QUESTION
I have three variables in my dataset (name, age_group, parents_total). parents_total
was measured two times. Now, I would like to usepivot_wider
to keep the name
and age_group
but "compute" a new variable with the t2 result of the parents_total
.
In this example, age_group
may change. If possible, I would like to compute this "t2" variable if age_group
remained the same.
Related topic: pivot_wider issue "Values in `values_from` are not uniquely identified; output will contain list-cols"

QUESTION
I have a 1x10 dataframe where the name of each column is a string in a list. I have a 1x10 row vector with values. I would like to integrate this vector in the dataframe, so that I have the names in the list as column names, and the values of the vector in a single row.
How could I do that ? The only way I found was appending eveything into one column, and rename the index with the names in my list, but I want a 1x10 dataframe instead of a 10x1.

I'm currently using stack navigation on my app, but I decided to increment a Drawer for a user's menu.
I managed to insert the Drawer in my pages, but some of them are a MapView content, so the user can't really drag the menu from the screen... So I decided to implement a button to call the ToggleDrawer function, which is presented in the documentation. But I'm getting the error:
TypeError: navigation.ToggleDrawer is not a function. (In 'navigation.ToggleDrawer()', 'navigation.ToggleDrawer' is undefined)
Here is my map screen where I'm trying to insert the button in like this:

I am trying to find the number of failed passes per player that leads into a turnover by the opponent (thus by an interception). See column type_name
and result_name
, the cases where this happens are in row 43 and 46 (thus row 42 and 45 are the unsuccessful passes and should be counted).

QUESTION
I have a dataframe that contains a foul made by a player which eventually leads to a shot on target. What I want to do is create a new column that puts either TRUE/FALSE, where TRUE is set, if the foul of a player leads to a successful shot on target by the opponent (thus the opposite team of the player that made a foul). This should happen within 120 seconds (from the time_seconds column). Rows 15 and 16 provide an example:
In row 15 the away-team (i.e. home_team == FALSE) commits a foul,
where in row 16, the home-team (i.e. home_team == TRUE) successfully shoots on target.
The timedifference is time_seconds[16] - time_seconds[15]
, which is approximately 99 seconds.
If this occurs, the new column should put TRUE in row 15.

The code is working fine, but my main component is too overwhelmed with the function "renderCadastros".

I'll still have to call the function "removerCadastro" from this parent component when the "renderCadastros" component is created.
