Create a SpatialPolygonsDataFrame for world timezones.
convertOSMTimezones(nameOnly = FALSE, simplify = TRUE)
Name of the dataset being created.
Logical specifying whether to only return the name without creating the file.
Logical specifying whether to create "_05", _02" and "_01" versions of the file that are simplified to 5%, 2% and 1%.
A world timezone shapefile is downloaded and converted to a
SpatialPolygonsDataFrame with additional columns of data. The resulting file
will be created in the spatial data directory which is set with
setSpatialDataDir()
.
There are 2 timezones which have polygons but the associated rows in the dataframe have no data.
These timezones also have no countryCode
assigned. We hope to rectify this in a future release.
These are the missing timezones:
> OSMTimezones@data$timezone[is.na(OSMTimezones$countryCode)]
[1] "America/Nuuk" "Asia/Qostanay"
setSpatialDataDir
