[R] Help Coding error

[Behaylu Ayalew]

How are you dear Helper?
I am from Africa, Ethiopia , I have faced this type of problem

Error in optim(seq(-3, 3, length.out = k), wle.fit, method = "BFGS",
control = list(maxit = max.it)) :
  initial value in 'vmmin' is not finite

when I want to run RM.w

> wt = beha$wt> rr = RM.w(XX, wt)

library(psychomix)> rr.country1 = RM.w(XX, wt1)

Error in optim(seq(-3, 3, length.out = k), wle.fit, method = "BFGS",
control = list(maxit = max.it)) :
  initial value in 'vmmin' is not finite

when I want to run RM.w

Thank you in advance !
