QUESTION
So I'm currently working on my bachelor thesis and I need to code a class hierarchy (using vector and matrix classes) in order to use methods for solving linear systems.
I coded the basic functions for both classes, and even tried them and they were working. But as I started to add more to the code, I noticed that the functions I used for adding elements to a matrix and displaying them basically stopped working although I don't think I modified them in any way (the same functions I used for the vector class still work).
In a way the functions work, because the couts are displayed, but I don't get to input the values at all.
Here's the vector class (and before you say anything, I don't want to use template):

of 'purchase', then create another grouping based on the diff
erence in adjacent 'date' values i.e. checking if the difference is greater than or equal to 10 days, do a cumulative sum, and summarise
the 'sessionID' by pasting (str_c

element of 'date' and last
of 'date' and any

QUESTION
So, I'm a university student and thus I'm often tasked to write short reports (usually a couple of pages) on different topics. Admittedly, using MS Word would be more than sufficient in most cases. However, I still like to give these short documents a nice layout so currently I am using LuaLaTeX and Overleaf with a bit of customization:

QUESTION
I'm trying to import a text file into R which has several columns separated by |
. Here is the first line:
C00088591|N|M3|P|15970306895|15|IND|BURCH, MARY K.|FALLS CHURCH|VA|220424511|NORTHROP GRUMMAN|VP PROGRAM MANAGEMENT|02132015|500||2A8EE0688413416FA735|998834|||4032020151240885624
I used read.table
to read the data:
pc <- read.table(file = source(file.choose()), header = FALSE, sep = "|")
However I get this error message when I execute the code above:
Error in source(file.choose()) : /Users/na/Desktop/Thesis/04_Data/Campaign contributions/indiv16/by_date/itcont_2016_10151005_20150726.txt:1:42: unexpected ',' 1: C00088591|N|M3|P|15970306895|15|IND|BURCH, ^
I went ahead and erased the commas in the dataset but it didn't work either:
Error in source(file.choose()) : /Users/na/Desktop/itcont_2016_10151005_20150726 copy.txt:1:43: unexpected symbol 1: C00088591|N|M3|P|15970306895|15|IND|BURCH MARY ^
Is it because there are multiple words in a column? How could I fix this?

QUESTION
I start to write my bachelor thesis and I am going to implement a web application, the prof. ask me to make a simple chatbot and add it to my application, he recommends using a framework for that.
I am working right now with Java Spring Boot with MySQL Database.
Can someone guide me and tell me a good Chatbot framework that is free of charge (because I am not allowed to pay for my thesis), which is easy to use.
I will be grateful to you very much
...ANSWER
Answered 2021-May-26 at 22:31If you wish to use a free framework you can try this one: https://botscrew.com/blog/botscrew-bot-framework/
It is based on Spring Boot architecture.
There are many chatbots you can use for free, and also you can do your own, but it depends on the complexity of what you are looking.
Another free alternative for non-commercial use is:
