Dear all, I am using lapply to generate plots by applying a plot function to a list of dataframes. e.g. lapply(dataSet, FUN = plotFunction) Is there a way to call the list item number inside the plot function so that I can identify each graph? Thanks Chibisi [[alternative HTML version deleted]]

Dear all, Does anyone know how to overlay a 3d line on a wireframe plot? I would also like to be able to keep the legend that you get when using the option: drape = TRUE when using the option: shade = TRUE. In addition, I would like to know how to keep the axes while getting rid of the box, I use this: par.box = list(col = NA) to get rid of the box but that also causes the axes to disappear.

Dear all, I am trying to execute the simple example in snowfall http://cran.r-project.org/web/packages/snowfall/vignettes/snowfall.pdf ... require(snow) require(snowfall) sfInit( parallel=TRUE, cpus=2 ) sfLapply( 1:10, exp ) sfStop() I have installed the snow and snowfall packages in R on a machine with windows xp, however, after running the "sfInit( parallel=TRUE, cpus=2 )" line I

Hi all, I am trying to do a 3d plot where the x,y,z axes intersects with the origin (0,0,0) using the plot3d() funtion in the rgl package without success. I looked back at the past archives on this subject and someone suggested using djmrgl package. I searched and found it, installed it but when I try to load it I get the error ... Error in inDL(x, as.logical(local), as.logical(now), ...) :

Hi All, I would like to be able to use play3d() to translate the view along a surface, and zoom in and out. All the examples in play3d() function description are of rotations. I would also like to know if there is a method of creating a legend of for the 3d surface using rgl package. Thanks in advance. Chibisi [[alternative HTML version deleted]]

This works: class X def X.initialize( stuff ) end end X.initialize("bla") However stubbing it doesn,t: require ''test/unit'' require ''stubba'' class X def X.initialize( stuff ) end end class XTest < Test::Unit::TestCase def test_ X.stubs(:initialize).with("bla")

Hi guys, I was wondering why this piece of code doesn't work: foreach (i = c(1.25,1.50)) %dopar% { assign(paste("test_",i,sep=""),i) } but, this does: foreach (i = c(1.25,1.50)) %do% { assign(paste("test_",i,sep=""),i) } Obviously, the difference is %dopar% vs. %do%. If I use %do%, I get objects test_1.25 and test_1.50, but I don't get these

Hi folks, I'm trying to do something that seems like it should easy, but it apparently isn't. I have two large matrices, both containing a number of missing values at different cells. I would like to average these matrices, but the NAs are preventing me. I get a "non-numeric argument to binary operator" error. That's the first problem.

How can I identify the problem generating a warning in R CMD check for "Rd files with unknown encoding"? Google identified an email from John Fox with a reply from Brian Ripley about this last 12 Jun 2007. This suggests that I may have accidentally entered some possibly non-printing character into the offending Rd file. The message tells me which file, but I don't know

I have a very long list of strings. Each string actually contains multiple values separated by a semi-colon. I need to turn each string into a vector of the values delimited by the semi-colons. I know I can do this very laboriously by using loops, nchar, and substr, but it is terribly slow. Is there a basic R function that handles this situation? If not, is there perhaps a faster way to do it than

I was about to ask how to get this to work, but I think I might have solved it with another last look down the documentation before I clicked on the send button. I have an annoying little problem known as the iriver T60 audio player. It plays Ogg files from my PC perfectly well, but only in the same order in which it thinks they were copied onto its flash memory. It makes no attempt to sort

Hello, I would like to create a sequence of plots (using a for loop). I read in the FAQ that print() has to be used in order to obtain any output. This works perfectly fine as long as I only consider one function call in the loop, but I would like to add mtext() to the each plot in the loop. Unfortunately, this did not work. Any suggestions? As you can see from the provided example,

Dear useRs, Is there a way to 'properly' format %d when plotting more than one page on png()? 'Properly' means to me with leading 0s, so that the PNGs become easy to navigate in a file/image browser. Lacking a better solution I ended up using the code below, but would much prefer something like png("test_%d.png",bg="white",width=1000,height=700) where %d
