R help - Sep 2004 - new user and non parametric test

Hi *

i'm trying to do my statistical analysis with R (on a debianGNULinux)
i've installed R and now i'll try to import my data from .xls 

Where to search for non parametric test in R ? 
I'm studing neurons velocity and i've to check if after the perfusion
with a factor x the velocity changes but as my variable is not normally
ditributed i've to try with non parametric test (i think)

thanks
paolo

?wilcox.test
?friedman.test

etc. - it's true. I didn't find an easy way to find certain test in R
either. But e.g.

  apropos("wilcox")

will help.

Furthermore I recommend the book

@Book{siegel88,
  Author         = {Siegel, S. and Castellan, N. J.},
  Title          = {Nonparametric Statistics for the Behavioral Sciences},
  Publisher      = {McGraw-Hill, Inc.},
  Address        = {Singapore},
  year           = 1988,
}

Regards,
  Christoph.
