OutOfMemoryError (Java) : Java heap space

Question

I'm trying to add 10 more rows at the end of an excel table (currently 27k rows long)

options(java.parameters = "-Xmx4g" ) ; 
library(XLConnect) ;
writeWorksheetToFile("H:/R/myfile.xlsx",DataTable,sheet="Sheet1",startRow=row1,startCol=1,header=FALSE,rownames=FALSE) 

after some seconds I receive the error

OutOfMemoryError (Java) : Java heap space

How can I fix this? Shouldn't options(java.parameters = "-Xmx4g" ) work?

Answer 1

Try using openxlsx package. I had problems with XLConnect and Java.
