I have a problem with the write.xlsx2
function of xlsx
R package. For instance, see the code below.
main_path<-"~/mydir/"
read.xlsx2(paste0(main_path,"my_input_excel.xlsx"), sheetIndex=1)
a<-1
write.xlsx2(a, paste0(main_path,"my_output_excel.xlsx"), sheetName="Sheet1", col.names=TRUE, row.names=FALSE, append=FALSE)
While read.xlsx2
function works fine, write.xlsx2
function gives the error
Error in
.jnew("java/io/FileOutputStream", jFile)
:
java.io.FileNotFoundException: /mydir/my_output_excel.xlsx (No such file or directory)
When I remove the paste0
part and write only the file name everything is fine again. So the problem is to define path.
p.s I am wondering, perhaps the write.xlsx
ignores the tilde ~
so path definition becomes garbage.
Replacing "~/" with "Users//" works for Mac (probably for Linux as well). Though, it still eludes me how read.xlsx
and write.xlsx
could differ in such a fundamental way.
