QUESTION
I'm still young to coding and cannot figure out better functions or results to some tasks by myself very often.
I have a question on tracking the original string after using str_extract_all
for a specific pattern.
Here is an example data called "fruit".
index Fruit 1 apple 2 banana 3 strawberry 4 pineapple 5 bell pepperI used str_extract_all(fruit, "(.)\\1")
to extract duplicated consonants, and get "pp", "rr", "pp", "ll", "pp".
Also tracked the original string (of those extracted results) by str_subset(fruit, "(.)\\1")
. Here's what I get.
However, I want to know where "each" extracted result is from. Therefore, using str_subset
cannot capture those results which are from the same string. The following dataframe is what I expect to gain.
I'm not sure if I explain my question clearly. Any feedbacks and ideas will be appreciate.
...ANSWER
Answered 2022-Mar-24 at 11:24Your code already did what you want. You just need to create an extra column to store the output of str_extract_all
, like the following:
Since str_extract_all()
returns a list, we'll need to unnest
the list to become rows.
The final line of the code is to create a consecutive index (since "banana" is gone, index 2 will also be gone).

I have a dataframe column that has a string, which may include several spaces. I want to use separate
from tidyr
(or something similar) on the space after the first time a keyword (i.e., fruit_key
in the sample data) appears, so that I separate the one column into two columns.

Answered 2022-Mar-16 at 16:07If we need to use separate
with sep
, then create a regex lookaround - "(?<=) "
i.e. split at the space that succeeds the fruit_key word and as is not vectorized, collapse
into a single string with |
(str_c
)

QUESTION
I have several data frames that I want to join together. Before I do that, I'm trying to create a function that will let me deal with duplicates in column 1 by using group by and summing up the values in column 2. The issue is that I want to keep the same name for column 2, and I can't figure out how to do that.
For example:

I'm currently attempting to write a function in R that will allow me to calculate all possible pairwise t-tests in a data frame (I'm aware that functions exist that can achieve this, but I would also like to learn how to write the function successfully).

QUESTION
On cell B5 I'm trying to get a TEXTJOIN with delimiter "," of INDEX MATCH to the price range you see on Table B. Because cell A5 contains "Apple" then "$$$" is one of the values I need, also A5 contains "Banana" then "$$" is the second value i need. Finally cell A5 contains "Pineapple" but because "$$$" is already was selected because of apple then no need to add it again.
Any help will be much appreciated.
What would I do if instead of 1 cell like A5, I will have multiple rows like this:
What would I do if I have a SKU that has only some of the Fruits and I have to use the formula based on the SKU?
