R code and data sets.

“Abundscale.Rdata” is the original species relative abundance data. “Parascale.Rdata” is the original environmental parameters data. Due to the long computation time on the original data, two shorten data sets “Abundscale_short.RData” and “Parascale_short.RData” are also provided for the fast test. “test_git.R” is the code for the analysis workflow on both of original data and the shorten data. “InteractionAnalysis_git.R” contains all the developed functions which are used in “test_git.R”.
