Problems to install.package(rJava) in MacOs High Sierra 10.13.6

[evodio]

Work on MacOS High Sierra 10.13.6.
When I try to load the packages (xlsx and rJava) I get the following errors:

library(xlsx)
Error: package or namespace load failed for ‘xlsx’:
.onLoad failed in loadNamespace() for 'rJava', details:
call: dyn.load(file, DLLpath = DLLpath, ...)
error: unable to load shared object '/Library/Frameworks/R.framework/Versions/3.5/Resources/library/rJava/libs/rJava.so':

I have tried the following options and nothing has worked for me:

• sudo ln -f -s $(/usr/libexec/java_home)/jre/lib/server/libjvm.dylib /usr/local/lib

• Install the latest version of Java

• R CMD javareconf

ANYONE WITH A SOLUTION?
THANKS.

This isn’t a direct answer (sorry!), but getting the Java system requirement for xlsx working properly is notoriously a pain, so it seemed worth mentioning that there are now a few other packages that cover the same ground without requiring Java. There’s a good list at the end of the README for readxl (one of these Java-free packages):

Read Excel Files

/Library/Java/JavaVirtualMachines/jdk-9.jdk/

Can you post the output of

R CMD javareconf

and

/usr/libexec/java_home

?

Thanks, I found the solution after days of looking at the following site:

Run rJava with RStudio under OSX 10.10, 10.11 (El Capitan) or 10.12 (Sierra)

If your question's been answered (even by you!), would you mind choosing a solution? It helps other people see which questions still need help, or find solutions if they have similar problems. Here’s how to do it:

FAQ: How do I mark a solution?

If your question has been answered, don't forget to mark the solution! How do I mark a solution? Find the reply you want to mark as the solution and look for the row of small gray icons at the bottom of that reply. Click the one that looks like a box with a checkmark in it: [image] Hovering over the mark solution button shows the label, "Select if this reply solves the problem". If you don't see the mark solution button, try clicking the three dots button ( ••• ) to expand the full set of options. When a solution is chosen, the icon turns green and the hover label changes to: "Unselect if this reply no longer solves the problem". Success! [solution_reply_author] …

It also works for me, just open the terminal to set:

LD_LIBRARY_PATH=`/usr/libexec/java_home`/jre/lib/server open -a rstudio
LD_LIBRARY_PATH=`/usr/libexec/java_home`/jre/lib/server open -a R
