I am getting the following error while trying to load xlsx package.

library(xlsx) Error: package or namespace load failed for ‘xlsx’: .onLoad failed in loadNamespace() for 'rJava', details: call: fun(libname, pkgname) error: JAVA_HOME cannot be determined from the Registry

Can any one please help me with this. I am stuck in this since last two days.

After I installed the package it was installed in user library. I pasted the same at the R library location so that it might take the package from that location but it dint worked.

library(xlsx) Error: package or namespace load failed for ‘xlsx’: .onLoad failed in loadNamespace() for 'rJava', details: call: fun(libname, pkgname) error: JAVA_HOME cannot be determined from the Registry

  • There appear to be several open issues with this package related to Java. See https://github.com/colearendt/xlsx/issues – markhogue Jun 09 '19 at 03:51

    "Open issues", perhaps, but none of them include `JAVA_HOME`; there are three closed issues that do, but none of them seem to be about this error. @markhogue, are you certain that this issue is a known-thing with `xlsx`? If so, please link to is specifically. – r2evans Jun 09 '19 at 04:07
  • Other than that, if you search (google or other engines) for `R xlsx rJava JAVA_HOME`, you'll find many references off of StackOverflow. Within SO, if you search for `[r] rjava java_home`, you will find many answered questions about this issue, and they all revolve around mis-installation of java and/or inability to find the system-installed java. – r2evans Jun 09 '19 at 04:09

    @r2evans I had nothing specific. Deferring to your better comment. – markhogue Jun 09 '19 at 17:47
