I've started to use Rapache although Rserve would also be an option.
When installed on server, your can point your html form to an rhtml
page and get the form variables in R just as with other web languages.
For writing html output, I had been using R2HTML ( see code excerpt below
from rhtml page). I had also found Cairo works ok if you don't
need X-11 for anything. 

For your specific situation however, it may be easier to just
use whatever you already have and just use R for the data analysis.
When a request for a results report is made,  send that to Rapache for
example. I would mention that I have gone to running two versions
of Apache, one with R and one with PHP, to allow for security and
easier development( I can write the php to fail nicely if the R apache
server is not up and no new security issues are exposed). 


library("Cairo")
library("R2HTML")
library("RColorBrewer")


You can of course also generate html from normal R commands, or for that
matter bash scripts etc.

How can we create HTML forms in R????

Hai everyone,

 1) Is there a way to populate html form element values directly into R or
is it only possible to get the values into a db or an excel file or a csv
file and import it for data analysis.

    If possible , please anyone reply to this mail. Am a beginner in R.

I will explain more clearly....

I have an online feedback form which has all the form elements like
radiobuttons,checkboxes,textareas,textboxes etc. I have to get the values of
these form elements and use it for data analysis in R. It will be huge
amount of data.

1) Is it possible in R to retrieve the values of these form elements
directly.

2) Is there any storage mechanism in R to store the values.
2) Do i have to store the data in some files or db and then import them in
R and use for data analysis. Is this better?????

Hi all

So we can retrieve data from mysql database and do the data analysis in R.

Is it easy to do the data analysis with the values of the form elements
stored in mysql db,which are of different patterns for eg:- for radio
buttons there may be values yes or no,some may have textarea
values.....Suppose i want to do a correlation analysis between these two how
is it possible????
Can anyone give an example,Please.
Thanks

 Amrita
