Oh sorry. An example say lots more than words. The data below, when submitted to twoord.plot return the mentioned error. Rain are bars and Salt lines, the bars appear and the error occurs with the salt data.
If you get an error complaining about needing finite ylim values,
then why not supply them?
This worked for me (after fixing your data which contains
several commas where decimal points are needed) and calling
the data frame 'd':
with(d,
twoord.plot(
lx=1:14, ly=Rain, rx=1:14, ry=Salt,
lylim=c(0,450), rylim=c(0,20),
type=c('bar','b')))
(I had to use with(), because the 'data' argument
in twoord.plot seems not to function as intended.)
I have no idea why anyone would want to use a barplot
for the Rain data, but ...
The above should not be taken as an endorsement of
the production of abominable plots (to which, however,
I am becoming inured).

If that does not work, then send a small reproducible example (the dput command is great for the data part) which will help us find the problem. -- Gregory (Greg) L.

-----Original Message----- From: Rodrigo Aluizio [mailto:r.aluizio at gmail.com] Sent: Thursday, December 09, 2010 12:27 PM To: Greg Snow; 'R Help' Subject: RES: [R] Barplot with "Independent" Lines Y axis Thank you for the function suggestion, works nicely for complete data vectors. Just another question. When using the twoord.plot I reached another issue, it seems that this function can't handle NAs in one of the variables (the data of one month for another variable is missing). The lines and barplot functions just interrupt the plot and continue after the NA but twoord.plot gives me an error: Error at plot.window(...) : finite values are necessary for 'ylim' Is there a way to work around this error? P.S.: I'm aware of the problems regarding this type of graph, but this time it's not a choice of mine (unfortunately). Thank you anyway for the highlight, maybe it will help me arguing.
