R packages - Apr 2010 - formatR: farewell to ugly R code

This is an announcement of the release of an R package 'formatR',
which can help us format our R code to make it more human-readable. If
you have ugly (I mean unformatted) R code like this:

?# rotation of the word "Animation"
# in a loop; change the angle and color
# step by step
for (i in 1:360) {
?    # redraw the plot again and again
plot(1,ann=FALSE,type="n",axes=FALSE)
# rotate; use rainbow() colors
text(1,1,"Animation",srt=i,col=rainbow(360)[i],cex=7*i/360)
# pause for a while
Sys.sleep(0.01)}

There are no spaces, no appropriate indent... The package 'formatR'
provides a GUI (by gWidgets) to make messy R code clean and tidy, e.g.

# rotation of the word 'Animation'
# in a loop; change the angle and color
# step by step
for (i in 1:360) {
? ?# redraw the plot again and again
? ?plot(1, ann = FALSE, type = "n", axes = FALSE)
? ?# rotate; use rainbow() colors
? ?text(1, 1, "Animation", srt = i, col = rainbow(360)[i],
? ? ? ?cex = 7 * i/360)
? ?# pause for a while
? ?Sys.sleep(0.01)
}

The usage is simple:

# formatR depends on RGtk+; will be installed automatically
# better use the latest version of R (>=2.10.1)
install.packages('formatR')
library(formatR)
# or formatR()

Interested in adding this package but when I tried to load it and its
dependencies the system spit back that I didn't have the right version of
Gtk. I'm running Ubuntu Linux 8.04 (Hardy Heron) with all the called for
updates. I've looked in synaptic but I'm not an 'under the hood'
type of
user so I have no clue what to look for in there to find out what I have or
even if it is possible to update. Oh yes, I'm running v2.10.1 of R.

Is there any likely solution to this situation, or am I SOL because my
Linux version is now simply too old?
