I designed a web page that lets user define some criteria using drop-boxes etc. and php collects the relevant data from the database according to that criteria.
What I intend to do is modeling a least squares trend line over that data using R and displaying coefficients and plot etc.
But I'm unable to run R, though it's installed in the server and works as expected when invoked within the server. I guess there are some security issues.
Can anyone lead me to a solution. My hosting company says it's impossible to run a exec() command to invoke R within PHP because of security reasons.
Thanks so much, jan
