R help - Mar 2009 - R-help

Hi list,
When I type my question in R console using ? sign (example: ?par, when I
want to query for par), the following error message popps up:

Error in
print.help_files_with_topic("C:/PROGRA~1/R/R-24~1.1/library/maps/chm/map")
:

        CHM file could not be displayed

I appreciate if any body comes back to me with the solution.
Regards,
Alireza

So, it seems you are using Windows.  One possibilty is that your 
Windows security settings are stopping you displaying CHM help files: 
if you have control over these you could try to resolve that.

Another alternative is to change the default type of help used: the 
settings for that are in the file etc/Rprofile.site in the R 
installation.  If you don't have permission to change that, you could 
use e.g.

options(chmhelp=FALSE, htmlhelp=TRUE)

in a .Rprofile file in your home directory.

Finally, R-24~1.1 looks like an old version of R, and you could 
install a current version: the installer will ask if you want custom 
settings and if you select that, ask you for the default type of help.

That does not seem to be the message that goes with the example.

Greetings and best wishes to you!

Dear all,

I am currently doing my M.Sc. thesis on the combined applications of
robust and ridge regression. I have a set of 6 continuous variables
for more than 35, 000 cases. In fact, I know how to handle ridge
regression and robust regression separately using statistical
packages. However, my data show me that the two problems happen at
once, i.e., both multicollinearity and outliers do exist in my data
set so that I could not able to get an estimator, which is based on
robust-ridge regression using R.

The parameter that I want to estimate is given by: (X'WX + kI)-1 X'WY,
where k is the baising constant in ridge regression and W is the
daigonal matrix of weights, which is obtained by itteratively weighted
least squares.

Thank you for your time and considering my letter!
