tibble-package: Simple Data Frames
Description
Provides a 'tbl_df' class that offers better checking and
printing capabilities than traditional data frames.
Methods
tbl_df implements four important base methods:
- print
- By default only prints the first 10 rows (at most 20), and the
columns that fit on screen; see
print.tbl_df [- Never simplifies (drops), so always returns data.frame
[[, $- Calls
.subset2 directly,
so is considerably faster. Returns NULL if column does not exist,
$ warns.
Package options
Display options for tbl_df, used by trunc_mat and
(indirectly) by print.tbl_df.
tibble.print_max- Row number threshold: Maximum number of rows
printed. Set to
Inf to always print all rows. Default: 20. tibble.print_min- Number of rows printed if row number
threshold is exceeded. Default: 10.
tibble.width- Output width. Default:
NULL (use
width option). tibble.max_extra_cols- Number of extra columns
printed in reduced form. Default: 100.
Details
The S3 class tbl_df wraps a local data frame. The main
advantage to using a tbl_df over a regular data frame is the printing:
tbl objects only print a few rows and all the columns that fit on one screen,
describing the rest of it as text.
