\title{Replacement of rounded zeros and missing values.}
\usage{
impAll(x)
}
\arguments{
\item{x}{data frame}
}
\value{
The imputed data set.
}
\description{
Parametric replacement of rounded zeros and missing values for compositional
data using classical and robust methods based on ilr-transformations with
special choice of balances. Values under detection limit should be saved
with the negative value of the detection limit (per variable). Missing
values should be coded as NA.
}
\details{
This is a wrapper function that calls \emph{impRZilr()} for the replacement
of zeros and \emph{impCoda} for the imputation of missing values
sequentially. The detection limit is automatically derived form negative
numbers in the data set.
}
\note{
This function is mainly used by the compositionsGUI.
