Hello
I use c++ program, what call R-project to solve matrix multiplications. Some
times, I get an error in R:
Error in solve.default(V, R) :
system is computationally singular: reciprocal condition number =
2.20828e-19
Execution halted
After that, the program crash. The code, what i execute, is:
R.assign(arrMeans, string("R"));
R.assign(arrCov, string("V"));
SEXP ans;
int iRet = R.parseEval("solve(V, R)", ans);
Where R - vector of n size and V - matrix of n,n.
Can anyone tell me, what this error means? I have check my matrix and didn't
found this number. Is it because matrix too big?
How can I, at last, avoid program crashing in R (it crash inside parseEval
function)?
WBR,
Dima
