It would be easier to test and example if we knew what s22, s33, and s44 were, but you can try:

density(s22$Net_income_Total.1, bw="nrd0",adjust=1,
kernel=c("gaussian"))->t
plot(t, xlim=c(-30000,40000), main="Net Income Distribution", axes=F,
ylim=c(0,0.00035). xlab="Value in Rupees")
density(s33$Net_income_Total.1, bw="nrd0",adjust=1,
kernel=c("gaussian"))->u
lines(u,  col="red")
density(s44$Net_income_Total.1, bw="nrd0",adjust=1,
kernel=c("gaussian"))->v
lines(v, col="blue")

i am sorry greg, can you explain that with an example?

It is better to replace your later calls to plot with calls to lines instead, then you don't need to use par(new=T) which as you see tends to cause problems.
