R Extension - "Script terminated abnormally"

MBM

Hey,

 

I want to have a Google Map in Rapidminer by using the R Extension. I read here in the Community that it would be possible to display latitutde and longitude data on a map with the R Extension. First I just want to display a map in RM. And in R it is possible with this code:

 

library(ggmap)
library(mapproj)
map <- get_map(location = 'Europe', zoom = 4)
ggmap(map)

But when I try it with the "Execute R" operator in RapidMiner it doesn't work at all. All I get is this

 

Exception: com.rapidminer.operator.OperatorException
Message: Script terminated abnormally.
Stack trace:

The example Processes with R in RapidMiner work just fine without any problem. What do I need to do? Am I missing something?

 

Best wishes

Hi, you can't display the Google Map in RapidMiner Studio. Your error might be related to "ggmap(map)"

 

That said, you can encode the Lat/Longs and create a Google Map in HTML all within in RapidMiner. @mschmitz has some RM process to do that and I wrote an article on how to encode Lat/Longs using OpenStreetMap here.
