The Dendrochronology Program Library in R (dplR)

cwt

 

 

 

dplR is a software package in the R statistical programming environment for tree-ring analyses. R is the world's preeminent open-source statistical computing environment where users can contribute packages, which are freely available on the internet. dplR can read standard decadal-format files and perform several standard analyses.

These include interactive detrending, chronology building, and calculates standard descriptive statistics. The package can also produce a variety of publication quality plots. Most importantly, the dplR package will make it easier for dendrochronologists to take advantage of the awesome power of R and use it as their primary analytic environment.

Here is the link to the library on the Comprehensive R Archive Network where you can download source or precompiled binaries. Within R, dplR can be installed, loaded, and the help pages can be seen via:
