[R] equivalent R functions for Numerical Recipes fitxy and fitexy ?

Dear Folks,

We need to fit the model y~x assuming there are random errors in both x and y. Numerical Recipes (Press et al.) have two useful functions, fitxy and fitexy, which handle cases of unspecified and specified errors respectively.

Are there equivalent functions in base R or a installable package? Alternatively, has anyone written a wrapper to provide an interface to a library of Numerical Recipes routines constructed for Linux?

Kind regards,

Marc
