similar to: pass an array of array from Java to R- Rserve

Hello All, I am trying to get cluster heatmaps using R from Java in my application. I got the Rserve using which I am able to make TCP/IP connection to R. I am trying to send a double[][] array (say 5x8 dimensions) to R and convert it into matrix using as.matrix() function in R. Is it correct to do this? Can I directly pass this array to dist() function to generate the distance matrix ? if not

Hi, I have a tab seperated file with 206 rows and 30 columns. I read in the file into R using read.table() function. I checked the dim() of the data frame created in R, it had only 103 rows (exactly half), 30 columns. Then I tried reading in the file using read.delim() function and this time the dim() showed to be 206 rows, 30 columns as expected. Reading the read.table() R-help documentation, I

Hello R users, Good day!! I was wondering if there is a way in R to read in a particular column from a tab-delimited file, edit it and write it back into the file with all other columns intact. When I say edit I mean just replacing all the values in that column. I know to read a particular column from a file using colClasses option in read.delim() function. Is there any such option to write out

Hi All, I am trying to import a .sas7bdat file into R. I tried using Hmisc package's sasxport.get() function. temp <- sasxport.get("path\abcd.sas7bdat") I get an error that says "Error in lookup.xport(file) : file not in SAS transfer format" I am not familiar with SAS transfer format. Could somebody please clarify what is it that I am missing, Thanks for your

Hi, there: As you all know, correlation is not a very robust procedure. Sometimes correlation could be driven by a few outliers. There are a few ways to improve the robustness of correlation (pearson correlation), either by outlier removal procedure, or resampling technique. I am wondering if there is any R package or R code that have incorporated outlier removal or resampling procedure in

Hi All, I am trying to install ncdf package on a Linux 64-bit machine. I successfully installed netcdf using this command, ./configure --prefix=/home/challar/netcdf/ --disable-netcdf4 I then tried to install ncdf package in R R CMD INSTALL --configure-args="-with-netcdf_incdir=/home/challar/netcdf/include -with-netcdf_libdir=/home/challar/netcdf/lib" ncdf_1.6.3.tar.gz I get this

Dear all, I am interested to calculate confidence interval for fitted values in general for non-linear regressions. Lets say we have y=f(x1,x2,..xN) where f() is a non-linear regression. I would like to calculate a confidence interval for new prediction f(a1,..,aN). I am aware of techniques for calculating confidence intervals for coeffiecients in specific non-linear regressions and with them

I wrote some code which reads a gzipped text file directly from the web with gzcon(url()) and it works perfectly on OSX, but I cannot get it to work on linux at all, trying several different R versions and linux distributions.

Hello, We are facing some problem while calling a Rserve API from our Java client. The details are as below: 1) We have installed Rserve on linux machine "Nagarajan"(Port: 6311) and related modules. 2) We have started the Rserve in daemon mode perfectly by executing the comman " R CMD Rserve" on the linux machine. But when the Java client executes the statement:

Hi, I have also tried to install the Rserve package on my machine. I am able to load with with library(Rserve), but when I trype Rserve() to start the server, I get the following message: > Rserve() Stating Rserve...

Hi, I am trying to install Rserve 1.7-0 on CentOS 6. But I get this compilation error - /usr/lib64/Revo-5.0/R-2.13.2/lib64/R/lib/libiomp5.so: undefined reference to `pthread_atfork' I tried other versions of Rserve (0.6-5 and 0.6-8) without any success. How do I get around this issue? My goal is to run FastRWeb (which uses Rserve). Thanks in advance. Joydeep. -- View this message in

We had something similar, and as far as I recall the problem turned out to be that we had not set the config file to allow remote connections. This would probably be better put on the Rosuda mailing list: http://mailman.rz.uni-augsburg.de/mailman/listinfo/stats-rosuda-devel Hope this helps, Matt Wiener -----Original Message----- From: r-help-bounces at stat.math.ethz.ch [mailto:r-help-bounces
