add_column: Add columns to a data frame

In krlmlr/tibble: Simple Data Frames

Description

This is a convenient way to add one or more columns to an existing data frame.

Usage

add_column(.data, ..., .before = NULL, .after = NULL)

Arguments

.data	Data frame to append to.
...	Name-value pairs, passed on to tibble(). All values must have one element for each row in the data frame, or be of length 1. These arguments are passed on to tibble(), and therefore also support unquote via !! and unquote-splice via !!!. However, unlike in dplyr verbs, columns in .data are not available for the expressions. Use dplyr::mutate() if you need to add a column based on existing data.
.before, .after	One-based column index or column name where to add the new columns, default: after last column.

add_column(df, x = 4:6)

## End(Not run)
# You can't create new observations
## Not run: 
add_column(df, z = 1:5)
