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
I think he meant RGtk2, and 'attempt to install'.
# 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.
You didn't show us the actual message, though, nor tell us if you were
doing a source package install (or if a binary one, where you got
binaries from). I suspect it came from RGtk2 and actually means that
you do not have all the RGtk2-related development packages installed.
I had something similar (given the vagueness of your description)
yesterday on Solaris, when the issue was that I missing gnome-devel (I
did have gtk-2.0-devel installed).
It is unlikely that you have the components but they are too old. The
stated minimum requirement is Gtk 2.8.0 (August 2005).
If you download and unpack the RGtk2 tarball and run R CMD INSTALL on
it there will be a file RGtk2/config.log: that is what told me what it
thought I had missing.
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?
Regards...
