QUESTION
I have a two columns with the following data:
Column 1: BIG123 - Telecommunications (John Barrot)
Column 2: 7 Congressional 1 - Toward
The data format is the same with spaces and the "-" as the delimiter for each column, but the organization, names, and beginning code can be longer or shorter than what you see here(instead of Telecommunications it can be CEO or instead of John Barrott it can be Guy Rodriguez, etc). I need to extract the following:
(Column names are in bold)
Organization Telecommunications
Supervisor John Barrot
Profile Congressional 1 - Toward
I have been using the following cheat sheet but I am still having issues extracting: https://cheatography.com/davechild/cheat-sheets/regular-expressions/
I have tried regex_extract(column1, [A-Z][a-z]) and I only get the first two letters of column 1 after the "-".
Any help would be great.
Thanks,
DW

QUESTION
I am working in the string manipulation with the help of REGEX. I am going through some of the cheat-sheets. I noticed an example
see <- function(rx) str_view_all("abc ABC 123\t.!?\\(){}\n", rx)
What is the usage of function (rx) here ? I am curious to know the answer. Because if i remove function(rx) and give a pattern i get the same answer.
see <- str_view_all("abc ABC 123\t.!?\\(){}\n", "a")
But here i have to use my variable to see my output. Can you please anyone explain?

is the name of the function's argument. Coders many times choose the name x
, probably the most frequent, but the name doesn't matter, just like in a mathematical function you can name it x
, y
, id
or anything you want.
With a function you can pass your variable to it without repeating its code every time you need it.
