You're going to have to give us more to go on than that, but...
Are you an ecologist and you want to estimate the optima and tolerance
range from a fitted logit model? If so, here is an example:
## install.packages("analogue") if not installed
require(analogue)
data(ImbrieKipp, SumSST)
## fit a model
mod <- glm(G.pacR ~ SumSST + I(SumSST^2), data = ImbrieKipp/100,
family = binomial)
## plot it
pdat <- data.frame(SumSST= seq(min(SumSST), max(SumSST), length = 100))
p2 <- predict(mod, pdat, type = "response")
lines(p2 ~ SumSST, data = pdat, col = &quo...
