Hi, Here goes two plot questions I could not solve by myself: 1) I have a data frame with X (factors) and Y data, ordered by Y values. When I make plot(X,Y) x-axis is rearranged. How to keep the original order? To keep the original order (and to have points plotted, instead of horizontal lines) I tried, for X= names of 8 species and Y= median length:> par(lab = c(8, 5, 7)) > plot(Median,xaxt="n") > axis(side=1,labels=Species)But I had row numbers and not species names at x-axis. 2) In an interaction plot x-axis labels are overlapped. How to specify a step or frequency to x-axis labels? Here I tried to use xaxt="n" and axes=F and then replace the axis with axis(1, at=seq(0,100,10)) but I could not erase the x-axis labels. Thanks in advance.

I'd like to evaluate the fit of say an AR/VAR/ARMA model by examining the spectrum of the residuals. One observation I'd like to make is that with a certain model, 8% of the periodogram or smoothed periodogram values are outside the CI bound for white noise. How can I do this easily in R? thanks, Brian __________________________________________________ -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)
