# R scripts for fitting composite curves of charcoal data #

The intention of these pages is to describe and document the analysis steps that were developed as a set of Fortran programs, and are now implemented in the R `paleofire` package, with a focus on GCDv3 (Marlon et al., 2016).  The scripts also provide a "point-of-departure" for the development and testing of additional analysis procedures that are not currently implemented in the `paleofire` package.

Contents:

- <font face="sans-serif">Overview:</font>  Discussion of analysis steps
- <font face="sans-serif">Analyses:</font> Annotated (RMarkdown) code for the analyses
- <font face="sans-serif">Code:</font>  R code that can be saved and run as scripts
