[Rd] invalid operands of types ‘SEXPREC*’ and ‘R_len_t’ to binary ‘operator/’ with Rcpp.

2013-05-14 Thread Xiao He 
Dear R-Developers,

I just started learning how to use Rcpp. Earlier while using it, I
encountered an error as shown below:

file74d8254b96d4.cpp: In function ‘Rcpp::NumericVector
foo(Rcpp::NumericVector, Rcpp::NumericVector, Rcpp::NumericVector,
Rcpp::Function, Rcpp::Function)’:
file74d8254b96d4.cpp:10: error: invalid operands of types ‘SEXPREC*’ and
‘R_len_t’ to binary ‘operator/’
make: *** [file74d8254b96d4.o] Error 1

Below is a mock function that can reproduce this error. I wonder if anyone
can tell me what is the problem here. Thank you in advance!!

foo-cppFunction('
   NumericVector foo(NumericVector q, NumericVector shape1, NumericVector
shape2, Function pbeta, Function sequence){
 NumericVector output(q.size());
 output=pbeta(sequence(q.size())/q.size(), shape1, shape2);
return output;
 }
 ')


Best,
Xiao

Please use the appropriate mailing list (Rcpp-devel) for Rcpp questions.
