\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 coordinates 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.
