kml_to_sp: Convert kml to polygon

In rWBclimate: A package for accessing World Bank climate data

Description

Create an sp SpatialPolygon or SpatialPolygonDataFrame object from a downloaded KML file and data file

Usage

kml_to_sp(map_df, df = NULL, crs_string = "+proj=longlat +datum=WGS84")

Arguments

map_df	a map dataframe generated from create_map_df()
df	a climate dataframe with one piece of data to be mapped to each unique spatial polygon.
crs_string	Coordinate reference string to use in spatial projection. Default is WSGS84.

Details

If a dataframe is included, a spatial polygon dataframe object is created. The dataframe must have one unique piece of information per polygon, otherwise an error will be thrown. However just a basic spatial polygon will be created if no dataframe is included.

Value

a SpatialPolygon object

Examples

## Not run: 
sa_map <- create_map_df(locator=SoAm_country)
sa_dat <- get_ensemble_temp(SoAm_country,"annualanom",2080,2100)
sa_dat <- subset(sa_dat,sa_dat$scenario == "a2")
sa_dat <- subset(sa_dat,sa_dat$percentile == 50)
sa_poly <- kml_to_sp(sa_map,df = sa_dat)
### colors are a bit off, but just to verify that data is
spplot(sa_poly,"data")


## End(Not run)
