Bash script that uses an R command

I have wriiten (with the help of the internet) a bash scirpt for my
debian ppc 5.0 laptop to display battery remaining in a panel on the
xfce desktop environment.

echo `hal-device | grep battery.remaining_time | awk '{print $3/3600}' `-battery

and this nicely spits out ?4.95 hours in the panel. ?This is fine
except it is a snow day and I have some extra time on my hands. ?I was
wondering if I could write a little program that would take 4.95 and
convert it into 4: (.95*6) in other words 4:57 in R and then use that
in a shell script to tweak the battery remaining script. ?I am sure
there is a better way, but I am a noob to linux and have a couple of
years with R.
thanks

This is one for little r (http://dirk.eddelbuettel.com/code/littler.html)

$ echo "4.95" | r -e "x <- as.numeric(readLines()); cat( floor(x),':',
round( ( x - floor( x ) ) * 60 ),'\n',sep='') "
4:57

echo 'hal-device | grep battery.remaining_time | awk '{print$3/3600}'
| awk '{print int($1)}":"int(60*($1-int($1)))'`

here is the final shell script is anyone is interested - this is
written and working in debian linux
