QUESTION
I'm trying to compare historical daily attendance figures between the Mariners and White Sox.
I created my data frame with MySQL database and whittled it down to these columns: date
, hometeam
, dayofweek
, and attendance.
I then used lubridate
to convert the number that encodes the date into a Date
field in R. I also set the attendance of games reporting 0 to NA. I did both with:

I have a dataset that has several rows and columns, however within the column labeled, 'active', I wish to remove the aggregation and separate this into its own unique count. I also wish to add a column that gives this count a unique id.

Answered 2021-May-13 at 00:25You don't need melt
for this problem and can reindex

with the following. Keep in mind that for the count
column, I realize that if each group has a size > 10
that it would show up as bl010
as an example, when you really want bl10
. The number formatting works with the provided sample data though with group size less than 10, and with group size > 10, it is not clear what the desired output is:

QUESTION
I want to record audio with this code:
sox -d test.wav trim 0 20
but the problem is that it says: sox FAIL sox: Sorry, there is no default audio device configured
and if I try some other sox codes it gives me help of sox.
There is no other way to record audio(Or at least no other way to record audio from command line)?
ANSWER
Answered 2021-May-04 at 11:33SoX 14.4.2 for MS Windows has trouble identifying the default audio device. There are two possible solutions:
- Replace
-d
with-t waveaudio 0
. If you have multiple audio devices (e.g. a USB microphone next to the regular mic plug), then you may need to replace0
with1
or higher. - Uninstall SoX 14.4.2, install SoX 14.4.1 instead.

QUESTION
When I try to read JSON content from a field I get:
WARNING: document 1, attribute assorted: JSON error: syntax error, unexpected TOK_IDENT, expecting $end near 'a:foo'
Here are the details:
This is the (super simplified) CSV file I'm trying to read:
...ANSWER
Answered 2021-Apr-29 at 13:01Well as such a:foo
isnt a valid JSON value AFAIK. LOoks like it meant to be object? So would need {...} surrounding it.
But even {foo:bar}
is not valid either. At the very least the 'value' shoud be quoted {foo:"bar"}
. But really the keys quoting too {"foo":"bar"}
Javascript Objects technically allow unquoted key names, but JSON requires the quoting.
... but also remember it CSV. Quotes are typically used for quoting (eg when columns contain commas), so the quotes need double encoding! Ends up a bit messy...

QUESTION
Like the title says, SQL query which outputs the number of athletes that voted for someone in the same athletePosition as himself.
I have 4 tables in my database right now, they consist of:
...ANSWER
Answered 2021-Apr-08 at 23:49You could accomplish this using an inner join with the same table. In the proposed solution, I aliased one voter
to represent those who casted votes and the other nominated
for those who votes were cast for. The inner join was done on the athletePosition
on both table aliases and voter.votesForId= nominated.athleteId
before finding the total records.
It was difficult to replicate with the shared schema and data however, I believe the StackOverflow community has shared some valuable insights on how to proceed with these in the comments.
I have shared a db-fiddle that replicates your problem and the proposed solution.
