Add sp.layout element to plot spplot legend
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
I wish to separately mark NA values for a SpatialPointsDataFrame within an spplot map, and critically to include those points on my legend.
Currently, I am marking the NA values with a red X by mapping the entire SpatialPointsDataFrame as a set of red Xs via the sp.layout option, and then mapping the shapefile again over the top of the red Xs. But I can't figure out how to include sp.layout items within the legend. And I also don't know how to designate a NA values with a red cross, while also mapping the non-NA values by color.
tzaea_latlon <- read.dta13("PATH/TZMapFlourPrices.dta")
tzdata <- tzaea_latlon[ , c("flourEA", "lflourEA","rnd")]
tzshp = SpatialPointsDataFrame(cbind(tzaea_latlon$lon_modr,tzaea_latlon$lat_modr),
tzdata, proj4string=CRS("+proj=longlat +datum=WGS84"))
tzshape1 <- tzshp[tzshp@data$rnd==1, ]
spplot(tzshape1,zcol="lflourEA",cuts=8,cex = .75,
key.space="right", digits=1,col.regions=brewer.pal(8, "YlGnBu"),
par.settings = list(axis.line = list(col = 'transparent')),
sp.layout = list(tz1))
So I just want to find a way to add red Xs underneath the current legend, and label them as "missing data". The data to reproduce the current map is here: https://www.dropbox.com/sh/mysj7zqrfckb05h/AAAr0VX9Rd0NnCpzhz58MzbPa?dl=0
