[R] chi square problem

[Daniel Fodor]

   Dear all,

   I  have a problem that I could not solve neither with spss nor with R.
   Please,  excuse  me  if it is atrivial question but I did not find any
   soultion.

   I  have  the followig practical problem: we a product that has A, B, C
   effects  (we  differentiated  about  30) on health and we want to know
   whether  these effects are  associated  with  its  physical properties
   (shape,  size,  color).  We  listed  all  these  30  effects that were
   important  for  us and the subjects received a list of photos in which
   the  product was indicated in different size and color etc. There were
   20 possiblities. The subjects had to order one of these photos to each
   effect in the list.

   If  I  make a chi-square test it says only that there is a significant
   effect. I  also  want to know which property or properties caused this
   significant effect in the deviation from expected frequency.

   I would appreciate your help.

   Daniel

[R] rcmdr help

[Daniel Fodor]

Dear All,

I use Debian etch and downloaded R from its repo. Although it is running I 
would like to make the first steps using rcmdr. I went through on wikis and 
howtos, installed rcmdr but it is not running. Apparently it is properly 
installed, there is an Rcmdr library in /usr/lib/R/site-library but I cannot 
start it neither from command line nor by clicking on applications - debian 
- apps - math - GNU R. Clicking on it starts R without GUI. Tcl 8.4 was 
already installed and there are no broken packages. I would appreciate any 
kind of help in starting R with gui. Please, excuse me if it is a trivial 
question, I am newbie to R.

Best wishes

Daniel
