I would wote this question one of the most often asked questions here on
that list ;-). Try searching the help archiwe (www.rseek.org) and you
will find solutions. I would guess that you need to use something like:
axis(4)
as the sides of the plot are always numbered from bottom,left,top,right

here ,I want to plot two lines in one figure.But I have two problems
1) how to move one of the y-axis to be the right ? I tried to the
command"axis(2)",But I failed.
2) how to add the axis information correctly.Since I have use the cmommand
"axis(1,at=1:6,labels=gradeinfo$gradenam)"
but it seems that the correct information that I want is superposition
with the old axis information.What can i do ?
the script and figure is shown as below .thanks .:)

par(las=1)
yylab<-c("forecast error")
xxlab<-c("typhoon class")
llty<-c(1,3)
llwd<-c(4,4)
#par(bg='yellow')
plot(avegrp,type='l',lty=1,col='black',lwd=4,xlab=xxlab,ylab=yylab)
par(new=T)
plot(sdgrp,type='l',lty=3,col='red1',xlab=xxlab,ylab=yylab,lwd=4)
#axis(2, col = "gold", lty = 2, lwd = 0.5)
legend("topright", legend, lty=llty, lwd=llwd,col =lgcol)
axis(1,at=1:6,labels=gradeinfo$gradenam)
