[R-pkg-devel] [Error] data length differs from size of matrix

[Bill Dunlap]

The offending line in path_coeff seems to be
   betas[i, 2:nvar] <- t(solve_svd(cor.x2, cor.y))
where i is a single integer, nvar is 15, and the right hand side is a 14 by
14 matrix.  What is this line trying to do?  Did it ever give the correct
result?
