Hi, In SPlus there is a function called "twoway" for median polishing gridded data. Is there an equivalent function in R? I have been searching for it in R help without much success. Your help is much appreciated. Cheers Sorn [[alternative HTML version deleted]]

Hi all, I've been trying to run Sweave with R code embedded - using the ggplot2 package and in particular the qplot command. There appears to be a problem in Sweave not picking up that qplot is a function. Has anybody else tried to use qplot in Sweave and have you been successful? Any help would be very much appreciated. Kind Regards, Sorn Notice: This email and any attachments may

Hi there, I'm a bit confused concerning the axis tck setting in the lattice package as the ticks on left sided axis aren't drawn at all with the following setting: dados <- data.frame(varsep = factor(rep(1:2,10)), i = runif(20)) library(lattice) my.theme <- list( axis.components = list(left = list(tck = 1, pad1 = 1, pad2 = 2), top = list(tck = 0, pad1

Dear all, We are trying to fit a non linear model to dispersal data. It seems that sometimes when the fit of the model of the data is not very good we start getting singular gradient errors. However if we modify slightly the data this won't occurr. We have also tried changing the initial parameter values and the algorithm for fitting in nls but didn't help. So we ended up programming a
