- .object
An R object of class cSEMResults resulting from a call to

`csem()`

.- .dependent
Character string. The name of the dependent variable.

- .independent
Character string. The name of the independent variable.

- .moderator
Character string. The name of the moderator variable.

- .n_steps
Integer. A value giving the number of steps (the spotlights, i.e., values of .moderator in surface analysis or floodlight analysis) between the minimum and maximum value of the moderator. Defaults to

`100`

.- .values_moderator
A numeric vector. The values of the moderator in a the simple effects analysis. Typically these are difference from the mean (=0) measured in standard deviations. Defaults to

`c(-2, -1, 0, 1, 2)`

.- .value_independent
Integer. Only required for floodlight analysis; The value of the independent variable in case that it appears as a higher-order term.

- .alpha
An integer or a numeric vector of significance levels. Defaults to

`0.05`

.

A list of class `cSEMNonlinearEffects`

with a corresponding method
for `plot()`

. See: `plot.cSEMNonlinearEffects()`

.

Calculate the expected value of the dependent variable conditional on the values of an independent variables and a moderator variable. All other variables in the model are assumed to be zero, i.e., they are fixed at their mean levels. Moreover, it produces the input for the floodlight analysis.
