Slope and inflection points for the eHOF model types.
Para_deriv(
resp,
newdata = NULL,
model = NULL,
p,
type = c("slope", "inflection"),
...
)For slope a vector of slopes for all newdata points. Inflection points are the extremes of the second derivative.
response model results, see [HOF()].
new gradient vector, if NULL a vector with 10000 values within gradient range will be used.
response model type. If not specified, the output of [pick.model()] will be used.
Vector of model parameters. If not specified, resp$models[[model]]$par will be used.
Output type: slope or inflection points of model curves.
