Hi!
I need to plot two lines on the same graph. I do
plot(x,y)
then
plot(x,z,add=TRUE)
but I get the following warning messages
Warning messages:
1: parameter "add" couldn't be set in high-level plot() function
2: parameter "add" couldn't be set in high-level plot() function
3: parameter "add" couldn't be set in high-level plot() function
4: parameter "add" couldn't be set in high-level plot() function
5: parameter "add" couldn't be set in high-level plot() function
6: parameter "add" couldn't be set in high-level plot() function
Thanks for your help.

I think if you want to add a line (or superimpose a line) onto a plot you want
to use lines().
So what you want is:
plot( x, y )
lines( x, z )
If you want to add some texts, then use text(), legend() for a legend, title()
for axis labels/titles.
Hope this helps,

However, I was not asking how to use 'plot'. Instead, I was pointing out that the text of the help system is less than ideal in this case. Perhaps I am not expecting enough effort from the user, but it seems to me that the user should not have to read the "details" section on a second command in order to get the valid list of arguments for the first command, which in this case means finding out that about 1/3 of the 60 or so 'par' arguments are not valid for 'plot'. The help on "plot" could be changed to say something like "graphics parameters can be set from 'plot', except when they can't (for restrictions, see 'DETAILS' for 'par')", or "*some* graphics parameters can be set from 'plot'", but instead, it just indicates that graphics parameters can be set from 'plot'.

Thanks for all the responses.
FWIW, the par(new=TRUE) does rescale the graph as opposed to
lines(...) so it's more appropriate in the general case.
Yep, I do find the documentation rather terse.
For example, I haven't been able to rescale the axes properly.
I have 30 data points but I want the x-axis to read from 0 to 3000.
How is that done? What I've tried from looking at the ?axis
documentation does not work and then my y-axis is messed up.
TIA.
