QUESTION
I'd like to update values in a column ['D'] of my data frame based on the substrings contained in column ['A']
I have dataframe df, where column D is an exact copy of column A. Column A has list of different cereal names. But I want to check if A contains a certain word and if so, then column D updates to show that word.
For example, If A contains the word Bran then D should update to show Bran. And if column A contains none of the criteria we are looking for then it should return Other.
name Type of Cereal Bran Cereal Bran Fiber Cereal Fiber Nut Cereal NutSo far I have tried this, but I am not able to change the rest of the columns without any criteria words to 'Other'

QUESTION
I have this function which takes an array, counts how often each item occurs, and returns an array of unique items, ordered by count first, then alphabetically sorted, and then alphabetically case-insensitive so that order does not change between runs.
...ANSWER
Answered 2021-Nov-06 at 05:49The problem for the coverage is that it never has both the same count of the two items it compares (the <=>
condition to be 0
) and that they are the same (the first cmp
condition to be 0
).
For that we'd need to be comparing an element to itself, but the sorting routine works with keys from the frequency count, not with array elements -- so there is no two of any one element! So an element is never compared to itself and the first two conditons can never both fail.
One resolution: sort by the actual elements, then select unique ones.
As for the branch failure, I can't quite pin it down right now but a practical (working) solution is to disengage those tests. Altogether†

QUESTION
I have an ingredient dataset and each row is a list of ingredients that's separated by comma, for example:
Oats (24%) (Rolled, Bran), Coconut (13%) (Coconut , Preservative (220, 223)), Brown Sugar, Milk Solids, Golden Syrup (10%), Seeds (9%) (Sesame , Sunflower), Margarine (Vegetable Oil, Water, Salt, Emulsifiers (471, Soy Lecithin), Antioxidant (307)), Glucose, Milk Choc Compound (5%) (Sugar, Vegetable Oil, Milk Solids, Cocoa Powder, Emulsifiers (Soy Lecithin, 492), Natural Flavour), Natural Flavour
I want to parse the file to replace only commas within brackets with a semicolon. There can be any number of brackets and any number of commas within the brackets. The result should look like this:
Oats (24%) (Rolled;Bran), Coconut (13%) (Coconut ; Preservative (220; 223)), Brown Sugar, Milk Solids, Golden Syrup (10%), Seeds (9%) (Sesame ;Sunflower), Margarine (Vegetable Oil; Water; Salt; Emulsifiers (471; Soy Lecithin); Antioxidant (307)), Glucose, Milk Choc Compound (5%) (Sugar; Vegetable Oil; Milk Solids; Cocoa Powder; Emulsifiers (Soy Lecithin; 492); Natural Flavour), Natural Flavour
Can I get some help on regex that will solve the problem? Thank you in advance.
...ANSWER
Answered 2021-Sep-16 at 13:461) gsubfn This can be done without complex regular expressions using gsubfn. The regular expression consisting of a dot matches a single character. Then for each string in the input character vector the pre
function initializes the counter k
to 0 for then for each match fun
is run with that character passed to it via the x
argument. Within fun
the counter k
is incremented by 1 each time a (
is encountered and decremented by 1 each time a )
is encountered. If the counter is not zero and a comma is encountered a semicolon is returned to replace the comma; otherwise, the input character is returned. This is vectorized, i.e. it also works if the input s
is a character vector in which each component should be processed separately.
QUESTION
I have a sheet with First Name Variants on one tab and a search table called "Import" on another. I used a Query function
=if(B4="","",QUERY('First Names'!B:C, "Select C where B matches '.*"&B4&".*' limit 1",0))
on the Import tab to return column C on the First Names tab by looking for a partial match in column B.
However, if I type in the name Jon, it returns Jo Video instead of John Video. It does this because of the name Jonnelle on the row of Jo video.
Another thing, if I type in the name Bran, it returns Branch Video even if the name Bran is not in the entire list. I want to return an N/A error instead.
So my question is How to structure the query formula or other formula to do the job correctly?
Here's a link to the sample sheet: https://docs.google.com/spreadsheets/d/1ymK9fdfl9Me0QU5OhM44K3RRaXnZ6rTSQXKOyAO1cFc/edit?usp=sharing
Here are some screenshots of the sheet:

Thank you in advance for answering! Will definitely appreciate it.
...ANSWER
Answered 2021-Aug-05 at 14:52.*
means a string with zero or any length, so Jonelle
matches .*Jon.*
and Branch
matches .*Bran.*
In case you want to exactly match a name, it should fulfil any of the following criteria
- being the first name
"^"&B2
OR after a different name".* "&B2
AND - continue with a different name
B2&",.*"
OR being the last nameB2&"$"

I have a Stata dataset which has six variables with consumed food ingredient codes and their weight in grams. I have another distinct dataset which has food ingredient codes and consecutive calorie per 100 g. I need to replace codes with calorie to calculate total calorie consumption.
How can I do that? (by replacing or generating new variable)
My first (master) dataset is
...ANSWER
Answered 2021-Aug-02 at 17:57I agree with the comment Nick made about it is better to first make this data long. Read why that is a much better practice here: https://worldbank.github.io/dime-data-handbook/processing.html#making-data-tidy
However, it can be done in the current un-tidy wide format if you for some reason must keep your data like that. The code below shows how that can be done.

...ANSWER
Answered 2021-Jun-15 at 13:33You can use correlated sub-queries and check whether the id
column is a substring of the brothers
or sisters
and then use LISTAGG
to aggregate the matched names.
Assuming that you want the name
to be in the same order as the id
are in the brothers
or sisters
lists then you could use:
