similar to: R-beta: Re: S Compatibility

There needs to be more recognition in the academic community of the importance of contributions to widely used software. While many organizations are encouraging software development if it generates revenue, it is harder to measure the value of software that you give away. It is often hard to measure the number of users, so unless they mention you in citations, there is little hard evidence to

Thanks to Ross Ihaka and Bob Wheeler for responding to my earlier question. I looked into the Johnson system functions in SuppDists package. For now, I want to stick with the density(...) estimator, and so still need the variate lookup function. As per Ross' suggestion, I just did a numerical integration on the density object and used approxfun/splinefun to "lookup" the variate

Hi, I'm trying to install rimage on a Mac OS X 10.4 machine. I followed the advice in previous R-help threads and got over the hurdles of having the header files in the right places, among other things. But I can't figure out what to do with this error. ice.pnl.gov:/home/waichler<949>system_profiler -detailLevel mini SPSoftwareDataType Software: System Software Overview:

How can I access examples of trellis graphs in R? I'm especially interested in getting code for xyplot() examples. Failing a collection of examples in R, I see that under Splus there are numerous example.*() functions. I can access Splus with a command line but can't open a graphics window, so I can't to execute the example.*() functions. Is there a way I could get the associated

I have the same question that Eusebio had: Is there a function similar to "sink" that redirect also R code to a file that is: sink("R001") x <- c(2,-6,-4,8,5,4,1,3,4,-9,0,1) A <- matrix(x, ncol=3) A A.prima <- t(A) A.prima dim(A) dim(A.prima) sink() create a file "R001" with contents: ------------------------------------------ [,1] [,2] [,3] [1,]

I frequently use Makefiles to manage routine data manipulations and repeated analyses where the "raw" data tend to change with time. With S/Splus, this has worked quite naturally, as long as I'm careful to use S object names that map directly to Unix/Linux filenames. For example, say I'm building a particular graphic (chart.ps) from a data.frame in S (mydata) that comes from an

Hi folks: Is there a lookup function that returns the variate given the cumulative probability for an object returned by the density(...) function? > mydata _ as.vector(mymatrix) > mydata.density _ density(mydata) > mydata.p80 _ lookup(mydata.density, p=0.8) # is there any function to accomplish this task?

I am using levelplot() from lattice with grids that have unequal cell sizes. This means that the boundary between two cells is not always half-way between nodes, as levelplot() assumes. The result is that some cell sizes are rendered incorrectly, which can be painfully obvious if using relatively large cells. Is there any work-around? I am using the conditioning capability of lattice and

Members of R-devel may be interested in the special Sept. 2000 issue of J. of Comp. and Graph. Statist. http://www.amstat.org/publications/asajournals.html#jcgs on Systems and Languages.

I would like to use a map or aerial photo as a background to plotting solid lines and text, and semi-transparent color contours, in base and lattice graphics. Plot coordinates need to be consistent with the georeferenced background. For example, a color contour plot would have an gray-toned aerial photograph as a background for overprinted semi-transparent color contours of some spatially

I can't get Emacs to automatically do syntax highlighting of Sweave files. I have followed Friedrich's suggestion for code to insert into my .emacs file. The complete section from my .emacs file is given below. When I load a *.Snw file, font is white until I press M-x, then the first code and document chunks get highlighted, but not the rest of the file. Latex and Noweb menus are
