R//ggplot2: Dynamic title when combining facet_wrap and for loop
问题 I have a spatialtemporal dataset with various indicators for a set of location that I wish to map overtime. Here is my facet_wrap + loop #basemap basemap <- ggplot() + geom_sf(data= country_adm2) + coord_sf() + theme_void() print(basemap) #joining dataframe to polygons df_poly <- left_join(country_adm2, df, by= "County") ##joins the data by County. #loop & facet_wrap plots ## This goes over the dataset (df_poly) to plot the the three variables, and facet_wrap over ~Date to see time variation
