R: Size of a character string in current font

stringSize {ifultools} | R Documentation

## Size of a character string in current font

### Description

Calculates the approximate relative x and y spans of the input character string x in the current par("usr") coordinates. The `srt`, `adj`, and `cex` inputs are exactly those specified by the `par` function.

### Usage

    stringSize(x, srt=0, adj=0.5, cex=1)

### Arguments

`x` | a character string.
`adj` | a numeric value on the interval [0,1] used to justify the text relative to its placement in a plot. Default: 0.5 (center aligned).
`cex` | the expansion value for the character string. Default: 1.
`srt` | a numeric value defining the amount of string rotation in degrees. Default: 0.

### Value

a list of x- and y-vectors that can be used to estimate the width and height, respectively, of the input character string in the current par("usr") coordinates. Each vector contains a relative starting and ending value and the absolute difference between the two values repesents the span in the corresponding direction.

### Examples

    stringSize("What's for dinner?", adj=0, srt=45, cex=1.5)
