发帖数: 273 | 1 I need to load data from a .csv file and then save it in a dictionary in R.
The data format:
country,region,value
Each row may have different country and region.
I need to save the value with the same country and region together.
Any help would be appreciated. |

Python or perl is better for these kinda tasks.
