Elmer Param and R problem

[iczajka]

hello everybody.
I'm not shure, if it is good formum for my problem, but I try

I am trying to use ElmerParam, but:
example optimisation in R of rosenbrock function from ElmerParam manual
gives me error:
optim(c(0,0),elmer_param)
Error in fn(par, ...) :
CHAR() can only be applied to a 'CHARSXP', not a 'character'

Can anybody help me?

OK. Problem not solved, but bypassed

I did the same work as ElmerParam+R but in Octave with sed
