Besides,I would like to plot the relative abundance of each OTU, against the number of significant pair-wise correlations to other OTUs. However, I do not know how to introduce p <.05 parameter in the script.

Please read the posting guide that suggests to submit reproducible code.
We can hardly help "how to introduce p <.05 parameter in the script" if 
we do not know that script.
