create_psy_fun(psy_fun, guess, lapses)

`psy_fun`	The shape of the function without guesses and lapses.
`guess`	Value indicating the guess rate (leftward asymptote) γ (default is 0). If `TRUE`, the guess rate is estimated as the i + 1 parameter where i corresponds to the number of parameters of `fun`. If, for example, `fun` is a predefined shape with parameters p1 and p2, then the guess rate corresponds to parameter p3.
`lapses`	Value indicating the lapse rate (rightward asymptote) λ (default is 0). If `TRUE`, the lapse rate is estimated as the i + 1 parameter where i corresponds to the number of parameters of `fun` plus one if the guess rate is estimated. If, for example, `fun` is a predefined shape with parameters p1 and p2, then the lapse rate corresponds to parameter p3. If the guess rate is also estimated, p3 will be the guess rate and p4 the lapse rate.
