Hi,
I tried to install some R packages in R, and encountered a problem which might be the interaction with Java:

Oops, I just located a R-rjava download in the software download…

I go try that out first…

I went to the OpenSUSE R-rjava download page:
https://software.opensuse.org/package/R-rJava?locale=fa
In Yast, it gave me two options
https://download.opensuse.org/repositories/devel:/languages:/R:/released/openSUSE_Leap_15.1/
http://download.opensuse.org/distribution/leap/15.1/repo/oss/
“https://download.opensuse.org/repositories/devel:/languages:/R:/released/openSUSE_Leap_15.1/ ” is the default choice, and I went along with it. “http://download.opensuse.org/distribution/leap/15.1/repo/oss/ ” is left unchecked.
I then use the “R CMD javareconf” in xTerm but it did not work:
linux-3ztp:/home/by79 # R CMD javareconf

“R CMD javareconf” also came up in the R console earlier when I was trying different ways to get it to work. I am guessing that the whole problem has to do with setting the Java environment and path? https://www.ibm.com/support/knowledgecenter/SSPT3X_3.0.0/com.ibm.swg.im.infosphere.biginsights.install.doc/doc/install_install_r.html karlmistelberger, appreciate your suggestion though.
I then went back to the the R-rjava download page. This time I chose both “https://download.opensuse.org/repositories/devel:/languages:/R:/released/openSUSE_Leap_15.1/ ” and “http://download.opensuse.org/distribution/leap/15.1/repo/oss/ ”…for some reason, it looks to be working now.

When you use openjdk instead of Oracle Java, the openjdk package is equivalent to the Oracle JRE and openjdk-devel is roughly (not exactly the same)equivalent to the Oracle JDK.
Since you’re building something in Java and not just running a pre-compiled Java app, you need the JDK with its development headers and additional libraries.
Run the following to discover what “openjdk-devel” packages are available, and install the one that’s appropriate for your currently installed Java. Note that your first post says you were configured to use openjdk 1.8 and the next posts say you were running openjdk 11. If uncertain what you need, install all three openjdk-devel packages, they should install side by side and won’t hurt.
zypper se openjdk-devel
You can install packages by space delimiting as follows
zypper in *pkg1 pkg2 pgk3*
If you have multiple Java installed on your system, you can switch between them with
update-alternatives --config java

Thanks tsu2. great to hear from you as always.
Run the following to discover what “openjdk-devel” packages are available, and install the one that’s appropriate for your currently installed Java. Note that your first post says you were configured to use openjdk 1.8 and the next posts say you were running openjdk 11. If uncertain what you need, install all three openjdk-devel packages, they should install side by side and won’t hurt.
If you have multiple Java installed on your system, you can switch between them with

S | Name | Summary | Type

i | java-11-openjdk-devel | OpenJDK 11 Development Environment | package
| java-1_8_0-openjdk-devel | OpenJDK 8 Development Environment | package
I think I am currently using java-11-openjdk-devel…I was trying various versions installation via YAST earlier to try to get R to work, and stumble upon this version. Maybe the R-rjava download did something to make it work? Thanks again for your insight; helps me to get a better understanding how things work.

Thank you karlmistelberger and noted. I am not well versed with systems and software but want to learn, so sometimes, I am not even asking the right questions, or not implementing things as they should be and there will be some gaps. Hope that you could be patient with me.
