I'm getting the following error when trying to execute a glm() procedure: Error in model.frame(formula, rownames, variables, varnames, extras, extranames, : invalid variable type for 'response' The commands I'm using to import the *.csv files, construct the data frame, and run the glm procedure are below: response <- read.csv("Response.csv",

I use model comparison with glms without mixed effects with anova(modelA,modelB), with mixed effects glm (glmmPQL), this doesn't work. Is there a way to compare model fits with glmmPQL's?

Hello, I'm wondering if there are any packages/functions that can perform conditional sequential gaussian simulation. I'm following an article written by Grunwald, Reddy, Prenger and Fisher 2007. Modeling of the spatial variability of biogeochemical soil properties in a freshwater ecosystem. Ecological Modelling 201: 521 - 535, and would like to explore this methodology.

Hi All, I am a PhD student in forestry science and I am working with LiDAR data set (huge data set). I am a brand-new in R and geostatistic (SORRY, my background it?s in forestry) but I wish improve my skill for improve myself. I wish to develop a methodology to processing a large data-set of points (typical in LiDAR) but there is a problem with memory. I had created a subsample data-base but

I'm trying to generate a sequence of random integer values. I've tried to combine the random (r) and the sequence (seq) functions but this approach does not work. For example, if I use the following command: > a <- seq(1:100) > a [1] 1 2 3 4 5 6 7 8 9 etc. This is a good start, but what I really want is something that would look like this instead [1] 3

Does anybody know how to get a pdf file with landscape orientation?. pdf(file= 'my_file.pdf' ,onefile=T,paper='A4') plot(sin, -pi, 2*pi) dev.off() Thank's in advance Juan A. Hernandez Spain [[alternative HTML version deleted]]

Hello together! How can I plot a landscape letter-format plot? With postscript, I just use the horizontal option and I get what I want, but it seems that the pdf lacks this option. Well, I could do a ps2pdf conversion of the generated ps-file. But is there a way to directly produce landscape pdf-plots with R? Thanks for any help. Greetings, Sebastian

Is there a set of R expressions that has the same effect as the following set of S-Plus 2000 expressions: graphsheet(format="printer", orientation="landscape") par(mfrow=c(2,2)) plot(x1, y1) plot(x2, y2) plot(x3, y3) plot(x4, y4) dev.off() # one page of landscape plots sent to printer I am having trouble with formulating the equivalent of the first line of the above in R.

Hello listers, I would like to know how I can get the resulting graphic of the function plot.hclust (from the package cluster) in landscape orientation. Is it possible? Thanks, Juan

Hi, I made a few graphs by ggplot. The following codes produce a pdf file with graphs in landscape orientation on my Windows PC, while they produce a pdf file with the same graphs, but in portrait orientation: *p2 <- lapply(1:(2*n), function(.x) xyz_outl[.x][[1]]) #a sequence of graphs made by ggplot* *m2 <- marrangeGrob(p2, nrow=3, ncol=2) * *ggsave("xyz.pdf", m2)*

This is a windows-specific question. After generating a plot, I can print from scripts or the command line with > dev.print(win.print,printer="local windows printer name") I would like to print in landscape mode. From the menus, I can accomplish this by changing the properties of the printer before clicking "print". However, I tried adding

Hi: I am haviong problems with Landscape mode on our HP printers (many models). I am running 2.2.7a on two different servers. One is using the "old style" printing (using "printer driver file" parameter). The other is using the newer printing system. It is the same code on both. Both are Solaris systems. For the old one, the drivers are installed on the client, for the

R Users, I have created a multipage PostScript file using the postscript() function with horizontal = TRUE to produce my plots in landscape. I intended to convert that entire file to PDF using ps2pdf to have the plots available for a presentation. Unfortunately, the resulting PDF document is rotated -90 degrees. I have found dozens of references to this kind of problem with ps2pdf online, but

Dear all: Does anyone have any suggestions on how to make a spatially explicit landscape with spatial autocorrelation in R? In other words, a landscape where all cells have a spatial reference, and the environment values that are closer in space are more similar (positive spatial autocorrelation). Thank you, Laura

Dear all: I would like to create a landscape of environmental values that follow a uniform frequency distribution and also have spatial autocorrelation in the landscape. I was wondering if there is an algorithm and/or package out there that creates autocorrelation of values that are distributed according to a non-normal frequency distribution. Any suggestions are greatly appreciated. Thank you,

Hello All, I 'm trying to plot R graph in landscape orientation in a .rtf file. i 'm using library(rtf) for this. do we have any option in addPlot() function to rotate the orientation of the rtf file?

Dear list, I'm stuck with a little graphical problem. I'm generating several lattice plots which are printed in a single postcript device opened by > trellis.device(postscript, theme=canonical.theme("postscript", color=F), file="an_phase2_graph.ps", paper="a4", pointsize = 10, onefile=TRUE, horizontal=TRUE) Everything works fine,but some of these

Dear R users, Thanks in advance. I am Deb, Statistician at NSW Department of Commerce, Sydney. I am using R 2.8.1 on Windows XP. I like to save Trellis Plots on A3 size paper (Portrait and Landscape). Currently, I am using the following command to save a Trellis Plot in pdf [This is an example code]: pdf("D:/Analysis/test.pdf") dataFile <- expand.grid(xo=

Hi! I have browsed the help archives but did not find anything on the subject: How to make publication quality graphs with R best? Is there some document about that topic out there? The problem is that the graphs look nice on the screen but when printed in black and white every color apart from black doesn't look very nice. Is there some guideline how to set color palettes and or fill

Dear R-users I am trying to understand how Sweave works by running some simple examples. In the example I am working with there is a chunk where the R-commands related to plotting a figure are placed. When running R CMD Sweave ? , pdflatex the output is a portrait figure. I wonder whether it would be possible to change the orientation to landscape (not in the latex file but in Rnw file). Many
