[R] Multiple plot in a page

[roslinazairimah zakaria]

Hi Duncan and Jim,

Yes, definitely you are right.  I should comment the third par().

par(mfrow=c(1,2))
stn_all<-matrix(400*rnorm(20)+4,ncol=2)

par(mar=c(4,4,2,1.2),oma = c(1, 1, 1, 1),xaxs="i", yaxs="i")
hist(stn_all[,1],prob=TRUE, main ="Balok ",col="yellowgreen", cex.axis=1.2,
xlab="Rain (mm)", ylab="Relative frequency", ylim= c(0,.004),
xlim=c(0,1200))
x<-c(400,600,800,1000)
dgam1<-(rnorm(4)+4)/2000
lines(x, dgam1,col="red",lwd=3)
legend("topright", legend = c("observed","fitted"),
       col = c("yellowgreen", "red"), pch=c(15,NA), lty = c(0, 1),
       lwd=c(0,3),bty="n", pt.cex=2)
text(100,.012 , expression(paste(beta==64.64)))
box()

#par(mar=c(4,4,2,1.2),oma=c(0,0,0,0),xaxs="i", yaxs="i")
hist(stn_all[,2],prob=TRUE, main ="Gambang ",col="yellowgreen",
cex.axis=1.2,
xlab="Rain (mm)", ylab="Relative frequency", ylim= c(0,.004),
xlim=c(0,1200))
dgam2<-(rnorm(4)+4)/2000
lines(x, dgam2,col="red",lwd=3)
legend("topright", legend = c("observed","fitted"),
       col = c("yellowgreen", "red"), pch=c(15,NA), lty = c(0, 1),
       lwd=c(0,3),bty="n", pt.cex=2)
text(100,.012 , expression(paste(beta==64.64)))
box()

Thank you.
