The error seems to have cropped up after I uninstalled some old version of Java.Īlso just to add, I do not set JAVA_HOME as a environment variable. #Unable to load xlsx rjava in r windows 7 If you're just trying to write XLSX files, I recommend using the package openxlsx since it does not have the Java requirement. Uninstalling and Reinstalling R also doesn't seem to fix the problem. You can always read XLSX with readr also. After installing the package we can load the package as a library into the R environment and later use it to load excel data in R. Removing older java versions is too of no help.
#Unable to load xlsx rjava in r windows 7.#Unable to load xlsx rjava in r install.Within that function there is a subfunction called find.java. The function that rJava uses to find Java is in the rJava.onLoad function. If that doesn't work, you can start looking at exactly where R is looking for your Registry entries. This should put the entries back in your Registry. If you installed Java, try reinstalling it. You can install either the Java Runtime Environment or the Java Development Kit. Either your registry is corrupt, but more likely you haven't installed Java. The error is telling you that there is no entry in your Registry that tells R where Java is located on your machine.
