R help - Sep 2012 - p-values in agricolae pearson correlation

I have used the correlation analysis (pearson) in the agricolae package to
analyse my data and got unexpectedly low p-values (therefore making many
more highly significant correlations in my data than I had expected). I am
wondering if the p-values given should be subtracted from 1 to give the real
p-value, because for each variable compared against itself has a p-value of
1 and I thought it should be zero. I'm really not very confident about this
and I'd really appreciate it if anyone who uses correlation analysis in
agricolae could tell me if the p-values generated can be used as they are.

I have never used the package but a quick look at the manual suggests a number
of corrections for multiple correlatins so you probably should look into it. 
See "kruskal" in the manual for a start.
