Hi,
Is it possible to create plots after using group by function

Hi, the video is very clear, thank you! I have a question about the function "summarise": ist it possible to insert a goodness of fit check? I would like to group my data and then check for each group of the values of a variable are normal distributed. Would it be possible with the function "summarise" or is there any other way to get it? Thank you in advance!

Salut! Avec ton léger accent, j'en ai dédui que tu étais Québécois ;) J'aurais une question pour toi!
Dans mon DF, mes variables de ligne sont des entreprises (1 entreprise a plusieurs lignes, comme c'est le cas de la sorte de lys qui a plusieurs lignes) et mes variables de colonnes sont binaires (0/1). Je souhaite donc combiner mes variables de colonne en somme (au lieu de moyenne dans ton exemple). Je suis capable de le faire avec la formule suivante :
by_company <- group_by(test_sans_tweets, username)
sum_by_company <- summarise(by_company, sumlocal = sum(Local))
Cependant, j'ai plus de 500 colonnes. Y a-t-il un moyen de faire cette formule avec toutes les variables en même temps pour ne pas avoir à la copier-coller 500 fois? Merci beaucoup :)
