tile source (e.g., "water", "earth", "roads").}

functions (e.g., \code{\link{pmPolygonSymbolizer}},

\code{\link{pmLineSymbolizer}}).}

|
\item{minzoom}{Numeric. Minimum zoom level at which this rule applies.
|
|
Default is NULL (applies at all zoom levels).}

\item{maxzoom}{Numeric. Maximum zoom level at which this rule applies.
|
|
Default is NULL (applies at all zoom levels).}
|

|
|
\item{filter}{Character. A JavaScript expression string that filters
|

features. The expression has access to \code{zoom} and \code{feature}

\description{

|
Creates a paint rule that specifies how to render features from a
|

particular data layer. Paint rules control the visual appearance of
|
|
polygon, line, and point features.

|
|
# Render water polygons in blue

# Filter to only show highways
