Executing R script from PHP does not work
I tried to execute this simple R script from PHP as follows. I put both of these files in / var / www / html and changed their permissions to 777.
R Script
col1 = c(1,2,3,4,5) col2 = c(2,2,2,2,2); df = data.frame(col1,col2); write.csv(df,'/var/www/html/outputfromR.txt',row.names=FALSE)
PHP Code
<?php
exec("sudo Rscript test.R");
?>
However, no outputfromR.txt file is generated. Is it a permission issue? How do I resolve it?
