http://had.co.nz/reshape/ please, do at least some effort before you post a question, so people don't have to point out that your question can easily be solved by reading the f*cking manual. cheers Joris On Fri, Jun 18, 2010 at 3:39 PM, n.via...@libero.it wrote: > > Dear list, > I'm looking fo

Re: [R] Inverse function

This is not a homework problem. How to solve numerically for y from f(y,r) - a=g(y)=0? I am not too sure. Thanks! Hannah 2010/2/24 Bert Gunter > 1. Is this a homework problem? > > 2. Etiquette on this list is to sign with your full real name. Adhering to > the list etiq

Re: [R] Inverse function

1. Is this a homework problem? 2. Etiquette on this list is to sign with your full real name. Adhering to the list etiquette may enhance your chance of a useful response, especially in view of (1), as we (or at least some of us) do not wish to do students' homework for them. 3. Hint: f(y,r) = a
