Format vectors of items and their descriptions as 2-column tables or LaTeX-style description lists.
formatDL(x, y, style = c("table", "list"),
width = 0.9 * getOption("width"), indent = NULL)a vector giving the items to be described, or a list of length 2 or a matrix with 2 columns giving both items and descriptions.
a vector of the same length as x with the
corresponding descriptions. Only used if x does not already
give the descriptions.
a character string specifying the rendering style of the
description information. Can be abbreviated.
If "table", a two-column table with
items and descriptions as columns is produced (similar to Texinfo's
@table environment). If "list", a LaTeX-style tagged
description list is obtained.
a positive integer giving the target column for wrapping lines in the output.
a positive integer specifying the indentation of the
second column in table style, and the indentation of continuation
lines in list style. Must not be greater than width/2, and
defaults to width/3 for table style and width/9 for
list style.
a character vector with the formatted entries.
After extracting the vectors of items and corresponding descriptions from the arguments, both are coerced to character vectors.
In table style, items with more than indent - 3 characters are
displayed on a line of their own.

writeLines(formatDL(unlist(.Machine)))
## Inspect Sys.getenv() results in "list" style (by default, these are
## printed in "table" style):
writeLines(formatDL(Sys.getenv(), style = "list"))
