Problem in EVEN

[Jeet1994]

When I run the code given by you, I get the following error:

Error in Ulam.Spiral(201) : could not find function "even"

Can you please help me?

Having the same problem. Did you have code defining "even" somewhere previously? Can you add it to this code? Thanks in advance!

Ah, okay, ran this ahead of the Ulam.spiral function and it worked.

even <- function(x) x %% 2 == 0

Thanks for this code!
