Well, at least I could help (even if unintentionally), as a compensation for all the help I got from the list. Cheers.

Re: [R] RES: Barplot with "Independent" Lines Y axis
Hi: Like Peter Ehlers, I'm not a big fan of multiple response variables on a page with different y-axis scaling, but if you have to do it, try not to let one graphical metaphor interfere with/obscure/dominate the other (e.g., bars and lines). This is my attempt, both with connecting lines and points, but am holding my nose in the process: library(plotrix) dd <- read.table(textConnection(" Point RainSalt Fev/03 365.6 13 Mar/03 235 18 Abr/03 115.1 18 Mai/03 47.418.75 Jun/03 112 15 Jul/03 156.8 17 Ago/03 66.115 Set/03 149.8 14 Out/03 167.1 11.5 Nov/03 269.3 17.5 Dez/03 283.7 NA Jan/04 415 1.3 Fev/04 322 8.5 Mar/04 258.7 10.5"), header = TRUE, stringsAsFactors = FALSE) closeAllConnections() dd$mo <- seq(nrow(dd)) with(dd, twoord.plot(lx = mo, ly = Rain, rx = mo, ry = Salt, lylim = c(0, 450), rylim = c(0, 20), lcol = 'red', rcol = 'blue', lpch = 1, rpch = 16, type = c('b', 'b'), xtickpos = mo, xticklab = Point) ) legend('bottomleft', leg = c('Rain (left axis)', 'Salt (right axis)'), text.col = c('red', 'blue'), col = c('red', 'blue'), lty = c(1, 1) ) I understand why these types of plots exist in general, and I can see why you might want to compare two variables that are temporally related but have different units of measurement, but by doing so, you are increasing the cognitive task of the average viewer.

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.)

[R] RES: 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.
