[R] Error using write.xlsx library(xlsx)

[Quark at gmx.at]

Dear Adrian,

I would like to export a quite large matrix from R to Excel (40 columns, 257 597 rows). After 10 minutes of work, I get the following error message:

Error in .jcall(row[[ir]], "Lorg/apache/poi/ss/usermodel/Cell;", "createCell",  : 
Java Exception <no description because toString() failed>


This is the code I used:

write.xlsx(wvs19812008hm, "C:/test.xlsx", sheetName="Sheet 1", formatTemplate=NULL, col.names=TRUE, row.names=TRUE, append=FALSE)


Is the matrix simply too large? (NB: I use the 64bit version of Windows 7 and R x64 2.12.1)

Thanks,

Tobi
