Shane McGee McMahon

1 is obviously a numeric quantity, this suggests that p is not numeric. Most likely p is a list of length 1. For example:

> x x

[1] 1

> matrix(0,nrow=x,ncol=1)

Error in matrix(0, nrow = x, ncol = 1) : non-numeric matrix extent

> unlist(x)

> matrix(0,nrow=unlist(x),ncol=1)

[,1]

[1,] 0

Thanks Shane,

It really work.
