            Update different values in a column based on multiple conditions
            Asked 2022-Mar-10 at 04:27

            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 Nut

            So far I have tried this, but I am not able to change the rest of the columns without any criteria words to 'Other'

            Why does Perl's Devel::Cover think some branches and conditions are not covered?
            Asked 2021-Nov-06 at 05:49

            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 05:49

            The 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

            Regex for replacing commas only within brackets
            Asked 2021-Sep-16 at 13:46

            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.

            1) 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

            Why does this query function returns incorrect results?
            Asked 2021-Aug-07 at 13:25

            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

            .* 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 name B2&"$"

            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.

            You 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:

            When you click on one of the children, you need to access it via event.target.
