Calculating SPI index using R studio | Video Tutorial 

hello I like your video, I would like to modify your Excel because my chronicle 1984-2021 but it gives me Error when I pass 2017

HI Thank you very much for your useful video. I noticed that there is some difference when you were calculating the monthly rainfall values here. I think it should be a monthly rainfall value, not a monthly daily average value. Each monthly value represents the total rainfall amount for that particular month. If possible please check. Thank you so much

Thank you for your great video. Since you have a daily data and you need to convert these to monthly data, you should use SUM function within PivotTable and not average.
