Hi!

Here are a few tips to start finding what you need (in R):
apropos("pie")
RSiteSearch("pie")

Try also:
?pie
?barplot

I guess there are hundreds of commands to do every type of graphics, but
you can start there.
The manual "Using R for Data Analysis and Graphics" from JH Maindonald
is also quite good, among many others!

Hi chinna,
You can get all of these and more. What type of plot you want depends
upon what you want to illustrate:

# scatterplot - sprays all the values out with a
# different color for each store
plot(xyz$year_y,xyz$revenue,type="p",
col=as.numeric(xyz$store))
# barplot - shows you the relative positions of
# the stores in different years
# this example was done with the toy data I posted last time
barplot(as.matrix(
reshape(xyz,idvar="Store",timevar="Year",dir="wide")[,2:4])
,beside=TRUE)
legend(8,600000,levels(xyz$Store),fill=c("gray80","gray50","gray20"))
# pie chart - shows the mean revenue for each store
# over all the years sampled - again the previous toy data
pie(by(xyz$Revenue,xyz$Store,mean))

You have to decide on what you want to illustrate unless you are just
producing PlotArt, a new genre in which the artist produces random plots
of financial data to emphasize the meaninglessness of the materialistic
culture in which we pretend that we are happy, but

No, I can't keep a straight face anymore.

Your installation of R must be broken. I can easily get help pages for

?plot
?pie
?barplot
