MAX(object, upper = 1000, interval = c(1e-3, 1000))
object |
an object of class 'drc'. |
upper |
numeric. Upper limit for bisection method. Need to be larger than EDx level to be calculated. |
interval |

A matrix with one row per curve in the data set and two columns: one containing the dose at which the maximum occurs and one containing the corresponding maximum response.
