Hi,
the typemaps for mapping unsigned int to an appropriate type in
R seem to be broken.
I am trying to wrap a class with constructor
Erdos_Renyi_Network(unsigned int ng, double af,double prob);
Calling network <- Erdos_Renyi_Network(ng=10,af=0.5,p=0.1) results in:
Error in Erdos_Renyi_Network(ng = 10, af = 0.5, p = 0.1) :
REAL() can only be applied to a 'numeric', not a 'integer'
Reviewing the output generated by SWIG reveals that the unsigned int argument is cast into an "integer":
ng = as(ng, "integer");
but the C++ code calls:
arg1 = static_cast< unsigned int >(REAL(ng)[0]);
for the same argument.
Could this be fixed by changing line 45,46 in rtypes.swg to
%typemap(scoercein) unsigned int, unsigned int *, unsigned int &
%{ $input = as($input, "numeric"); %} ?
This removes be cast to "integer" done in R and things seem to work, but I don't know if I am introducing other bugs by this "fix".
Any comments would be appreciated,
Bastian
I am using the SVN revision 10421 of SWIG and R version 2.7.0.
