Seed Germination Indices and Curve Fitting
Overview
Provides functions to compute various germination indices such as germinability, median germination time, mean germination time, mean germination rate, speed of germination, Timson's index, germination value, coefficient of uniformity of germination, uncertainty of germination process, synchrony of germination etc. from germination count data. Includes functions for fitting cumulative seed germination curves using four-parameter hill function and computation of associated parameters. See the vignette for more, including full list of citations for the methods implemented.
OTHER NOTES:
- Added internet service checks using
curlin vignettes. - Updated to use
curlinstead ofRCurlfor url existence checks. - Fixed
vnuerrors.
