I want to add the price on the graph according to the id (suppose each room has one unique id with it)
id price
1 $69
2 $74
4 $199
is there a way to do this easily with any tools in R?
I think the reply helped me solved how to add the data and put it onto the graph
I need to specify one hard thing regarding this issue Probably the hardest part is to get the coordinate of the cell in the map, I have hundreds of the graphs need to fill in the price data, can R detect the different cells and tell me the coordinate and fill in the price data?
