[R] output

[Val]

Hi all,

I have a data frame with more than 100,000 rows.

datx <- function(n,mean,sd) { mean+sd*scale(rnorm(n)) }
dat <- datx(110000,10,2)

1)
WriteXLS(dat, "test4.xls", row.names=FALSE)
Error in WriteXLS(dat, "test4.xls", row.names = FALSE) :
  One or more of the data frames named in 'x' exceeds 65,535 rows or 256 columns

I noticed that *.xls has  row and column limitations.

How can I take the excess row to the next sheet?

2) I also tried to use xlsx and have a problem

write.xlsx(dat, "test3.xlsx",sheetName="sheet1", row.names=FALSE)
Error in .jnew("org/apache/poi/xssf/usermodel/XSSFWorkbook") :
  java.lang.OutOfMemoryError: Java heap
space.jnew("org/apache/poi/xssf/usermodel/XSSFWorkbook")<S4 object of
class "jobjRef">

Any help ?
Thank you in advance
