QUESTION

Combine values from duplicated rows into one based on condition (in R)

Asked 2021-Jun-15 at 16:51

I have a dataset with the name of Danish ministers and their position from 1990 to 2020 (data comes from dataset called WhoGovern; https://politicscentre.nuffield.ox.ac.uk/whogov-dataset/). The dataset consists of the ministers name, the ministers position, the prestige of that position, and the year in which the minister had that given position.

My problem is that some ministers are counted twice in the same year (i.e., the rows aren't unique in terms of name and year). See the example in the picture below, where "Bertel Haarder" was both Minister of Health and Minister of Interior Affairs in 2010 and 2021.

I want to create a dataset, where all the rows are unique combinations of name and year. However, I do not want to remove any information from the dataset. Instead, I want to use the information in the prestige column to combine the duplicated rows into one. The observations with the highest prestige should be the main observations, where the other information should be added in a new column, e.g., position2 and prestige2. In the example with Bertel Haarder the data should look like this:

(PS: Sorry for bad presenting of the tables, but didn't know how to create a nice looking table...)

Here's the dataset for creating a reproducible example with observations from 2010-2020:

Reshape the data to wide format twice, once for position and the other for prestige_1, and join the two results.

Overlay histogram with multiple density curves for generalized pareto distribution

I want to draw an overlay histogram with multiple density curves for generalized Pareto distribution. As you can see that the density curves are not clearly visible. Are they any way to make it clear? Thanks.

There is no "upsert" operation for objects in arrays. If you need to make changes to that array, you will have to read the document, modify the contents of the array in memory, then update the document with the new contents of the array.

Arrays of objects usually do not work the way that people want, given their limitations on querying and updating. It's usually better to store data as documents in a nested subcollection, so they can be more easily queried and updated by the contents of their fields.

Postgresql choose between two selects and same value on different columns

Asked 2021-May-03 at 18:32

I have three tables

Person

employeeNumber name last_name EN12345 Joe Pilgrim EN98764 Eva Snow

Cashier

employeeNumber socialNumber insuranceNumber EN98764 SN98764 IN98764

Manager

employeeNumber socialNumber insuranceNumber EN12345 SN12345 IN12345

I need to join this tables into a new table Employee

employeeNumber name last_name socialNumber insuranceNumber EN12345 Joe Pilgrim SN12345 IN12345 EN98764 Eva Snow SN98764 IN98764

I have no problem on the part of the name and last name, but I don't know how to do the rest. I have a vague idea, something like:

SELECT cashier.socialNumber, cashier.insuranceNumber OR manager.socialNumber, manager.insuranceNumber FROM person INNER JOIN cashier ON person.employeeNumber = cashier.employeeNumber OR INNER JOIN manager ON person.employeeNumber = manager.employeeNumber

I know this cannot be executed like this, but I don't what to use.

You can do it with the $event parameter. Make sure to compare your values safely.

If your value is not in the right type or has spaces or unwanted chars, this c.state == val might not work.

You can use the trim function to compare your value safely: c.state.trim() == val.trim()
