Dear devel-listers,
I found a conflct between rJava and data.table. Actually me questions is where
to report it?
Should I rather send it directly to the package maintainers or post it on some
bug tracker.
The problem is that data.table has a function called "J" and rJava uses the
same quite intensively.
I used the xlsx R package which depends on rJava to write .xls files and ran
into an error.
write.xls from this package uses the functions and returns an error depending
on the sequence the packages
were loaded.
Error in .jnew("org/apache/poi/xssf/usermodel/XSSFWorkbook") :
java.lang.AbstractMethodError:
java.lang.ClassLoader.loadClass(Ljava/lang/String;)Ljava/lang/Class;
data.table::J
rJava::J
I can work around this by loading and unloading packages, but I feel this
should be addressed because
loading these two packages that both deal with tables of data does not seem
that unlikely to me.
best
matt
