#Introduction This is the repository for an R package that provides code to aggregate responses to the Power Curve Working Group "PCWG_Share_01" exercise. More details of the exercise can be found at http://www.pcwg.org and http://www.pcwg.org/PCWG-Share-01/PCWG-Share-01-Definition-Document.pdf.

#Requirements

1. A working installation of R. This can be obtained from e.g. http://r-project.org.
2. A GUI for R. R-studio is strongly recommended. See http://rstudio.com.
3. Two or more data files from the Power Curve Working Group Tool, prepared for PCWG_Share_01

How To Use This Code

1. Create a directory somewhere and place the contents of the zip file into that directory (let's call this $root). It is recommended that there be nothing else in the directory.
2. Load the PWCG tool data files into a 'data' directory in $root. You can add directories for different sites, etc.
3. Open PCWG_share_01_main.rmd in Rstudio.
4. Modify project.root to be $root.
5. Decide if you intend the results to be public. If you do, set data.public to TRUE. This will prevent any details of the individual data sets being shown. If data.public is FALSE, all results will be printed.
6. Decide if you want to reanalyze raw data and set data.analyze.raw. This should be TRUE the first time you run the code. Afterwards you can set this to FALSE to just generate plots.
7. Run PCWG_share_01_main.rmd in Rstudio. Either:
8. hit chunks -> run all to run all of the R code and not generate any output PDF or HTML files.
9. hit knit HTML to generate the html results file; this will create an HTML file but will not generate any data in memory
10. hit knit PDF to generate the html results file; this will create an HTML file but will not generate any data in memory

#Documentation Documentation is provided in several forms:

• within PCWG_share_01_main.rmd
• within PCWG_share_01_main.pdf, which will also contain the results when run using knitr.
• within PCWG_share_01_main.html, which will also contain the results when run using knitr.
