Hi, I am a newbie with R, so I hope my question isn't too stupid. I am trying to generate dose-response curves using the "drfit" package. I have formatted my CSV files to the correct format, and have no trouble running drfit to get a summary of my data. The problem is that when I try to use "drplot" to graph my data I get an error. The message is: Error in

Dear Developers: I have a question about memory management in R 2.2.1 and am wondering if you would be kind enough to help me understand what is going on. (It has been a few years since I have done software development on Windows, so I apologize in advance if these are easy questions.) ------------- MY SYSTEM ------------- I am currently using R (version 2.2.1) on a PC running Windows 2000

Dear R Users, I am hoping you can help me. I have received code from a colleague who uses Matlab. I need to translate it into R. I am wondering if there is a randomization t-test (from non-parametric statistics) function already defined in R. (In Matlab the function is randtest.m.) ************************************************************************ ********** QUESTION: Is anyone

Dear Knowledgeable R Community Members, Please excuse my ignorance, I apologize in advance if this is an easy question, but I am a bit stumped and could use a little guidance. I have a finite mixture modeling problem -- for example, a 2-component gaussian mixture -- where the components have a large overlap, and I am trying to use the "mclust" package to solve this problem. I need

Greetings- I'm aware that there's no documentation for pictex available easily (that is, without purchasing it). I'm wondering if someone can help me with a simple task. When generating a plot using pictex() from R, one of the commands I use is mtext("Dimension 2: L=xxxx", side=2, line=3) when using X11(), this appears vertically along the Y axis; when using pictex(), it

Dear R-users It is me again with my interminables questions... This time it is about "pictex". I understood that pictex allows us to put our graph in a latex file I have try the function: > pictex (file=...) and the answer was: "pictex" not found... Does it mean that it is not an R-function yet? Thank you for any feedback. Halima from Leiden

Dear R People, I want to include a barplot corresponding to a simple discrete probability distribution in a LaTeX document. I decided to use the pictex driver. After a certain amount of messing about, I came up the stuff below. It does not look too bad, however, there is one very obvious piece of weirdness, ie. the y axis terminates at 0.1 and does not extend down further. I tried to adjust this

Greetings- I've got some plots I'd like to include in a LaTeX document; specifically, I'd like to include them via pictex() so I can edit some of the particulars directly. However, an odd problem is coming up: a diagonal line is drawn from bottom-left to upper-right when using pictex(). This does not happen using X11() or postscript() with the same series of commands. Any ideas why

Hi, I am very new to R and trying to bring my plot of residuals to my LaTex document, and seems as I need some help. I first tried the example from the help file, e.g. pictex(file="model1.tex", width=5, height=4) plot(1:11,(-5:5)^2, type='b', main="Simple Example Plot") dev.off() this worked fine in LaTex when I did : \centerline{\input{Rplots.tex}} However, with

Dear All, I'm trying to read a text data file that contains several records separated by a blank line. Each record starts with a row that contains it's ID and the number of rows for the records (two columns), then the data table itself, e.g. 123 5 89.1791 1.1024 90.5735 1.1024 92.5666 1.1024 95.0725 1.1024 101.2070 1.1024 321 3 60.1601 1.1024 64.8023 1.1024 70.0593

The example at ?pictex does not work (the driver apparently uses 'rotatebox') for me as stated. It did compile after including the graphicsx package. A MWE is at the help page for pictex. I tried to get in touch with Valerio but his email bounced. Probably we want to add a \usepackage{graphicsx} to the help page and try to track down Valerio. Cheers, Kyle This is pdfTeX, Version

[I'm refiling this one due to mailer config messup] I get an error whenever I try to plot a histogram in pictex. The error doesn't occur for X11 or postscript. > x<-c(1,2,3) > pictex() > hist(x) Error: Bad units specified in GConvert, please report! platform i686-unknown-linux arch i686 os linux

Hello, I got stuck with a graphics question: I've 3 figures that I present on a single page (window) via 'layout'. The layout is layout(matrix(c(1,1,2,3), 2, 2, byrow=TRUE)); so that the frst plot spans the both columns in row one. Now I'd like to magnify the fist figure so that it takes 20% more vertical space (i.e. more space for the y-axis). How would I do this in R?

I can't get LaTeX to recognize the output from the pictex device driver. Are these commands for some special latex package which I don't know about? ************************************************ * I.White * * ICAPB, University of Edinburgh * * Ashworth Laboratories, West Mains Road * * Edinburgh EH9 3JT

Dear All, I'm trying to draw a TeX histogram with the following pair of commands, pictex(file = "realhisto.tex") hist(Peaklist$V3,xlab="Height $z/\\ut{mm}$",ylab="Probability density $\\phi{}(z-z_0)/(1/\\ut{mm})$") However, in the resulting file realhisto.tex, I get, for example \put {Height \$z/\ut\{mm\}\$} [lB] <0.00pt,0.00pt> at 136.13 9.17 when

Hello, I'm trying to find out the optimal number of splits (mtry parameter) for a randomForest classification. The classification is binary and there are 32 explanatory variables (mostly factors with each up to 4 levels but also some numeric variables) and 575 cases. I've seen that although there are only 32 explanatory variables the best classification performance is reached when

Hello, I've a very long character array (>500k characters) that need to split by '\n' resulting in an array of about 60k numbers. The help on strsplit says to use perl=TRUE to get better formance, but still it takes several minutes to split this string. The massive string is the return value of a call to xmlElementsByTagName from the XML library and looks like this: ... 12345

I'm trying to use the pictex driver for bargraphs, and the shading isn't showing up. Is there any way to get some sort of shading in the plots? A hatch or stipple would be fine, too; just some way to differentiate the bars. The postscript driver won't do, since I'm trying to embed this in a LaTeX document which I'll use pdflatex on and \includegraphics for pdftex doesn't

Using "par" seems easily put a "hist" and a density side by side on the same output window. I would like to use some features in "histogram" from Lattice, but how can I put "histogram" and "densityplot" side by side on the same graph?
