R help - Jan 2013 - solve equations

Hello !
I have a rather mathematical than statistical question. I have a 
formula:  P=R*T/(v-b) -a/(sqrt(T)*V*(V+b)) and I want to solve the 
equation for V , in terms of V= ..... Is this possible with R or have I 
to use another program perhaps octave?

  thanking you in anticipation

Claudia

Have a look at uniroot.
Since this is a single equation there is probably no need to look at more high
powered alternatives such as packages nleqslv or BB.
And since you can rewrite your formula a quadratic you can also solve it  with a
simple function.
