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. |
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](../../base/help/substr.html) is important when there might be double-width (e.g., Chinese/Japanese/Korean) characters in the character vector.
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](../../base/help/Encoding.html)) if the corresponding input had a declared encoding and the current locale is either Latin-1 or UTF-8.
Examples
strtrim(c("abcdef", "abcdef", "abcdef"), c(1,5,10))
