Hi,
I have to upload data from more than 200 separated excel pages and I am using
the read.xlsx function in the xlsx package. Each sheet is an articulated page
(made of more than one table plus extra data) and I need to load into a R data
frame the different elements I find in each page. This procedure needs to be
repeated several times - i.e. on more than one excel file.
Initially I did not have problems and the script run just fine providing the
desired data frame. After running a few hundreds sheets now I get this error
after I upload each page:
Errore in .jcall("RJavaTools", "Ljava/lang/Object;", "invokeMethod", cl, :
java.lang.OutOfMemoryError: Java heap space
Has this to do with some sort of cache that is being filled up? Can anyone
suggest a solution to this error?
Thanks,
Luca
