Crontab doesn't execute R script

I'm trying to setup a Cron job on my system by adding the following line 

17 12 * * * Rscript ~/path/to/file/script.R > ~/output_`date +\%d\%m\%y`.txt 2>&1

yet, I cannot see the file the output is being written to. I've consulted the following answers, but to no avail:

Why did my crontab not trigger

CronJob not running

When I run the following command on the terminal:

Rscript ~/path/to/file/script.R > ~/output_`date +\%d\%m\%y`.txt 2>&1

I get the output file as expected. I also added the following line to crontab: 

* * * * * echo hi > ~/output.txt 2>&1

and it works just fine. I'm not sure what is wrong with the first command. Any help would be appreciated. Thanks.

I fixed this by replacing Rscript in my crontab with /usr/local/bin/Rscript (or wherever your Rscript is located - do which Rscript to find out).

Try Below trick, Create one script script.sh like below - 

cat script.sh
Rscript ~/path/to/file/script.R > ~/output_$(date +\%d\%m\%y).txt 2>&1

And then create below entry in crontab. 

17 12 * * * /bin/bash /path/to/script.sh
