Now gracefully fails by returning empty output due to convergence errors or when fitting is not possible.FourPHFfit.bulk - Added better convergence error handling. Added grid search for finding starting values.plot.FourPHFfit.bulk - Now uses geom_errorbar for showing uniformity. Added better plotting without overlap using geom_line2.t50 - Fixes bug causing incorrect results when multiple values of Ni and Nj are present (Thanks to Aude Maugarny @amaugarn).GermValue & GermSpeed - Updated calculations to ignroe NaN values.EmergenceRateIndex - Fix error due to missing total.seeds argument.

testthat.

inst/CITATION.
germinationmetrics 0.1.7 (2022-08-28)
UPDATED FUNCTIONS:
FourPHFfit.bulk - Fixed false "total number of seeds tested is less than the total number of germinated seeds" warning when germination count data is cumulative (Thanks to D. Vijay for Dunna.Vijay[at]icar.gov.in).FourPHFfit - Updated computation of starting values.

GermSpeedCorrected - Use germination percentage instead of counts.EmergenceRateIndex, GermIndex, GermSpeedCorrected, GermValue, GermRateRecip and TimsonsIndex - Minor documentation update.
VIGNETTE:
- Fixed fetching CRAN page for version history to fail gracefully when access is down.
- Updated units in Table 3.
germinationmetrics 0.1.5 (2021-02-17)
NEW FUNCTIONS:
plot.FourPHFfit.bulk - Wrapper function around FourPHFfit for multiple samples.
UPDATED FUNCTIONS:
FourPHFfit - Added warning for low germination percentages. Modified to return NA output for zero total germination inputs with non-converging fits so as not to break FourPHFfit.bulk.

Goldberg (1971), Bilbro and Wanjura (1982), and Fakorede and Ayoola (1980).
UPDATED FUNCTIONS:
FourPHFfit - Added more checks for the input arguments umax, umin, xp, tries and tmax.MeanGermPercent, MeanGermNumber, GermSynchrony, GermUncertainty, TimsonsIndex, GermRateGeorge, GermSpeed, GermSpeedAccumulated, FirstGermTime, GermValue, PeakValue, WeightGermPercent, t50, MeanGermRate, MeanGermTime, germination.indices, FourPHFfit and FourPHFfit.bulk - Fixed the check for uniformity of intervals to handle non-integer values correctly. Closes issue #3.(Thanks to Jonas Ohlsson [@jonasoh])TimsonsIndex and GermRateGeorge- Fixed to handle interval data other than days.
