- Added ChangeLog
- Bugfix for lod() for the case of small x values (see ChangeLog) - Version 0.1-32 as just submitted to CRAN - Got rid of trunk directory, as I will not find the time to finish what I started there and it may confuse visitors of viewcvs in kriemhild git-svn-id: http://kriemhild.uft.uni-bremen.de/svn/chemCal@31 5fad18fb-23f0-0310-ab10-e59a3bee62b4

-\description{
- Inverse of the arithmetic power function \code{\link{powfunc}} used for
- modelling univariate nonlinear calibration data. }
-\usage{
- ipowfunc(x,a,b)

- Coefficient}
- \item{b}{
- Exponent}
-}
-\value{
- The result of evaluating the function
- \deqn{f(x) = \frac{y}{a}^\frac{1}{b}}{f(x) = y/a^1/b}
- which is the inverse of the function defined by \code{\link{powfunc}}
