data_readme "com_simplified_geom" is incomplete

[cesarkero]

First of all, this is a great job.
While understanding the functions and logic through the readme, I found and stop point here:

#Joining commune IDs to nodes
df2<-left_join(df2,ndcom[,c("id_noeud","com")],by=c("origin"="id_noeud"))
#Joining 2SFCA to shapefile
com<-left_join(com,df2[,c("com","sfca")],by=c("INSEE_COM"="com"))

The left_join can't be done because the "com_simplified_geom.shp" (com) doesn't contain the attributes to link ID's with the real coords, so I can't generate the map.

Best regards.
