SCoR - An R package for Microbiome Correlation

Installation

library(devtools)
devtools:install_github("AbhishakeL/SCoR")

Pre-requisites

Install FastSpar.

Pipeline

1. Create a phyloseq object. Possible examples can be found here or here .
2. Use FSprep() to create metadata attribute-wise partitioned OTU table.
3. Write the output of the previous command to a file.
4. Run FastSpar on the previous file.

5. Remove the # from the first cell in the correlation table and p-value table output from FastSpar.

6. Use scor() to generate the final output. Please follow example for details of parameter.
7. Visualise network using igraph or Cytoscape.
