Hi there,

The package you want to install needs an installation of java. So you need to be sure you have Java installed and it is able to find/is pointed towards that installation.

It is discussed here in detail: java - rJava install error "JAVA_HOME cannot be determined from the Registry" - Stack Overflow

Let me know if this helps

If you want an easier time to work with xlsx files in R I would suggest looking at readxl. See here: https://readxl.tidyverse.org/

Just reinstalled the lastest Java progam and those errors are gone....

Many thanks for your advice, folks@GreyMerchant
