PTBoxProxydata - The data manager for paleo data time series

This package provides the ProxyDataManager class and imposes conventions on format and processing of datasets used within the PaleoToolBox (PTBox) for a more consistent, efficient, and reusable paleodata workflow.

Introduction

The package can be installed using devtools in R:

require(devtools)

devtools::install_git("https://github.com/paleovar/PTBoxProxydata", build_vignettes = TRUE)

library(PTBoxProxydata)

If you'd like to contribute to the package, you might want to clone it (type git clone https://github.com/paleovar/PTBoxProxydata.git in the terminal) and open the .Rproj in RStudio. Please don't hesitate to report issues, bugs, etc. to the authors.

Introduction

After the installation run

vignette('PTBoxProxydata_howto')

for the introductory tutorial and check out the help pages with

?PTBoxProxydata

You can browse the vignette without installing the package as well. Therefore, simply download doc/PTBoxProxydata-howto.html from this repo and open the file in your browser.
