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 .:)

outflnm<-paste(Outdic,"meansd.jpg",sep="/") jpeg(file=outflnm, bg="transparent")
legend<-c("average error","stand quare error") lgcol<-c("black","red1")
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) dev.off()
