For transitivity, if P is your incidence matrix of 0s and 1s, then P%*%P has
i,j
entry equal to the number of k with Pik = 1 and Pkj = 1. So you want to
check that when P%*%P has a nonzero (i,j) entry, then Pij = 1 too.
Acyclicity: more generally the nth matrix power of P counts the number of
names() is what you want, if i understand your question correctly.

Each row of the resulting matrix consists of sequences 'x[t]',

It has all to do with a string going over two lines and hence the line terminator is
part of the string. If you close the string on the first line then the command is
just fine.
At least the newer version of the parser allows for embedded newline characters.

Hi all,
If I write
v = vector(mode=numeric,length=10)
I'm still allowed to assign non-numerics to v.
Furthermore, R figures out what kind of vector I've got anyway
when I use the mode() function.
So what is it that assigning a mode does?

It's useful when you need to be certain of the mode of a vector. One such
situation is when you are about to call a C-language function using the

elements) can change the mode of the entire vector. This is why it's
