Re: [R] Error:non-numeric argument in my function

I thought Stavros' suggestion was going to be to have the error message say what type of offending object was found. If the message said that a list of class 'data.frame' was found (probably the leading case), then that would be much more helpful. Patrick Burns patr...@burns-stat.com +44 (0)20

Re: [R] How do you save in R?

I disagree with Dieter's last point. Whether you use 'attach' or 'load' should depend on whether you want the objects in the file to remain separate ('attach') or mixed into the global environment ('load'). Patrick Burns patr...@burns-stat.com +44 (0)20 8525 0696 http://www.burns-stat.com (home

You need a comma (,) not a dot (.) in your subscripting of the matrix. If I get the question correctly, you want: newTS2 - perm[100, TS2] Patrick Burns patr...@burns-stat.com +44 (0)20 8525 0696 http://www.burns-stat.com (home of The R Inferno and A Guide for the Unwilling S User) onyourmark

Re: [R] Matrix multiplication - code problem

You need to put in calls to 'as.matrix'. It's a bit tricky though -- what you want depends on whether it is the first or second subscript that has length 1. as.matrix(id_y[,,i]) if the second dimension has length 1. t(as.matrix(id_y[,,i])) if the first dimension has length 1. Patrick Burns

Re: [R] Function?

Would your blood still circulate if you take off your heart? That is, the answer is, No, that's where the work is done in the function. If you want to understand the computations that function is doing, then you need to examine the C code that it is calling. Patrick Burns patr...@burns
