strwrap
Wrap Character Strings for Paragraph Formatting
Description
Breaks up character strings at spaces into strings of
specified width so they can be printed as paragraphs.
Usage
strwrap(x, width=0.9 * options()$width, indent=0, exdent=0,
prefix="", simplify=TRUE, initial=prefix)
Arguments
| x |
a character vector. The character strings in it should consist of
words separated by spaces or tabs.
|
| width |
a positive integer indicating the desired maximum length
of an output string.
|
| indent |
a non-negative integer indicating how many spaces to insert
at the start of each output paragraph.
|
| exdent |
a non-negative integer indicating how many spaces to insert
at the start of each non-initial line in an output paragraph.
|
| prefix |
a character string to prepend to each non-empty line.
|
| simplify |
a logical. The default TRUE produces a single character
vector of line text. Otherwise, it produces a list of the same length as
x. In this case, the elements of the resulting list are
character vectors of the line text obtained from the corresponding element of
x.
|
| initial |
a character string to be used like the prefix argument on the first non-empty line.
|
Details
Any white space contained in the input is removed. Double spaces after periods are
retained.
