Cant schedule R script with cron

This is my crontabenter image description here

It´s supposed that my script on R saves csv on my directory.

write.csv(raw_data, paste0("/Users/marianafernandez/Desktop/prueba/data-raw/database_pulls/raw_data/raw_data_", Sys.Date(), ".csv"), na = "", row.names = F)

If I run on my terminal: R Script scraping.R everything goes fine. But when I try to do my cronjob is not working, nothing happens. Help me please

cron is still supported by OSX but it has been deprecated in launchd.

You need to create a "plist" file and place it in folder ~/Library/LaunchAgents. Example plist file:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
  <dict>
    <key>Label</key>
    <string>example</string>
    <key>ProgramArguments</key>
    <array>
      <string>Rscript /path/to/example.R</string>
    </array>
    <key>StartCalendarInterval</key>
    <dict>
      <key>Minute</key>
      <integer>0</integer>
      <key>Hour</key>
      <integer>23</integer>
    </dict>
  </dict>
</plist>

You need to load this plist file into the launchd scheduler and start it:

 launchctl load ~/Library/LaunchAgents/example.plist
 launchctl start example

Name example corresponds to the field Label in the plist file.

More likely than not you need to put the path TOO the Rscript in front of it path/to/Rscript and it will correct the problem...that worked for me.
