Hello,
So I took the easy way decided it was close enough to 0. The user proceeded to
run
robjects.r('''
f <- function(r, verbose=FALSE) {
if (verbose) {
cat("I am calling f().\n")
}
2 * pi * r
}
f(3)
''')
which was in "Introduction to RPY2" but instead of 18.85 kept on getting
<FloatVector - Python:0x2f32290 / R:0x2398078>
I'm not sure this has to do with that one test it failed after installation, or
something else. Does anybody know what might be causing this?
Thank you,
--Koji
