Open-source Languages & Tools for z/OS

Hello,

I’d like to install R packages I got from CRAN repository, for example, RJDBC.

First, I tried to install rJava package because it is required for RJDBC.

I get rJava_0.9-8.tar.gz from CRAN site and upload to z/OS USS.
https://cran.r-project.org/web/packages/rJava/index.html

And then I issued install command but failed.

$ R -e 'install.packages(c("rJava_0.9-8.tar.gz"), repos = NULL, type="source")'

How can I insatall R packages?

Hello Tomohiro,

It might be difficult to get everything working that you will need to install R packages that include C or C++ code. But le us see how far we can get.

Can you please send us the file config.log?

thanks,

Rick Harris

Hello,

It seems that config.log file was created in /tmp directory, such as /tmp/Rtmp3I0Jcq/…, but this directory was removed after package install command.
Do you have any idea for checking config.log file?

regards.

Hello,
I predict a series of little problems. I will certainly port this module
sometime in the next week or three, if you would prefer to wait.

Anyway here is a useful bit of R code:
all_packages <- c(“rJava”)
uninstalled_packages <- setdiff(all_packages,
rownames(installed.packages()))
if (length(uninstalled_packages) > 0) {
install.packages(uninstalled_packages, type = “source”, repos=“
http://cran.rstudio.com/”,
destdir="/u/pdharr/Rnew/downloads", INSTALL_opts="–verbose
–no-clean-on-error")
}

regards,
Rick Harris

Hello,
Thank you for your support.

I tried install with --no-clean-on-error option like following but it seems config.log was removed.

install.packages(c("rJava_0.9-8.tar.gz"), repos = NULL, type="source", destdir="/u/cics004/R/package/dest",INSTALL_opts="--verbose --no-clean-on-error")

(I couldn’t find config.log even though I issued “find / -name config.log” command.)

And our z/OS environment can not access external web sites directly such as http://cran.rstudio.com, so I have to download files by PC and transfer them to z/OS.

I’m looking forward your updates!

regards.
