Can't load package FSelector for hill.climbing.search
I want to use the hill.climbing.search on my data to detect the most significant deviation in my data.
Therefore, I wanted to install the package FSelector which works, but when loading the package I receive this error message:
> library(FSelector)
Error: package or namespace load failed for ‘FSelector’:
.onLoad in loadNamespace() for 'rJava' failed, Details:
Call: fun(libname, pkgname)
Error: JAVA_HOME cannot be determined from the Registry
In addition, I read the introduction to hill.climbing.search from the pdf from CRAN for FSelector package, but I am confused what in my data the parameters attributes and eval.fun are.
Here is my data:

JAVA_HOME is an environmental variable set by installing JDK. Installing JDK and pointing your JAVA_HOME env variable to the /bin sub-folder of the JDK should resolve that.Sys.setenv(JAVA_HOME='PATH_TO_JDK')
