I observe 2024 and want to address the relevance of Rstudio or R compared to Python. Taking into account new specializations emerging in 2023 and 2024, such as COURSER's bootcamps, I wonder if completing my current DATA SCIENCE SPECIALIZATION is worthwhile. In 2018, R peaked, but its demand decreased after 2021. I am curious about its practicality now, especially with the growing demand for Python. I am contemplating restarting the JHU specialization, having skipped six courses to focus on practical machine learning. Is it necessary to update the program, and how would this help professional growth with program theories not being updated with what the market still demands in its existing data science roles in 2024? Additionally, I am interested in knowing if JHU is still making updates, or if it's not as important whether it's about Python or R but rather about taking the course for its practicality." Does this certification and its teaching have weight in the market?

Why, between slides 20 and 21, does the (.*) suddenly NOT refer to open or closed parentheses? I.e. the thing being searched for (with anything or nothing in the middle). There are no parentheses in slide 21 but it only means anything between a numeric.
@stewarttoop4031 Жыл бұрын
@gb590212h 10 years ago 2. Slide 20 is misleading because it suggests that the given regular expression will match only lines that contain a "(" followed by a ")" (with 0 or more arbitrary characters in-between). The fact is that that regular expression will match *any* line whatsoever, whether it includes parentheses or not. The regular expression that represents your examples would be \(.*\) or, better yet, \([^)]*\)

for anyone who wanted to know what the hell the attr(, match.length) thing does, it can be used define the vector that describes the length of the matches. In case you have many matches and you wanna display each of them in a string you can label your gregexpr(blabla) as "matches". And that will give you the first vector (the one that tells you where each of your matches begins). matches <- gregexpr(blabla) Then you can call attr() to use the second vector by putting matches INSIDE of attr(). Like this: attr(matches, "match.length"). (because remember your aim/end-goal is to rip out some specific substring and manipulate it to do what you want.) You can then use a for loop to generate out all of your substrings all at once.

In minute 20, you talk about how you might be able to compare analyst quality by their ability to intuitively evaluate counterfactuals on their models/analyses. Good analysts need to efficiently explore their hypothesis space and a lot of time can be lost when they don't have strong experience doing so. Do you think analysts can be misled by their intuition? What are some good methods to fight against past experience creating false confidence? Do you think that using past experience to drive analysis can be dangerous? I feel that educated "guessing" to drive model development has caused a lot of issues in my own work. As an example, when you build a model, you might spend a lot of time fine tuning parameters, and your past experience might be helpful, but, there's a danger in coming to believe that you know how manipulating those parameters will effect outcomes. That's why hyper parameter searching methods exist. I've personally made the mistake of using intuition to take shortcuts in model development, when a better approach would be to write more code to use evidence to drive that search (like grid search).

Hi, Roger, I appreciated your effort and the work you do. I took few advanced courses of statistics, but not with software analysis side. I had a bit of experience with R, but I really want to focus heavily on it from now on. I bought your book "R Programming for Data Science", and it is consistent with the videos. Thank you very much, and I subscribed to your channel. Thanks again for the good work!
