Wish to install a local source package on Un*x platform from within R. Same thing as I can accomplish from cmdline as $ export R_LIBS=~/R/library $ cd /path/to/pkg $ R CMD INSTALL -l $R_LIBS <pkgname> So, how do you go about this anyway? And isn't this a bug in 'install.packages'? ------- $ R R : Copyright 2004, The R Foundation for Statistical Computing Version 1.9.0

Hi All, I've started work on a MetaPost device driver (please don't hold your breath). I've copied the XFig driver and renamed everything and this works, I can open the new metapost() and it works exactly like the xfig driver. Now all I have to do is the actual work! Just one question. There is a magic number in ExtEntries as follows: static const R_ExternalMethodDef ExtEntries[] =

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

Hi there, I want to create plots with some kind of 'complex' axis labelling of the form $\dot{V}$ and integrate those plots into a LaTeX document. What is the best way to go? I've figured out, that the 'plotmath' commands are somewhat limited (at least I wasn't able to get the $\dot{V}$ generated) and that plots with 'plotmath'-axes wouldn't export

Hello, The current xfig device lacks the functionality to set the textspecial flag and use the defaultfont in xfig. This is necessary when you want to export to xfig and use interpreted text (e.g., $ \frac{1}{e}$ gets interpreted by latex). The attached patch adds this functionality. Why would you like to do this? - Use math in labels (e.g., name your variables $r_{xy}$, do a

Is there a means to split a vector into its individual elements without going the brute-force route for arguments to a predefined function call? offred.rgb <- c(1, 0, 0) * 0.60; ## Brute force style offred.col <- rgb(offred.rgb[1], offred.rgb[2], offred.rgb[3], names = "offred") ## Desired style

Hy (I hope this is the right list). 1. Mac porting I'm finishing the porting of R for Mac. I hope to finish it for the end of september. Thanks to the porting of R 0.64 by Ross (that he gave me) I succeded in this porting. This is the current state: Both R 1.1.1. and 1.2.0 works with minor modification to the original code. The Macintosh device has been updated to the new version of

Anyone aware of tools available that can provide complexity metrics and/or code coverage analysis for R source? ---------------------------------------------------------- SIGSIG -- signature too long (core dumped)

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

Is there a canonical means to apply a function over multiple arrays simultaneously? For example, if I wanted to plot each line with a different color? Or is a for loop conversion my best option? x <- seq(0, 8, by = 2) y <- matrix(1:15, nrow = 5, byrow = TRUE) my.colors <- heat.colors(3) drawLines <- function(row) { lines(x, row) # want corresponding 'my.colors' here }

R 2.1.0/src/include from 2005/04/18 download Naming inconsistent for guards as well but that's pedantic. Simple convention: file <foo.h> #ifndef R_FOO_H file <R_ext/bar.h> #ifndef R_EXT_BAR_H Missing guards: <IOStuff.h> <Internal.h> <Parse.h> <R_ext/GraphicsBase.h> <R_ext/GraphicsDevice.h> <R_ext/GraphicsEngine.h>

Had been looking into Luke Tierney's R_AllocatePtr() and was left with a question about exactly when does R reclaim heap memory. Implication of 'simpleref.nw' is that one can allocate C data on the R heap, and as long as pointer object is alive, the data and pointer will remain valid. But it calls allocString() which is implemented using R_alloc(). 'Writing R Extensions" says

I'm translating some Matlab code and need some help figuring out how to change this call into an S4 generic method. In matlab, there's a function called 'repmat' with three calling sequences (all I have to deal with anyway): 1) B = repmat(A, m, n) 2) B = repmat(A, [m n]) 3) B = repmat(A, n) In all cases, A is the fill value, m is number of rows, and n is number of

I want the equivalent of this 'C' declaration. enum StoplightColor { green = 3, yellow = 5, red = 7 }; This mostly works except the validity checking doesn't seem to occur automatically. What didn't I do to enable it? setClass("stoplightColor", representation(value = "integer"), prototype = integer(1))

Needed to redefine function "sum" for my MATLAB package. There's something similar in Chambers's Green Book (pg 351) so I modified it as such: library(methods) setGeneric("sum", function(x, ..., na.rm = FALSE) { if (nDotArgs(...) > 0) sum(c(sum(x, na.rm = na.rm), sum(..., na.rm = na.rm))) else standardGeneric("sum") })

Hi This is for developers of extension packages that provide extra *graphics devices* for R. In the *development* version of R, support has been added to the graphics engine for sending raster images (bitmaps) to a graphics device. This consists mainly of two new device functions: dev_Raster() and dev_Cap(). The R_GE_version constant (in GraphicsEngine.h) has been bumped up to 6 as a

Hello, I have a few questions now: 1. How can I move data the following way: I have 2 variables: one two 1 5 ^ 3 4 | 1 3 | 4 4 | Now I want to move the two one arround (sorry I don't know how to say that in english). That means: I want to move the first item at the end of my column and move the second at the first place, the third at the second, and so on. You can see it at
