[R] kernel density plot

I am using the following commands for plotting kernel density for three kinds of crops

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

the problem is that in the graph that is drawn

  1. the xlab gets hidden with the [N= and the bandwidth=] values
  2. when i do par(new=T) this N and bandwidth value appears multiple times..overlapping each time and making the graph look untidy..

Is there any way of making these N and Bandwidth values not appear in the graph?

Thanks
