在R中使用xlsx包

Question

I am trying to export a data table from R into excel. I installed the xlsx package and it gave me the following output:

Installing package into ‘C:/Users/Jack/Documents/R/win-library/3.4’
(as ‘lib’ is unspecified)
--- Please select a CRAN mirror for use in this session ---
trying URL 
'https://mirrors.sorengard.com/cran/bin/windows/contrib/3.4/xlsx_0.5.7.zip'
Content type 'application/zip' length 401236 bytes (391 KB)
downloaded 391 KB

package ‘xlsx’ successfully unpacked and MD5 sums checked

The downloaded binary packages are in
    C:\Users\Jack\AppData\Local\Temp\Rtmp04FZrB\downloaded_packages

Then when I went to load with library("xlsx") , It said:

Loading required package: rJava
Loading required package: xlsxjars

Then I tried to do the line:

write.xlsx(x,file="myfile.xlsx",sheetName="Sheet1",append=False)

but it never let me enter the command, it kept pushing me onto a new line.

Can somebody give me some guidance on what is wrong?

Answer 1

Just tried running this on my R console.
It's because in R, logical FALSE should be capitalized or just called as F .
With write.xlsx(x, file = "myfile.xlsx", sheetName = "Sheet1", append = False) , it thinks False is a predefined variable.
Try write.xlsx(x, file = "myfile.xlsx", sheetName = "Sheet1", append = FALSE) . It works for me.
