Hi Roslina,
You only specify space for two plots in:
par(mfrow=c(1,2))
However, you only try to plot two plots, so I will assume that you
only want two. You haven't defined "x" in the above code, which will
cause an error. The code below gives me two plots as I would expect (I
made up the data that you didn't supply).
par(mfrow=c(1,2))
stn_all<-matrix(400*rnorm(20)+4,ncol=2)
par(mar=c(4,4,2,1.2),oma=c(0,0,0,0),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()

Dear r-users,
I would like to plot 4 graphs arranged as 2 by 2 and follows are my
codes.
However, it only shows one graph.
par(mfrow=c(1,2))
par(mar=c(4,4,2,1.2),oma=c(0,0,0,0),xaxs="i", yaxs="i") ## To control
white space around and between the plots

Thank you for your help.
