I am trying to connect my R script with my PHP/HTML code. I'm quite well-versed in R but a novice in PHP. My R code requires the use of packages that the PHP command will not load.
Here is the R script:
print(Sys.time())
library(tinytest, lib.loc = c(".../R/R-4.2.1/library","...www\\mypage"))
print("worked")
And here is the sample PHP script:
<?php
echo "Testing";
echo shell_exec ("Rscript /.../www/mypage/my_script.R");
?>
What ends up being printed is as follows:
Testing [1] "xxxx-xx-xx xx:xx:xx EDT"
The PHP and R scripts are saved in the same www location. R is installed on the computer.
I've tried a variety of solutions on both R and PHP:
For R:
For PHP:
I have tried many solutions but these are the ones I suspect:
I'm not sure what else I can do. I could try and look into Apache and RServe, but some permissions issues make it difficult. I've looked into a lot of stackoverflow questions around this topic, but still am unable to solve it. Any ideas?
I am running R version 4.2.1, Windows 10, and PHP version 5.4.16.
