Hi, Found the answer to the background myself: 'trellis.par.get' and 'trellis.par.set' background<-trellis.par.get("background") background$col<-"white" trellis.par.set("background", background) Willem -- Dr R.W. Vervoort McCaughey Senior Lecturer Hydrology and Catchment Management...

Hi Silly question maybe, but I am only a novice. How do I make the background of contourplot white? I have tried bg, canvas, and all other possible option suggested under par and xyplot. But nothing seems to work. Since...

Dear all, I am struggling to understand this. What happens when you raise a negative value to a power and the result is a very large number? B [1] 47.73092 > -51^B [1] -3.190824e+81 # seems fine # now...

Hi all, I am trying to do an inversion of electromagnetic data with non-negative least squares method (Tikhonov regularisation) and have got it programmed in S-Plus. However I am trying to move all my scripts from S-Plus...

Dear all, I am not sure what I am doing wrong, but I have some unexplained behaviour when saving a lattice graph including text to a pdf file. The text seems to move around. It must have something to do...

Dear R-help list, I am trying to construct a lattice histogram using 3 factors. My dataframe looks like this: (simulating a waterbalance over groundwater with different salinities) s days model EC EC_max 0.4 1 "A" 10 9...

Hi all, IN the end the page() function was what I wanted. I was using levelplot in the actual code and I wanted different text in each of the panels. That was only possible with the paeg function or with...

Hi Uwe, I should send these messages from my member e-mail number Thanks for that. As you can see from the last bit of my code, I tried that, but it gave the same results. I had a look...

Thanks for all the points. Riding my bike back home I realised that the fractional power was a problem. I also forgot about the operator precedence: > b <- 48.3 > -53.1^b [1] -2.099256e+83 > (-53.1)^b [1...

Hi I think I have been struggling to use replace correctly, I usually work my way around this using a loop, but I think this is in fact inefficient. I have a dataset with runoff from three plots and associated...
