Analysis: Logistic regression by treatment over time

Description

Performs the construction of a logistic regression graph by treatment over time

Usage

curve(
  dados,
  trat,
  nrep,
  time,
  n,
  model = LL.3(),
  ylab = "Emergence (%)",
  xlab = "Time (days)",
  legend.position = c(0.2, 0.8)
)

Arguments

dados	data.frame containing the responses of the evaluations in separate columns side by side and without the columns with the identification of the factors
trat	vector of treatments with n repetitions
nrep	Number of repetitions
time	vector containing time
n	total seeds per repetition
model	logistic model according to drc package
ylab	y-axis name
xlab	x-axis name
legend.position	Legend position

Value

Returns a logistic regression graph by treatment over time.

Examples

data("substrate")
curve(substrate[,c(3:18)],
      trat = substrate$Trat,
      nrep = 4,
      n=10,
      time = 1:16)
