I'm trying to learn R. One of my intentions is to do some Monte-Carlo type modelling of road "accidents".
Below, to simplify things, I've appended a little program which does a 'monte-carlo' type simulation. However, it is written in a way which seems a bit un-natural in R. Could someone help me make this a bit more R-ish please?
Or is there a completely different approach I should be taking?
Many thanks in advance, Sean O'Riordain seanpor AT acm.org

x[c] = runif(1, 0, 1);
y[c] = runif(1, 0, 1); z[c] = sqrt(x[c]^2 + y[c]^2);

c <- c + 1;

print(tc/(c-1));
