\title{Explain an atom-pair descriptor or an array of atom-pair descriptors}
\description{

}
\usage{
db.explain(desc)
}
%- maybe also 'usage' for other objects documented here.
\arguments{

\examples{
## Load sample SD file
# data(sdfsample); sdfset <- sdfsample

## Generate atom pair descriptor database for searching
# apset <- sdf2ap(sdfset) 

## Loads same atom pair sample data set provided by library
data(apset) 
db <- apset

## Return atom pairs of first compound in human readable format
db.explain(db[1])
