Hi,
I met a probem recently and need your help. I would really appreciate it.
I kept receiving the following error message when running a program:
'Error in svd(X) : infinite or missing values in x'.
However, I did not use any svd function in this program though I did include the function pseudoinverse. Is the problem caused by doing pseudoinverse?
Where did you find that function? It is not part of R as it ships, and it *may* be part of GeneTS, where it calls svd after squaring the matrix. But there are simpler pseudoinverse functions (e.g. ginv in MASS) that will not introduce that error.
The tool you needed was traceback(): try it to see what it tells you here.
