\usage{
one(...)
}
\arguments{
\item{...}{Unquoted column name to pull values from.}
}
\description{
Returns one arbitrary value from the input for each group. The function is
biased towards non-null values: if there is at least one non-null value for a
certain group, that value is returned, and only if all the values are null
for the group will the function return null.
