[Alejandra Salles <salles@at1.fcen.uba.ar>]

I tried to run a script but i can, and error message appeared in the
screen saying that the operation is invalid but when I did the same
operation in the comands window,  it had not problems.   The operation
that I try to run is a matrix by vector product.  This is the
mathematical operation and the message:

  > scoredata <- sdata %*% singdata$v %*% diag(autodata^-0.5)
  Error in "%*%.default"(sdata %*% singd..: Number of columns of x
should
  be the same as number of rows of y

  If you need more things I can send you the script complete.
  Thank you in advance,
  Alejandra
