Hi Karthic,
You have things a little mixed around there-- use plotting commands after
you open an output device. Like so:
jpeg( "histogram.jpeg" )
hist( rnorm(100) )
And when you're done, don't forget to call dev.off(). As you mentioned that
you are a beginner, I would strongly suggest flipping through the
"Introduction to R" manual. A copy can be accessed online at:
http://cran.r-project.org/doc/manuals/R-intro.html
Section 12 provides a good overview of graphics in R.
Good luck!
-Charlie
