drmfit {qpcR} | R Documentation |
The same function as drm
, substitutes the former function multdrc
and has been
replicated to 'freeze' its working status for qpcR.
drmfit(formula, curveid, weights, data = NULL, fct, na.action = na.omit, robust = "mean")
formula |
a symbolic description of the model to be fit. Either of the form 'response ~ dose' or as a data frame with response values in first column and dose values in second column. |
curveid |
a numeric vector or factor containing the grouping of the data. |
weights |
a numeric vector containing weights. |
data |
an optional data frame containing the variables in the model. |
fct |
one of the available functions of the 'drc' package. |
na.action |
a function which indicates what should happen when the data contain 'NA's. |
robust |
a character string specifying the rho function for robust estimation. See drm . |
Please use pcrfit
for easy fitting of single curves
and drmfit
in combination with repform
if multiple replicates
need to be plotted or analyzed.
An object of class 'drc'.
