I have a dataframe with the columns:
...ANSWER
Answered 2021-May-03 at 14:46I think you need a very clear definition of overlap. If you have [2;7], [6;10] and [7;8], which one overlaps with which one ?
Avoid using input
as a variable name, it shadows the function input()
(to get input from the user)
If you want to select clear overlaps (only the start or the end differs), and you only have at most ONE overlap, here you go:

ANSWER
Answered 2021-Apr-25 at 15:15The difference between to top 5 strings and the bottom 5 is that the top ones end with _code
and the bottom ones end with _app_code
, everything else, in this case, remain the same.
To match all the top 5 strings then you might want to use a negative lookbehind
QUESTION
Doing ETL with BigQuery, I aim at cleaning up some text codes:
The standard syntax of these codes is ABC D123 or ABCD D123 (a group of letters, followed by a space, followed by another letter, followed by a group of numbers).
Some numbers however have a O (capital letter) entered instead of a number 0 (zero). These errors are found at the end of the number sequence: so ABC D56O should become ABC D560.
I tried using regexp_replace()
using a lookbehind assertion such as (?<=[0-9])O
.
However, it seems the r2 library isn't handling lookbehind, see this post from 2013 for reference.
So is there a workaround for this?
...ANSWER
Answered 2021-Apr-22 at 03:48These errors are found at the end of the number sequence
Why not just simply replace O
(capital letter) to 0
(zero) when it is at the end of the code - as it is in below example

Have a RE2 regex as following
...ANSWER
Answered 2021-Apr-08 at 09:15RE2 based solution
As RE2 does not support lookarounds, there is no pure single-pass regex solution.
You can have a workaround (as usual, when no solution is available): replace the string twice with (\d),(\d)
regex and $1$2
substitution:

I'm trying to set up a shiny server on the free tier AWS EC2 to test my app but I can't get all the packages compiled and installed.
e.g. duckdb
in the terminal connected to my instance I paste:
...ANSWER
Answered 2021-Mar-09 at 10:11This is indeed due to the lack of RAM on the free tier VM. Binary packages would indeed solve this. But will see whether we can do something about that as well.
