r - Create zip file: error running command " " had status 127

Question

I am trying to create a zip file from multiple files using the zip function in r, but I keep getting this error message: running command '"zip" -r9X "data.zip" "dt1.txt" "dt2.txt" ' had status 127.

How can I avoid that?

setwd()
dt1 <- sample(1:100, 10)
dt2 <- sample(100:200, 10)
write(dt1, "dt1.txt")
write(dt2, "dt2.txt")

zip('data.zip', files =c('dt1.txt', 
                         'dt2.txt'))

Answer 1

Here is how I solved this problem on my Windows 7 computer:

1. Install Rtools from HERE.
2. Locate the folder that Rtools is installed. In my case it is at C:Rtools.
3. Add C:Rtoolsin path to the system path.

Adding C:Rtoolsin to the system path:

1. Go to Control Panel >> System and Security >> System
2. Go to Advanced System Settings
3. Open Advanced tab
4. Click Environmental Variables... button
5. Select Path variable and click Edit button
6. If there is nothing as a "Variable Value" you can simply write C:Rtoolsin. If there is already a value, then add ;C:Rtoolsin to the end of it.
7. Click OK, OK...
8. Restart R, it should work.

I hope this helps. I found the solution HERE.
