Hi Marc and all,
Last time you suggest me to use WriteXLS function to write more than
65,000 row in excel. Creating the file worked fine. Now I wanted to
read it using the WriteXLS function but have a problem,. The file
has more than one sheets. Here is the script and the error message.
datx <- function(n,mean,sd) { mean+sd*scale(rnorm(n)) }
dat <-data.frame(datx(110000,10,2))
WriteXLS(dat, "test5.xlsx", row.names=FALSE)
I created several sheets by copying the first sheet
t1<- read.xls("Test6.xlsx",2, stringsAsFactors=FALSE)
I am getting an error message of
Error in read.table(file = file, header = header, sep = sep, quote = quote, :
no lines available in input
Thank you in advance

Marc, Thank you so much! That was helpful comment. On Mon, Dec 12, 2016 at 10:09 PM, Marc Schwartz <marc_schwartz at me.com> wrote:
Hi, With the WriteXLS() function, from the package of the same name, if you specify '.xlsx' for the file name extension, the function will create an Excel 2007 compatible file, which can handle worksheets of up to 1,048,576 rows by 16,384 columns. Thus: WriteXLS(dat, "test4.xlsx", row.names = FALSE) That is all described in the help file for the function. Regards, Marc Schwartz

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
