R help - Mar 2017 - write.xlsx

Hey.

I am trying to append a sheet to an existing file using write.xlsx, see
code under:

write.xlsx(x = data1,file = filename,sheetName = "data1", asTable =
FALSE,
col.names = T,row.names = F,append = F)
write.xlsx(x = data2,file = filename,sheetName = "data2", asTable =
FALSE,
col.names = T,row.names = F,append = T)

However, when using the last line does it not append it to the file, but
overwrite the file. Meaning that the file, which I have have called:

filename <- "test.xlsx"

only includes one sheet - data2. The first data sheet is not there. Why
does not append work with write.xlsx?

Dear Paul

Have you defined a variable T or F somewhere?
Rather than look to find out why not replace T by TRUE and F by FALSE 
and see if that solves your problem.

Also, this is from a package. Which? (AFAIR, there are at least two
possibilities). What is is the docs? Does it even allow an append= argument?
