HOW TO RUN SCRIPT ON MAC MAC
You can make sure your Mac wakes up a minute or two before your job is scheduled to run by going to System Preferences > Energy Saver > Schedule and set the Start Up or Wake time. But if it’s asleep, the script won’t run either. Oh, and one final point: Of course if your Mac is off, the cron job won’t run. Otherwise you can end up spending a lot of time wondering why your script isn’t running, when it IS running, but it’s storing your data someplace you didn’t expect. If your cron job includes saving a file, remember this. On a Mac, that file will be in your home directory, unless you specify another location. RStudio understands that you’re in your project directory. One really important point: The test.txt file that’s created by this cron job will NOT be in my project directory. You can see in the bottom left RStudio panel, details for the new cron job that was created on my system. Then I just need to click on the Create job button at the bottom, and Done.

Pick the time I want, and whether I want it running every hour, every day, and so on. If you click “Schedule R scripts on Linux/Unix” under CRONR, here’s what comes up Mine are all already installed, including the add-in. If they’re already on my system, they just load. Then with p_load, I’m installing a few packages if they’re not already on my system –miniUI, shiny, and shinyFiles. Here I’m installing cronR from the b.n.o.s.a.c. I like using the pacman package for installing and loading packages. If you want its RStudio add-in to work, you need a few other packages, too. Otherwise, you may want to check out the cronR package. If you are familiar with Unix cron jobs, you can schedule them in your Mac terminal. And, there’s a cool R package that works with cron and RStudio add-ins. But I’ve been using cron for a long time, and I think it’s easier than launchd. The new approved way is to use Apple’s launchd. In theory, cron isn’t the preferred way to do this on a Mac. Last step is to set up what’s called a cron job, using something called crontab. 755 lets the file owner read, write, and execute the file (that’s the 7) and everyone else can read and execute it (but not change it those are the 5’s). Typical way is with change mode 755 and the filename. Running the c.h.m.o.d change mode command on the file sets the files permissions. If you’d like to schedule this to run automatically, there are a couple of more things you need to do.įirst, make sure the file is “executable” by your system, not just when you type in the terminal. Now I can run my test.R script with Rscript space test.R: In this Linux-like terminal, the command to change directories is cd, and not R’s set.w.d. Let me change directories so my terminal is in my More With R directory. You can find out exactly where that is by running which Rscript in your Mac terminal: Let me run thisĪnd you can see what my current time is in the Environment tab, and when the test.txt file was modified Here, I’m saving it to a file called test.txt.

OK, 4th line uses the base R cat() function, which displays or saves contents of a variable. Any code or variable name inside curly braces within a quoted character string gets evaluated, and the value is used in the string. Third line creates a message variable with the character string “This is a test I’m running at” and the current time variable.īy the way, if you’ve never used the glue package before, it can be a nice alternative to using paste. Here, I’ve got a test script that saves the system time in a variable called current_time. Let me walk you through one way to do this. For smaller things where you can live with the occasional fail, you can set up a Mac to run scripts from the command line. But sometimes once you finish your script, you’d like it to run every week or every day, without having to kick it off manually.įor important, mission-critical work, there are scheduling solutions like RStudio Connect. RStudio is a handy interface to work interactively. I’m here with Episode 11 of Do More With R: Schedule R scripts to run from the Mac command line.
