Dear Greg, dear all,
thank you for your reply!
To clarify, here is an example of what I want to do (but better, of
course!):
x<- c(1,2,3,4,5)
y<- 0:4
y2<- c(0,0,7,8,9)
barplot(y ,ylim=c(-1,10), ylab="", xaxt="n",yaxt="n", main="")
axis(4,at=c(1,2,3,4,5,6))
text(6,2.9, "2nd y-axis", srt = 270, xpd = TRUE)
par(new=TRUE)
plot(x, y2, lty=2,type="l", xlab="x-axis", ylab= "y-axis")
I dont think "barplot" is the right thing to use here since I cant specify
the x-values....what can I do to make this graph look better?
Regards,
Anne-Katrin
Using par(new=TRUE) can be tricky.
A better approach is to create one plot, then add the other information
to it. You can add bars to an existing graph using barplot with
add=TRUE, you can add lines to an existing plot using the lines function.
If you give more detail of what you want (examples of x,
y, and ynew) then we may be able to give more help.

Subject: [R] two graphs in one figure?
Dear all,
how can I plot a line graph and a bar graph in one single figure? I tried
to combine "barplot" and "plot". Even though they both have the same
x-values (1 to 55), it just doesnt look as if they match in their scale
(the barplot is much wider than the "plot"....even though I tried to put
limits on the x-axis).
Here is an example of what I did:
barplot(y, xaxt="n",yaxt="n",ylim=c(-1,45), xlim=c(1,55))
...
par(new=TRUE)
plot(x, ynew, lty=2, type="l", ylim=c(0,15), xlim=c(1,55))
Another question: how can I make sure that the "0"-values from the
barchart
are displayed as well?
Thank you so much!
Anne-Katrin
