this or a way to unwrap the data frame?
回答1:
You could also use
print(tbl_df(df), n=40)
or with the help of the pipe operator
df %>% tbl_df %>% print(n=40)
To print all rows specify tbl_df %>% print(n = Inf)

You can use as.data.frame or print.data.frame.
If you want this to be the default, you can change the value of the dplyr.print_max option.
options(dplyr.print_max = 1e9)

The tibble vignette has an updated way to change its default printing behavior:
You can control the default appearance with options:
options(tibble.print_max = n, tibble.print_min = m): if there are more than n rows, print only the first m rows. Useoptions(tibble.print_max = Inf)to always show all rows.
options(tibble.width = Inf)will always print all columns, regardless of the width of the screen.
examples
This will always print all rows:
options(tibble.print_max = Inf)
This will not actually limit the printing to 50 lines:
options(tibble.print_max = 50)
But this will restrict printing to 50 lines:
options(tibble.print_max = 50, tibble.print_min = 50)

As detailed out in the bookdown documentation, you could also use a paged table
mtcars %>% tbl_df %>% rmarkdown::paged_table()
This will paginate the data and allows to browse all rows and columns (unless configured to cap the rows). Example:
