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.
