Abstract
This R script performs statistical analyses using sequence data. It goes through all the steps from reading the data into R, merging multiple datasets, calculating diversity metrics, performing statistical analysis such as linear regression and non-metric multidimensional scaling (NMDS), making graphs and saving and exporting them for use in presentations and publications. It illustrates the analyses used in Gomez-Montano et al. 2013, and can be used as a template for other similar analyses. Sections:
- Preparing data
- Diversity metrics
- Analysis of individual OTU frequencies
- Soil physical and chemical analyses
- NMDS community analysis
