QUESTION

select categories of variable using rstudio addin

Asked 2020-Sep-15 at 19:18

Not knowing where else to ask the question, I ask here (risking downvotes). I have a dataframe, df, with a numeric string code, num, and its associated text label in another string variable, str. The total unique different values here are more than 100.

Now, I´d like to filter approx 50 of these variables, but entering the 50 different values is error-prone and tedious.

Seeing the Rstudio regexplain addin, I was wondering if there is an addin somewhere that accepts a dataframe, allows me to tick a box for the intended variables and finally returns the generated string that I can subsequently use for categorization/filtering.

Is this what you had in mind? The steps are the following:

define the variable df that contains a make column
start the app and make the selection
if you are done, click "stop selection"
my_selection contains the selected values

QUESTION

Confused in capturing groups and using them further

Asked 2017-Jan-20 at 07:14

I was watching lecture about regular expressions and at the time 14:52 she gave to write regex to match the hex codes such as

#abc

#f00

#BADA55

#C0FFEE

So basically the syntax is -:

Start with # sign
The following letter can be range [a-fA-F0-9].
These letters should be exactly of either of size 3 or 6.

I understood the answer

/^#([A-Fa-f\d]{3}){1,2}$/g

But what is wrong in mine regex using group capturing -:

/^#(([A-Fa-f\d]){3}|\2{6})$/

/^#(([A-Fa-f\d]{3})|\2{2})$/

But

/^#(([A-Fa-f\d]{3})|[A-Fa-f\d]{6})$/

is working

I am using this for testing my regex. Thanks in advance

You are using alternation; you can't reference a variable in one branch that you capture in another. A bit more in-depth, on your first failing example:
