Re: [R] Code to calculate internal rate of return

Unfortunately, this is not a robust implementation, and is derailed by Error in uniroot(f, c(-1, 1)) : f() values at end points not of opposite sign -- View this message in context: http://r.789695.n4.nabble.com/Code-to-calculate-internal-rate-of-return-tp864645p2231910.html Sent from the R

[R] Code to calculate internal rate of return

Hi all. I am an R newbie and trying to grasp how the simple optimization routines in R work. Specifically, I would like some guidance on how to set up a code to calculate the internal rate of return on an investment project (http://en.wikipedia.org/wiki/Internal_rate_of_return). My main problem
