ulla | A new ESST generator - | Generator Utils library

I want to insert line breaks in a very long string using REPLACE ALL OCCURENCES OF REGEX. Unfortunately it does not work. It inserts the line break only one time at the very beginning then does nothing with the remaining string.

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:

I have the following data:

I'm reading through A Complete Guide to Programming in C++ written by Ulla Kirch-Prinz and Peter Prinz, published by Jones & Bartlett. In it, there is an example of a class (page 246) with what I think is a major problem--not in that it is an error but something I've heard you are never supposed to do:

I have a large dataset that 70k+ rows and several columns with variable data.Also i have a column that has over 5000 factors that i need to use.

Is there any way to speed up the regression as currently it takes over 40mins to run. The only way i think i speed it up would be if i could filter only the factors from the test data into the training data or use a data.table and run the reg from that.

Any help would greatly appreciated.

I was reading a book on c++ (A Complete Guide to Programming in C++ by Ulla Kirch-Prinz and Peter Prinz; ISBN: 0-7637-1817-3) and it mentioned that isupper(), along with islower(), isalpha(), isdigit(), isalnum(), isspace(), and isprint(), are macros for character classification.

I find this kind of weird for two reasons:

1. In the same book, it talks about how, even though macros can have arguments, they are still essentially just placeholder names that are filled in with the definition. This seems weird, since I don't know what kind of replacement text would operate conditionally. That sounds more in line with either a function or a built-in operation (like sizeof).

2. It also seems weird because I've heard some people call these functions, while I've also heard some people call them macros.

Any explanation would be dearly appreciated. I'm moderately new to this, so I'm still trying to figure this all out. Thank you.
