Hi R Expert Community, I need your help in getting rggobi and ggobi to work. I tried running ggobi under Rattle's Explore tab and interactive option but got an error. I then tested library('rggobi')and noticed I get the same error. So it's not Rattle specific. I have GGOBI and rggobi installed on my machine. Below is the info. At first I got Error 'A' below. Then I

Hi, I want to get a clean succinct list of all levels for all my factor variables. I have a dataframe that's something like #1 below. This is just an example subset of my data and my actual dataset has 70 variables. I know how to narrow down my list of variables to just my factor variables by using #2 below (thanks to Bert Gunter). I can also get list of all levels for all my factor

Gracias Jorge por contestar tan rápido. Con gdata hago eso del path, y directamente con el fichero, lo vi en una web, y he intentado todas las opcioens que he visto. En vez de install.packages('rJava', type = 'source') he hecho install.packages('rJava') Ahora probaré, y lo mismo con scan y readLines. He visto en stackoverflow que mi problema puede ser actualizar java,

Dear All, I think there is something wrong with rJava on any Debian based distribution. I may be wrong, but I experiencing exactly the problems mentioned at https://github.com/amattioc/SDMX/issues/130 and at https://github.com/s-u/rJava/issues/110 A couple of packages (RJSDMX and xlsx) are now impossible to install on my debian stretch platform running R 3.4. It seems I am not the only one

Hi Hilmar, weird. The memory problem seems be due to recursion (my R, version 3.3.3, says: Error: evaluation nested too deeply: infinite recursion / options(expressions=)?, just write traceback() to see how it happens), but why does it segfault with xlsx? Nb xlsx is the culprit: neither rJava nor xlsxjars cause the problem. On the other hand, quick googling for r+xlsx+segfault returns tons of

I am not a Mac user, but I do use Linux and I would recommend not running R with sudo unless you are an admin ninja. That defensive practice would render the answer to your question moot. It is possible that your problem may have started with inappropriate use of sudo in configuring java, but configuring Java is not on-topic here. -- Sent from my phone. Please excuse my brevity.

Hi! I?m on macOS 10.13.3 and just installed the new Java 10 using Homebrew Cask. I also have installed R with Homebrew. Everything seems to work fine, however I just get different outputs if I run sudo R CMD javareconf or R CMD javareconf. With sudo I get pointed to Java 9 and without sudo I get pointed to Java 10. I really don?t know why. Without sudo: $ R CMD javareconf

Hi Dirk, It was unclear to me to which extent it is a kernel/security patch vs (r)Java issue. In any case, this is really problematic for me as it prevents me de facto from running some key R packages for my daily work. I'll post again if I see some solution (other than downgrading the kernel) somewhere. Meanwhile, any suggestions for a fix is welcome. Cheers Lorenzo On Mon, Jun 26, 2017

Hola, @javier, me gustaría no tener que hacer nada de forma manual, ni por fuera de r, rstudio. Es decir, el típico comando de linux que me convierta de xls a csv prefiero no usarlo. Me gustaría hacerlo todo desde R. @jorge -> Con RODBC me salta -> Error: could not find function "odbcConnectExcel" Lo que creo que es inevitable en Ubuntu

Dear devel-listers, I found a conflct between rJava and data.table. Actually me questions is where to report it? Should I rather send it directly to the package maintainers or post it on some bug tracker. The problem is that data.table has a function called "J" and rJava uses the same quite intensively. I used the xlsx R package which depends on rJava to write .xls files and ran

Hi Jeff!! I really don?t know if running R CMD javareconf with sudo has posed a problem here, now or in the past. What I know is sometimes it?s the only way to really config it, if I don?t run with sudo, in the end it asks me if I want to overwrite the configuration from root override rw-r--r-- root/admin for /usr/local/Cellar/r/3.4.4/lib/R/etc/Makeconf? (y/n [n]) y override rw-r--r--
