[R] Seasonal weekly average

[Shakeel Suleman]

Hi,

I am fairly new to 'R' and would like advice on the following. I want to calculate a weekly average number of reports (e.g. of flu, norovirus) based on the same weeks for the last five years. I will then use this to plot a chart with 52 points for the average based on the last five years; another line will then plot the current year, enabling a comparison of current weekly counts against a five  year average for the same week. I would like some advice on how this can be done in 'R' . My data is disaggregated data - with dates in the format in 01/01/2018.

Thanks

Shakeel Suleman
