How can I arrange a group within a data frame based on year?

Question

I have a data frame ("df") which I want to order based on year for a specific group based on Ticker.

year	Ticker	at
2009	FLWS	286.127
2003	FLWS	214.796
2007	FLWS	352.507
2008	FLWS	371.338
2004	FLWS	261.552
2005	FLWS	251.952
2010	FLWS	256.086
2011	FLWS	256.951
2006	FLWS	346.634
2007	SRCE	4447.104
2009	SRCE	4542.100
2003	SRCE	3330.153
2010	SRCE	4445.281
2011	SRCE	4374.071
2005	SRCE	3511.277

I want to have the data frame in order of year (ascending) for each group of Ticker. I've tried using base R (order) and the dplyr package (group_by, arrange) but I am a complete newbie to any sort of coding so needless to say I have been struggling.

Answer 1

Action function has to have first argument as context then arguments.

Like bellow.

async createUser(context, username, email) {
      await addDoc(users, {
        username: username,
        email: email,
      });
    },

Error you getting is that field username in addDoc() function is object and not a string.

If you enable persistance in firestore you no need vuex. It's just a small tip. Vuex might be only neded if you for example want to store some temporary data like shop cart and you don't want to save them until user will acually buy them. I use vuex if i want to popup some snack on user screan with information like "Success! Data: XXXXXXXXXX was saved.".
