strtrim: Trim Character Strings to Specified Display Widths
Description
Trim character strings to specified display widths.
Usage
strtrim(x, width)
Arguments
x
a character vector, or an object which can be coerced to a
character vector by as.character.
width
Positive integer values: recycled to the length of x.
Value
A character vector of the same length and with the same attributes
as x (after possible coercion).Elements of the result will have the encoding declared as that of
the current locale (see Encoding) if the corresponding
input had a declared encoding and the current locale is either Latin-1
or UTF-8.
Details
‘Width’ is interpreted as the display width in a monospaced
font. What happens with non-printable characters (such as backspace, tab)
is implementation-dependent and may depend on the locale (e.g., they
may be included in the count or they may be omitted).
Using this function rather than substr is important when
there might be double-width (e.g., Chinese/Japanese/Korean) characters
in the character vector.
