Hello lima,

Welcome to the forum! It is looking for an installation of java which it cannot find.

Best way to address this:

  1. Install Java
  2. Re-install rJava
  3. Try again to install xlsx. If it doesn't work you need to just change the directory so it is able to find the Java location.

(In the event of it not finding the location it will look something like this to set the directory:

Sys.setenv(JAVA_HOME="C:\\Program Files\\Java\\jre7") # for 64-bit version 
Sys.setenv(JAVA_HOME="C:\\Program Files (x86)\\Java\\jre7") # for 32-bit version

Should I install Java in PC?

you would need Java for R applications to access the Java runtime and work.

alternatively you could use an R package for reading excel that is not based on a java implementation.

I recommend readxl for reading excel into R
