| quo_label {rlang} | R Documentation |
quo_text() and quo_label() are equivalent to expr_text(),
expr_label(), etc, but they first squash all quosures with
quo_squash() so they print more nicely.
quo_name() squashes a quosure and transforms it into a simple
string. It is suitable to give an unnamed quosure a default name,
for instance a column name in a data frame.
quo_label(quo) quo_text(quo, width = 60L, nlines = Inf) quo_name(quo)
quo |
A quosure or expression. |
width |
Width of each line. |
nlines |
Maximum number of lines to extract. |
# Quosures can contain nested quosures: quo <- quo(foo(!! quo(bar))) quo # quo_squash() unwraps all quosures and returns a raw expression: quo_squash(quo) # This is used by quo_text() and quo_label(): quo_text(quo) # Compare to the unwrapped expression: expr_text(quo) # quo_name() is helpful when you need really short labels: quo_name(quo(sym)) quo_name(quo(!! sym))
