However, it's best to avoid that ambiguity. I often
test at a command prompt variable names I want to
use. If the response is object not found, then I
feel like I can use it.

Hi, everyone
I am trying to estimate 3 parameters for my survival
function. It's very complicated. The negative
loglikelihood function is:
l- function(m1,m2,b) -sum(d*( log(m1) + log(m2)
+ log(1- exp(-(b + m2)*t)) ) + (m1/b - d)*log(m2 +
b*exp(-(b + m2)*t) ) + m1*t - m1/b*log(b+m2) )
