Welcome to plantTracker! This package was designed to transform long-term quadrat maps that show plant occurrence and size into demographic data that can be used to answer questions about population and community ecology. The overall workflow of this package was inspired by tracking algoritms written by Peter Adler and Bill Lauenroth in 2008, although the code included this package is new. You can read more about the original tracking algorithms in this paper:

Lauenroth, W and P. Adler. Demography of perennial grassland plants: Survival, life expectancy and life span. 2008. Journal of Ecology 96(5): 1023-1032. DOI = 10.1111/j.1365-2745.2008.01415.x
