[R] Using only one grid direction in filled.contour.

I have a 3 dimensional plot using filled.contour. Normally the function provides a grid or wire plot with lines referencing the y and x axis values. Is there a way to use only one direction, say the y or x only? I'm not sure this helps, but it would be similar to plotting data in a 2 dimensi

[R] Altering the cube around a wireframe plot.

perspective=FALSE, zlab=list(label=expression(lb[f]), just=-1), par.box = list(col=c(1,1,NA,1,1,NA,1,1,1))) I found that the par.box option controls multiple lines in the plot not just one at a time. I have made some attempts at adding lines to the plot to put profile plots on the 'back wal

[R] Covariance structure determination when lmer has false convergence.

e two likelihoods or the AIC or BIC to compare the two model since the one model had false convergence. Is this correct? If so, what would be a good approach to comparing the two models to validate the smaller model? Thanks for the time. Todd Remund [[alternative HTML version de

[R] The function ksmooth(), is it a bad algorithm or just a slow function?

I noticed that the ksmooth documentation mentions the function is real slow and that better smoothing functions are available. Does this mean that the method itself is a poor method for smoothing data or just a slow function? Thanks. [[alternative HTML version deleted]] __

[R] Using the Arial font in the plot function.

I would like to ensure that all the text in my plot is in the arial font, like in excel and word. I have been saving my graphics to a file using the png() function, and have tried the postscript() function. In the documentation I have not been able to find a way of changing the family argumen

[R] Wisker lty change in bwplot.

Is there a way of changing the line type for the wiskers in bwplot? I have been able to do pretty much everything I would like to do in bwplot, just can't change these lines from dashed to solid. Thanks. Todd Remund [[alternative HTML version de

[R] Device problems in a loop.

I have tried the following code to plot and save many box plots in files. The code works by itself, but does not run in a loop. The error indicates that there is no device. The error is printed below the code. Code: for(i in 1:len) { A = as.numeric(delta[Delta[i,1]]) B = as.numeric(

[R] Simulate ARX model.

the package dse1, but I am unsure as to what type of TSmodel to create to put into it. Could anyone give me some hints? Thanks. Todd Remund [[alternative HTML version deleted]] __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman

[R] Axes limits in rgl.surface.

I have looked through the documentation and have not been able to find a way of using an xlim, ylim, or zlim type option on rgl.surface. I know that persp3d has the option, but seems to only be able to expand the axes not reduce them. Is there anyone who has an idea of how to do this? Thank

[R] Frequency and Phase Spectrograms

I know that there is a function, (spectro3D), that produces the Power Spectrogram. Are there R functions that produce the Frequency Spectrogram and the Phase Spectrogram? Thank you for your time. [[alternative HTML version deleted]] __ R-hel
