devtools::install_github("MikkoVihtakari/sclero")

Contributions and contact information

Any contributions to the package are more than welcome. Please contact the package creator Mikko Vihtakari (mikko.vihtakari@gmail.com) to discuss your ideas on improving the package.

Dependencies

The sclero package depends on:

• RImageJROI package. Used to import ImageJ ROI objects to R.
• spatstat package. Used for geometric calculations.
• plyr package. Used for quicker and easier list calculations. This dependency could potentially be removed, but the removal would require rewriting many functions included in the sclero package

News

2019-06-03 Update to a new major version, which is still developmental. Added growth measurement and edited most underlying functions. Might have broken something. For test use only.
