SJava help
Hi, I installed SJava 0.66-1 on my linux RH 7.2 machine. I am using R-1.7.1. I set LD_LIBRARY_PATH up then called library(SJava) and it was fine. But when I called .JavaInit(), I got weird error that states it could not find java/lang/Hashtable. The session is below and shows my java configuration. I am using j2sdk1.4.2_01 from Sun. Thank you very much. Weiming Zhang > .javaConfig

error starting SJava: classpath
Dear R experts, Sorry, I am resending this, since I have not received this mail myself for the past 5 hours. I saw a similar question dated July 2. But there is no answer to it.

Here are the error message: > library(SJava) > .JavaInit()

SJava, Client X11
Hi, I have installed the SJava package (see http://www.omegahat.org/RSJava/ ) without any problem. I was able to run the examples (see http://www.omegahat.org/RSJava/examples/index.html ) from R, on my “R Linux server” and directly on the display of the server, But, if I run theses examples on an “X11 client”, under Linux or windows, with a “correct configuration” of the X11 client

R crashes with package SJava; was Memory leakage?
Dear all, Maybe this has something to do with R crashing? When my R version crashes, there is Rgui.exe still running in the background (i.e. W2K's task manager recognises it only as a process, which apparently is using almost 100% of the CPU). I can reproduce that by "using" the SJava package (from Brian Ripley's homepage, as suggested on http://www.omegahat.org/RSJava/).

mean and array
In general this is what "apply" does. In your example you could use rowMeans(ar) as well, I think.

save plot graph
Dear all, I have a lot plot graphs and i would like to save them. One solution is to use the grab function with xv. But it is tedious....

plot and bg
Hi all, I would like to plot some points and define the bg color of my graphics. But the bg parameter set is defined for the. whole graphic. In fact, i would like to use something like : box(bg=gray(0.9)). So, the background concerns only the plot region and not the main title, the x title and the y title. The option col for the function box() concerns the contour and there is no option

image with R
Hi all, i would like to analyze some images with R. For example, i have a tif image (16 bit=2^16 values) that i convert in ascii file (8 bit =256 values only) so it is easy to work under R with image() function. But, i would like to keep my image with 2^16 values... how can i do to load my tif image in my workspace? Do you know if there is a package for analysis image ? Thanks Olivier --
