QUESTION
I have a large dataframe that's updated every day containing the following:
...ANSWER
Answered 2022-Feb-15 at 16:24Here's a solution using {tidyverse} packages. It's easiest if you just specify a list of what timestamps you care about in a separate vector
. I assumed you just care about the hour but you can change the code if you want to be more granular (e.g. specify HH:MM or even down to HH:MM:SS). Then the rest is just group_by()
summarize()
and then mutate()
to add a total column.
One issue is that it seems like you are sharing example data that doesn't contain the times_of_interest
so the summary returns nothing. Similarly you are sharing data from a single date. In these cases the finally summary may not match your expectation. Therefore I first just looked for unique date/time combos to make sure we had a reasonable expectation on what the output would look like. You can also use table()
to do this.
Aside from these issues, the code below still seems like it will produce the desired result based on the data you've shared.
QUESTION
I have a long list of 190 variables, (they are destination routes). And I want to match, if any of these variables, exist in the array arr
. (It is necessary for my job to have this many variables).
For some reason, the code below does not work. I'm not sure if it's because I have so many variables to check, perhaps the code is not efficient enough?
The route I'm specifically looking for in the array is "ORY-PSA"
, which is route72
.
The only time my code works/returns true, is if I remove all the ||
checks, specifically type in the following code:
ANSWER

variables to an array you could make it way more simple.

QUESTION
trying to combine data from 3 tables into 1 table, ala relational database join. Joining 2 SOLR streams works. But how to include a third stream?
btw. This needs to work with millions of rows. Is this a suitable approach? Hopefully all data does not need to be loaded into memory. Goal is to do most processing in solr and less in application.
Part 1 works:
...ANSWER
Answered 2021-Mar-11 at 13:00A join needs both sides to be sorted by the same key, so in the join you're returning that's not the case - since it's sorted on FagkarakterId
and not on FagId
. Think of these streams as being a, well, stream of documents, where each document at the front of the left stream is consumed while checking if the front document in the other stream matches the join condition:
For each document in the left stream, check if the document at the head of right
matches. Given two streams, left and right:
