Hi, I'm doing a k-means cluster with 6 clusters and 15 variables. Any suggestions on how to plot the results? I've tried the standard xy plot, but couldn't get much of it. Thansk in advance, Iuri.

A client of mine has a ton of data stored in Excel spreadsheets. I''m building a web application for her (backed by a real db of course) and want to import all that data. Is there a library available to read data from Excel? Is there an easy way to upload the spreadsheets and then read the data? Thanks, Ken Kousen -- Kenneth A. Kousen, Ph.D. President Kousen IT, Inc.

I am desperate for help. I am trying to get the RJDBC and rJava .5to work on both my windows xp and linux Redhat EL5 Server. On both I get a ava.lang.ClassNotFoundException when calling JDBC(). My example is require(RJDBC) classPath='C:\\libraries\\mysql-connector-java-5.1.3-rc\\mysql-connector-java-5.1.3-rc-bin.jar' driverClass=c("com.mysql.jdbc.Driver") drv <-

Is it possible to output via ROR from a db to a POI file ready for inclusion in a satellite navigation program like Tomtom?

Craig, Thanks for your follow-up note on using the asypow package. My problem was not only constructing the "constraints" vector but, for my particular situation (Poisson regression, two groups, sample sizes of (1081,3180), I get very different results using asypow package compared to my other (home grown) approaches. library(asypow) pois.mean<-c(0.0065,0.0003) info.pois <- info.poisson.kgroup(pois.mean, group.size=c(1081,3180)) constraints <- matrix(...

Hi all, I've got kind of strange setup, wherein all of my data is on a big NFS server (RH linux 8.0 running the 2.4.18 kernel and nfs-utils 1.0.1-2.80) and my Samba 3.0.0 PDC server (RH linux 7.3 w/ 2.4.18 kernel, nfs-utils 0.3.3-6.73) mounts the NFS export with the following options: rw,vers=3,wsize=8192,rsize=8192,hard,intr This mounted partition is then re-exported to the windows users

Hi, I need to read in some data from an excel file. After spending a while looking around, POI for ruby looks like the best solution. However, it misses support documents for newBs like me. I wonder if anyone here has done that before and wants to share a little bit of the information. Please help.

Hi, I am trying to implement a scenario similar to running ExceptionDemo.cpp with parameter -1 (where the JITed code calls the C++ function which throws an exception) Different from the given example I am using IRParser instead of IRBuilder. I can successfully catch the exception in Linux but the program crashes in Mac and Windows. The code is similar to as follows: ### The test.cpp :

Hi, I am stuck in a looping problem. It might be an easy problem for experienced R users but I have been unable to do it. Any kind of help or advice will be great appreciated. I am creating a spatial grid and have a list of spatial points in a folder. I can read the spatial points separately and get a count of the points in the spatial grid in R. The output should be a table showing the counts of

Hello, I have a 32 GB RAM Mac Pro with a 2*2.4 GHz quad core processor and 2TB storage. Despite this having so much memory, I am not able to get R to utilize much more than 3 GBs. Some of my scripts take hours to run but I would think they would be much faster if more memory is utilized. How do I optimize the memory usage on R by my Mac Pro? Thank you!
