Wow!
I've to try it!...thanks

Any link for this?
Seems interesting....

A minimum of bade R. Recognise objects (vectors, dataframes, list) is important

Genial!!!

Si el aburrimiento te lo permite... 😉

¿Con código en R para simularla?

No sé que impacta más, que midan las horas del sol "al mes" o que la escala no llegue ni a las 200 hrs... 😂 😂

Do the summarise() function also a "by" argument?

My first think was to go with tidyverse. However, will depends on what will be her first step and daily usage.
If she only needs define a project (.Rproj) and load a dataframe (.csv, .xlsx, etc) tidyverse is fine.
Doing something else (stats modeling, collaboration, etc) a minimum of base R though.
