[R] question from environmental statistics

[pantd@unlv.nevada.edu]

thanks Fran. that was useful but Im still in a fix. its a real life data which
looks like this:
0.9
10.9
24.0
6.7
0.6
1.0
2.4
12.4
7.9
15.8
1.4
7.9
11000.0

(benzene conc. taken after WTC attacks)..its just a small chunk of data i pasted
for you to look at.
its neither normal nor lognormal. someone told me that qq plot does help in
determining the distribution. im not sure how to get it.

can someone help me in this.

thanks



Take a look at this document by Vito Ricci:
http://cran.r-project.org/doc/contrib/Ricci-distributions-en.pdf

Did you try RSiteSearch("Fit distribution") or a Google search?  That will
lead you to fit.dist{gnlm} and fitdistr{MASS}

Cheers

Francisco
