I am trying to export shapefile data from GIS to KML with R and want to specify the appearance of the pop-up window of the KML file when using it in Google Earth. I know of course that it's easily possible within the GIS programs but want to do it with R.
The example below works fine but the pop-up windows don't really look good.
library(raster) library(plotKML) library(colorRamps) col <- getData(country = "COL", level = 1) kml_open("colombia.kml") kml_layer(obj = col, folder.name = "testData", altitude = 100, plot.labpt = F, html.table = paste("Info 1: ",as.character(col@data$NAME_1)," || ", "Info 2: ",as.character(col@data$HASC_1)," || ", "Info 3: ",as.character(col@data$NAME_0)," || ", "Info 4: ",as.character(col@data$TYPE_1)," || ", "Info 5: ",as.character(col@data$ENGTYPE_1))) kml_close("colombia.kml")
I would like specify line breaks e.g. "\n" instead of " || " but that doesn't work with paste. The function cat, where "\n" works fine, doesn't seem to work within the html.table command.
I didn't find any further information or examples regarding the html.table command in the kml_layer function and also tried to solve my problem with the htmlTable-package but didn't have success.
Does anyone have a tip or link with information to solve it?
