  "Description": "The MAR1 package provides basic tools for preparing\necological community time-series data for MAR modeling,\nbuilding MAR-1 models via model selection and bootstrapping,\nand visualizing and exporting model results. It is intended to\nmake MAR analysis sensu Ives et al. (2003) Analysis of\ncommunity stability and ecological interactions from\ntime-series data) a more accessible tool for anyone studying\ncommunity dynamics.  The user need not necessarily be familiar\nwith time-series modeling or command-based statistics programs\nsuch as R.",
