+subsetDropAll(x, ...)
+}
+\arguments{
+\item{x}{Object to be subsetted}
+
+\item{...}{further arguments to be passed to or from other methods}
+}
+\value{
+An object similar to \code{x} containing just the selected
+    rows and columns (for a data frame). Column factors that have
+    one or more levels emptied after the subset, will have this
+    levels droped off.
+}
+\description{
+This function is designed to be used in place of
+    \code{\link[base]{subset}} when you want to drop off all empty
+    levels, of all factor columns in a data frame.
+}
+\details{
+This function works exactly the same way as
+    \code{\link[base]{subset}} but it will drop off all empty levels
+    of all columns that are factors in \code{x}.
