wordwrap {pathview} | R Documentation

## Wrap or break strings into lines of specified width

### Description

strfit does hard wrapping, i.e. break within long words, wordwrap is a wrapper of strfit but also provides soft wrapping option, i.e. break only between words, and keep long words intact.

### Usage

    wordwrap(s, width = 20, break.word = FALSE)
    strfit(s, width = 20)

### Arguments

`s` | characcter, strings to be wrapped or broken down.
`width` | integer, target line width in terms of number of characters. d width=20.
`break.word` | logical, whether to break within words or only between words as to fit the line width. Default break.word=FALSE, i.e. keep words intact and only break between words. Therefore, some line may exceed the `width` limit.

### Details

These functions are called as to wrap long node labels into shorter lines on pathway graphs in `keggview.graph` function (when keggview.native=FALSE). They are equally useful for wrapping long labels in other types of graphs or output formats.

### Value

character of the same length of `s` except that each element has been wrapped softly or hardly.
