Color text

Description

Add color to individual words in text functions. ctext, cmtext, and ctitle are analogous to text, mtext, and title, respectively. Note that title accepts some graphical parameters specific to the label type, e.g., col.main, but this is not implemented in ctitle–colors will be recycled if more than one label type is given. Similarly, further graphical parameters such as cex or line will be passed to all label types; see examples.

Usage

ctext(text, cols, space = TRUE, ...)

cmtext(text, cols, space = TRUE, ...)

ctitle(
  main = NULL,
  sub = NULL,
  xlab = NULL,
  ylab = NULL,
  cols,
  space = TRUE,
  ...
)

Arguments

text	vector of text
cols	vector of colors; should be the same lenght as text or will me recycled with a warning
space	logical; if TRUE, adds space between text
...	additional parameters passed to text or mtext
main, sub, xlab, ylab	vector(s) of text for specific labels

Examples

plot(1, ann = FALSE)
ctext(x = 1, y = 1, text = c('hello','little','point'), cols = 1:3, pos = 1)
cmtext(c('a','side','label'), 1:2, space = FALSE, side = 4, cex = 3)
cmtext(c('a','a','a'), 4:6, space = FALSE, side = 4, cex = 3, line = -2)

## note that line, cex, font, etc will be recycled
ctitle(main = c('the','main','label'), xlab = c('x','label'),
       ylab = c('y','label'), sub = c('sub', 'label'), col = 3:5)
ctitle(xlab = c('another','label'), ylab = c('another','label'),
       font = 3, col = 1:2, line = 2, cex = 1.5)
