| pillar {pillar} | R Documentation |
pillar() formats a vector using one row for a title (if given),
one row for the type, and length(x) rows for the data.
pillar(x, title = NULL, width = NULL, ...)
x |
A vector to format. |
title |
An optional title for the column. The title will be used "as is", no quoting will be applied. |
width |
Default width, optional. |

A pillar consists of a capital and a shaft.
The capital is constructed using the (currently internal)
pillar_capital() function, which uses the title argument
and calls type_sum() to format the type.
For the shaft, the pillar_shaft() generic is called with the object.
The returned value is stored and processed with format() when displaying the pillar.
The call to format() has a valid width argument.
Depending on the implementation,
the output representation can be computed eagerly right away (as done with new_pillar_shaft_simple()),
or only when format() is called.
The latter allows for adaptive shortening of the output depending on the available width,
see pillar:::pillar_shaft.numeric for an example.
x <- 123456789 * (10 ^ c(-1, -3, -5, NA, -8, -10))
pillar(x)
pillar(-x)
pillar(runif(10))
pillar(rcauchy(20))
# Special values are highlighted
pillar(c(runif(5), NA, NaN, Inf, -Inf))
# Very wide ranges will be displayed in scientific format
pillar(c(1e10, 1e-10), width = 20)
pillar(c(1e10, 1e-10))
x <- c(FALSE, NA, FALSE, FALSE, TRUE, FALSE, FALSE, TRUE, FALSE, TRUE)
pillar(x)
x <- c("This is string is rather long", NA, "?", "Short")
pillar(x)
pillar(x, width = 30)
pillar(x, width = 5)
