R help - Jul 2005 - fitting extreme value distribution

hi,
  rgev function gives me random deviates and I have a data
set which I am fitting to an EVD,IS there a way I can plot
both observed and ideal evd on the same plot
thankyou

If this is a question about plotting 2 series on a plot then in general terms
you can plot 2 series as per this example in the list
http://finzi.psych.upenn.edu/R/Rhelp02a/archive/5463.html

If it is about the use of rgev you should tell us the name of the package.

If you read the posting guide you will find ways to help imporve the way that
you ask questions, so that it is easier for people to give you an answer that
works for you.

Which "rgev" are you using?  There are at least two in at least three 
different packages:  evd, evir, and fExtremes.  I found this by using 
'help.search("rgev")', which will however only identify
related material
I already have installed locally.  'RSiteSearch("rgev")'
produced 22
hits, the first of which was for the one in fExtremes.  The 
documentation for the one in fExtremes includes a reasonable plotting 
example.  Regarding fitting, have you considered fitdistr in 
library(MASS)?

	  Beyond this, may I suggest you PLEASE do read the posting guide! 
http://www.R-project.org/posting-guide.html.  It can increase the 
likelihood you will get a useful reply relatively quickly.

Top 10 reasons to become a Statistician

     1. Deviation is considered normal
     2. We feel complete and sufficient
     3. We are 'mean' lovers
     4. Statisticians do it discretely and continuously
     5. We are right 95% of the time
     6. We can legally comment on someone's posterior distribution
     7. We may not be normal, but we are transformable
     8. We never have to say we are certain
     9. We are honestly significantly different
    10. No one wants our jobs
