The with() construct gets a little more complicated if you want to do 
more than one thing inside:

for(i in levels(fHCGB$code)) with(subset(fHCGB,code==i), {
  plot(pooledPlateIntra, type="b", ylim=ylim, xlab=code, ylab="CV%")
  points(fHCGB$limitVarC,type="b", col="green")
})

or, since with() is really only needed for the plot()

for(i in levels(fHCGB$code)) {
  with(subset(fHCGB,code==i), 
 plot(pooledPlateIntra, type="b", ylim=ylim, xlab=code, ylab="CV%"))
  points(fHCGB$limitVarC,type="b", col="green")
}


(& you might have used lines() rather than points() if you think of it as an 
added line, but that's a matter of taste since the two functions only differ in 
the default for type=.)

Dear Taija,

You want lines but use points? Try 

for(i in levels(fHCGB$code)){
  with(subset(fHCGB,code==i), 
plot(pooledPlateIntra, type="b", ylim=ylim, xlab=code, ylab="CV%")
lines(fHCGB$limitVarC, col="green"))
}

Cheers,

Thierry

[R] Lines to plots with a for-loop

2007-06-05 Thread Saanisto, Taija
Hello all,

I'm plotting several graphs with a for-loop with a code:

par(mfrow=c(3,4))

for(i in levels(fHCGB$code)) with(subset(fHCGB,code==i),
plot(pooledPlateIntra, type="b", ylim=ylim, xlab=code, ylab="CV%"))


With which I have no problems.. However I need to add lines to all of
these 12 plots, but I cannot get it to work. I've tried for example

par(mfrow=c(3,4))

for(i in levels(fHCGB$code)) with(subset(fHCGB,code==i),
plot(pooledPlateIntra, type="b", ylim=ylim, xlab=code, ylab="CV%")
points(fHCGB$limitVarC,type="b", col="green")))

But run into errors. How can the lines be added?
