If you are working on a Windows computer and want to schedule your R scripts while you are off running, sleeping or having a coffee break, the taskscheduleR package might be what you are looking for.

The taskscheduleR R package is available at https://github.com/jwijffels/taskscheduleR and it allows R users to do the following:

i) Get the list of scheduled tasks

ii) Remove a task

iii) Add a task

– A task is basically a script with [R code][R_code] which is run through **Rscript**
– You can **schedule** tasks ‘ONCE’, ‘MONTHLY’, ‘WEEKLY’, ‘DAILY’, ‘HOURLY’, ‘MINUTE’, ‘ONLOGON’, ‘ONIDLE’
– After the script has run, you can check the **log** which can be found at the same folder as the R script. It contains the stdout & stderr of the Rscript.

Below, you can find an example how you can schedule your R script once or daily in the morning.

      library(taskscheduleR)<br>myscript <- system.file(
      “extdata”
      , 
      “helloworld.R”
      , package = 
      “taskscheduleR”
      )<br><br>## run script once within 62 seconds<br>taskscheduler_create(taskname = 
      “myfancyscript”
      , rscript = myscript, <br>  schedule = 
      “ONCE”
      , starttime = format(Sys.time() + 62, 
      “%H:%M”
      ))<br>## run script every day at 09:10<br>taskscheduler_create(taskname = 
      “myfancyscriptdaily”
      , rscript = myscript, <br>  schedule = 
      “DAILY”
      , starttime = 
      “09:10”
      )<br><br>## 
      delete
       the tasks<br>taskscheduler_delete(taskname = 
      “myfancyscript”
      )<br>taskscheduler_delete(taskname = 
      “myfancyscriptdaily”
      )
     

When the task has run, you can look at the log which contains everything from stdout and stderr. The log file is located at the directory where the R script is located.
