R help - Apr 2007 - help interpreting the output of functions - any sources of information

Hi,

I am looking for documentation, reference guides, etc. that explain the
output of functions... For example using cor.test(....,
method="pearson")
with Pearson's corr coeff the output is:


    Pearson's product-moment correlation

data:  a and b
t = 0.2878, df = 14, p-value = 0.7777
alternative hypothesis: true correlation is not equal to 0
95 percent confidence interval:
 -0.4355690  0.5514366
sample estimates:
       cor
0.07669612


What are all these? Apologies but I am new in R and statistics in
general.... but a textbook I was looking at, regarding SPSS, explains only
the r coeff and the conf interval.... Any help with sources I can refer to?
Particularly in a broader context as it would not be nice to post all the
time such questions...

Thanks in advance,
GM

Hi,

If you look at the documentation for the function you are interested
in, in this case ?cor.test, it will generally give you an explanation
of the return values (often brief, and not too helpful if you aren't
already familiar with the test), but also one or more references
that you can turn to for further information.

Most likely, though, you'll want to absorb a general
introductory stats book before you delve into the
gory details of many of those references.
