Packages couldn't load

Emeka Don
Dear All,
I have been trying to install Xlsx package in R but  i have been getting
this error after the installation. Please can anyone help?

> any(grepl("xlsx",installed.packages()))
[1] TRUE
> library("xlsx")
Loading required package: rJava
Error: package or namespace load failed for ‘rJava’:
 .onLoad failed in loadNamespace() for 'rJava', details:
  call: fun(libname, pkgname)
  error: JAVA_HOME cannot be determined from the Registry
Error: package ‘rJava’ could not be loaded
In addition: Warning messages:
1: package ‘xlsx’ was built under R version 3.4.3
2: package ‘rJava’ was built under R version 3.4.3

Thank you

You need to make sure that the rJava package is working.

Consider using the readxl package instead of xlsx.

Re: Packages couldn't load

MacQueen, Don
Or the openxlsx package, which does not require Java, and is similar to the xlsx package in functionality (both reads and writes, for example).
