Hello, Just look at the examples in ?persp. There is a function called trans3d defined in it that will traduce your 3D coordinates to 2D, and so you will be able to draw lines with lines function.

Dear wizaRds, I use the MASS::kde2d function to estimate density of the two first principal components. I do that to have a graphic visualisation of a "group structure" in my dataset. So far, no problem. But i would like to estimate that density using weights according to the COS?? values that tells me if my observation is well represented on the factorial plan 1-2. I would like to

Hello list, I'd like to know if there is a function that tells in which package is a given function. Something like : which.package("lda") [1] "MASS" Thank you.

Hello all, It seems that the next improvement to the R Graph Gallery is categorization of the graphics, that way each graph will be easier to find. That step should be done *carefully* if we want to avoid the opposite side-effect : graph not reachable through the categories. That's why the wisdom of the R community is required. Graphics will be classified in : - categories -

Hello useRs and helpRs, Some time ago, in a gallaxy far away (here is the thread : http://finzi.psych.upenn.edu/R/Rhelp02a/archive/46532.html ) we discussed about a graph gallery showing the power of R in that domain. I did some work around that, and there is a (pretty advanced) draft here : http://addictedtor.free.fr/graphiques/displayGallery.php For instance, there are some of my graphs,

Hi, this is to announce a new version (1.1-2) of my package fpc. Apart from the stuff already present in the older version (methods for fixed point clustering and clusterwise regression, somewhat bug-cleaned and with faster examples) there is now a function cluster.stats, which computes some distance-based statistics often used for cluster validation, description and decision about the number of

Hi list, I'm updating my fpc package at the moment and will add some new functions. I learned that there should be print and summary methods for the key functions. The purpose of the summary methods seems to be to reduce the possibly incredibly complex information in the function's output and the print method (print.summary.foo) should print an overview of the result. But in some

Hi Everyone, We want to use the rsync 3 for incremental file transfer of our File system from one box to another, however there are about a million files to be copied, so just wanted to know by any one of your's previous experience with rsync 3, will these many files get copied at first time and incrementally in the subsequent run of the crontab. Replies will be much appreciated. Thanks in

Hi, I have a mac OS X 10.4.11. Since I have updated R (version 2.6.2) I have a bug with the console:=20=20 when R is busy and I want to stop the computation, I click on "STOP"=20=20 and then R does not respond anymore (I have to kill it). I had no=20=20 problem with my previous version. For information, I have downloaded R-2.6.2-mini.dmg regards, Christophe. --- Ma=EEtre de

Hi, I'm just getting started with R and I'm having problems with some simple operations: I want to get the the sum of the column "SStot" for each year using the function by. The data set is named "SS". I've tried this: by (SS, year, sum(SStot)) and it's not working. Is it because there's a different number of rows for each year? How else can I do

I can't seem to be able to change the font size in an effect display. I've tried the following: > par(cex.lab=4) > plot(effect ("alti",reg8), ylab="detection probability") and > plot(effect ("alti",reg8), ylab="detection probability", cex=4) but nothing changes. Can anyone help me? thanks. Emilie Berthiaume graduate student

Howdee, *** I know that the lmList() function exists, yet I don't want to use it. *** Would anyone be kind enough to tell how I can apply the function lm() to each level of a given factor so to obtain the intercept and slope for each factor level within a matrix? For instance, suppose a dataframe containing 3 variables: id, x and y. I want to compute the function lm() for each level

Howdee, My question appears at #6 below: 1. I want to model the growth of each of a large number of individuals using a 4-parameter logistic growth curve. 2. nlme does not converge with the random structure that I want to use. 3. nlsList does not converge for some individuals. 4. I decided to go around nlsList using: t(sapply(split(data, list(data$id)), function(subd){coef(nls(mass ~

rendercheck -f a8r8g8b8 passes as much as on a GK208, and xv appears to work. Very lightly tested. Instead of sticking coordinates into pushbufs, the vertex shader is modified to read them from a constbuf, indexed by vertex id. This approach could be used for all nvc0 generations, but I didn't want to rock the boat. Signed-off-by: Ilia Mirkin <imirkin at alum.mit.edu> ---

Hi, i've just installed vmware 5.5 on a win2k SP4 machine, and i've installed a Suse 10.1 on the virtual machine. actually i'm using *only* the command line interface on linux, my goal is only to be able to compile the C++ source files i have on my windows partition with gcc on linux. in order to do this, i need to mount my windows partition in my linux, and i need to be able to
