Hello R-help I am having trouble getting gls to find the R objects that comprise a linear model when the data=named.object option(option!) is not specified. In the gls() help it states data is "an optional data frame containing the variables named in model, correlation, weights, and subset. By default the variables are taken from the environment from which gls is called". An example:

Hello All I have just tried to install the ReadImages packge in R but am getting an error message stating: "This application has failedt to start because jpeg62.dll was not found. Re-installing the application may fix this problem" and at the R prompt this error message gets returned: > local({pkg <- select.list(sort(.packages(all.available = TRUE))) + if(nchar(pkg))

Hello list I am trying to use a Googlemaps tile (png file, 640 X 640 px tile) as a background to a plot and have been using the rgdal library to read in the PNG file (modified from code in the RGoogleMaps package). This works OK. My problem is is that the SGDF2PCT function in rgdal seems to be limited to 256 colors and this is introducing (I think) some degradation to the image which appears on

Hello I am using Sweave to generate some pdf reports using R on a Windows platform and would like to control the output directory that the generated .tex file goes to. Basically I use the following commands in a batch file: set outdir=c:/output/1234 Rscript -e Sweave('C:/pathpathpath/script.Rnw') Which produces script.tex Sweave has the option of specifying an output directory for

Hi R mailing list Does anyone know of a good way to conditionally evaluate R code chunks when Sweaveing? What I'd kind of like to be able to do is set a number of variables in a list and if variable.a=TRUE then process code chunk labelled "methodA", if variable.b=TRUE then process code chunk labelled "methodB" etc <<label=setvars>>= variable.a <- TRUE

Hello R help list I have been using the smoothScatter function within the "geneplotter" package to make some graphs using a Sweave Rnw script called via Rscript in a DOS/Windows batch file. The Rscript will ultimately be called by a web service with time-out constraints, hence things need to run as swiftly as possible. The geneplotter package is currently loaded each time R is invoked

Hello R-Help I have a question about the "behind the scenes" behaviour of the Rscript -e command and particularly its interaction with Sweave and tempdir(). We are trying to deploy R as a web service to do water quality analyses and have been writing software to call Sweave via Rscript eg: cmd> Rscript -e Sweave('sweavefile.Rnw') One problem we have been having is that

Hello R mailing list We are trying to use R and Sweave, running as a web service on a server to prepare statistical reports but are having problems with our anti-virus software apparently prohibiting execution due to what we think is Sweave trying to run an executable in one of the system's temporary folders. As background, we use the following Rscript command to invoke Sweave (the text in

Hi, I often use par(mex = 0.5) as an easy way to shrink space used for margins. However, I recently noticed that this leads to an asymmetry in the positioning of the x vs. y axis labels and xlab / ylab -- the x-axis labels are pushed into the tic-marks, while the y-axis labels look fine. A more extreme example: dev.new() par(mex=.1, mar=c(10,10,10,10)) plot(1:10) Tracking this down in the

Hello, I want to reduce the distance between my ticks and their labels. I managed to do it for the x-axis, but the y-axis puzzles me. Here's an example where there is no space between the x-asix ticks and labels. par(las=1) plot(runif(50), type="l",xaxt="n",yaxt="n",ylab="", bty="l") axis(2) axis(1,padj=-1.5) #However, axis(2,padj=-1.5)

Dear R-ians, I have a question concerning plotting different plots on one figure. I have written a script to plot an image, a legend (based on different rectangles) and a timeseries plot on one figure. In my R-lagnuage it looks like this (without arguments that are not usefull for my question): #---> I first define the functions image.data<-function(...){ .... #-->Plot the

Hi all, Quick question: What function can I use to draw a line in the margin of a plot? segments() and lines() both stop at the margin. In case the answer depends on exactly what I'm trying to do, see below. I'm using R v. 2.8.1 on Windows XP. Cheers, Alan I'm trying to make a horizontal barplot with a column of numbers on the right side. I'd like to put a line between the
