coolbear: Obtain T50 values

In pgomba/thermgRad: Tools to Visualize and Analyze Germination in Temperature Gradient Plates

Obtain T50 values

Description

Obtain T50 values using Coolbear et al. (1984) formula modified by Farooq et al.(2005). Vector containing scoring days must have same length than vector containing cumulative germination data

Usage

coolbear(
  day = "vector containing scoring dates",
  cumulative = "vector containing cumulative germination for each day",
  n = "total number of viable seeds"
)

Arguments

day	A vector containing scoring days
cumulative	A vector containing the cumulative germination for each day
n	Number of viable seeds in the Petri dish (Total sown seeds - empty seeds)

Value

t50 value in days

Examples

coolbear(seq(1,10,1),c(0,0,0,0,0,6,12,15,18,20),20)
