R help - Jan 2002 - Transforming Data to Normal Distribution

Hello,

Are there any functions/procedures/tools under R that help in 
transforming a one column non-normal data into a normal distribution ?

i.e., if it is a power transformation of the form y = x^p (can p
be determined?) or if y = log(x) is the transform ?

Any suggestions are greatly appreciated.

Swami

Dear Swami,

The box.cox.powers function in the car package does unconditional 
univariate and multivariate Box-Cox transformations.
