then convert each dep
and arr
columns to list, finally add them to get a single list, but while adding check if the item already exists in dep
column for given index, you can use list comprehension for that, and finally join the strings, rename the column, at last merge
the it back to original dataframe.
QUESTION
I am trying to test which variable's sign is going to change (either + or -) after I remove another variable from lm()
in R.
Here's my data:
ANSWER
Answered 2021-Jun-11 at 07:30Tip run your code line by line, to find the exact line that causes the error. In case of a for-loop you can set i <- "T1
and run the lines in the for-loop separately.
In this case the problem is with the get(i)
. That is because there is no variable T1
. That variable exists only in a data.frame. To build formula from strings I usually use paste
combined with as.formula
. So

QUESTION
I have a table of historical data (#Records); at the end of a sproc I need to fill the data against a table of dates (dbo.MasterDates
). For the following simplified example, I'll simply use City as the identifier for a unique series of data.
tempdb.dbo.#Records:
Date City Value 2021-06-04 LA 10.5 2021-06-04 NYC 11.2 2021-06-05 LA 9.2 2021-06-06 NYC 8.1dbo.Dates:
Date Year Month Day 2021-06-04 2021 6 4 2021-06-05 2021 6 5 2021-06-06 2021 6 6If the data was filtered so there was only one series being retrieved (i.e., only data for NYC), filling would be a simple select from dbo.Dates and a left outer join
on #Records. However, I need to fill such that there is a record for each day, for each unique City.
e.g. (filled records bolded)
Date City Value 2021-06-04 LA 10.5 2021-06-04 NYC 11.2 2021-06-05 LA 9.2 2021-06-05 NYC 0.0 2021-06-06 LA 0.0 2021-06-06 NYC 8.1My first attempt was to create a version of the dbo.Dates with records for each unique city, and then use this to fill the #Records table:

QUESTION
I have the following tables:
...ANSWER
Answered 2021-Jun-01 at 17:17The data structure here isn't perfect, hence we need some extra code to solve for this. I needed to gather the amount of cars in each location, as well as to allocate the amounts for each invoice, depending on whether or not it was assigned to a location. I broke out the totals for each invoice type so that you can see the components which are being put together, you won't need those in your final result.
QUESTION
The tests in my project were working fine when I first started using them, currently they have stopped working at all.
Whenever I use the test command the following error is thrown:

package contains tests, like array.test.ts

QUESTION
I am trying write unit test cases for NodeJS Serverless REST API in Mocha and Chai. The API has database calls in it to Postgres database. So I am trying to use the same database (local Postgres database) that I have used to develop the functionality.
In serverless.yml file, environment variable is set like below
...ANSWER
Answered 2021-May-25 at 17:43Mocha doesn't invoke the Serverless Framework, so those variables are never parsed from the ENV file (because the serverless.yml
file is never read/interpolated).
Instead you should use something like dotenv to parse that file and set variables in your test environment. Or just manually set a few directly on process.env
in a beforeAll()
function.
QUESTION
So I have managed to create these sections on my web page, each with an image and some text in them. However with these boxes, the text element (eg. text-lifestyle), is not positioning correctly where I want it to go? Is there a way of fixing this please... I am trying to get each text part either to the left or right of the image, positioned in the centre of that side of the box.
...ANSWER
Answered 2021-May-22 at 15:10I see you're using display: table
. I would advise against using this because it is basically impossible to make your website responsive in a good manner. Rather than using display: table
try using display: grid
. More on css-grid here: https://css-tricks.com/snippets/css/complete-guide-grid/
Concering positioning elements on your webpage, a combination of css-grid and flexbox is the best and easiest way to achieve this, more on flexbox here: https://css-tricks.com/snippets/css/a-guide-to-flexbox/
