[R] on the output of constrOptim()

[Christophe Dutang]

Dear list,

The following example of constrOptim() where the initial point is the solution shows that the component counts is not a two-element vector as documented in the man page. 

constrOptim(c(1,1), fr, grr, ui = diag(2), ci = c(0,0))

Does anyone have the same behavior?

A possible solution is to put line 69 in constrOptim.R before the first possible break line 67.

Regards, Christophe
