R package: xlsx

read.xlsx

Unfortunately, there seems to be no stringsAsFactor parameter.

When I tried to execute library(xlsx), my RGui session crashed.

This was apparently caused by a wrong version of the JDK. I had to fix the JAVA_HOME environment variable to get it running:

Sys.setenv('JAVA_HOME' = "C:\\Program Files\\sqldeveloper\\jdk\\jre")
