simpler | lightweight wrapper of R

Update: Added a simpler demonstration jsfiddle, https://jsfiddle.net/47sfj3Lv/3/.

reproducing the problem in much less code I'm trying to move away from jQuery.

Some of my code, for populating some tables, has code like this

I am trying to create scatter plots of all the combinations for the columns: insulin, sspg, glucose (mclust, diabetes dataset, in R) with class as the colo(u)r. By that I mean insulin with sspg, insulin with glucose and sspg with glucose.

And I would like to do that with tidyverse, purrr, mappings and pipe operations. I can't quite get it to work, since I'm relatively new to R and functional programming.

When I load the data I've got the columns: class, glucose, insulin and sspg. I also used pivot_longer to get the columns: attr and value but I was not able to plot it and don't know how to create the combinations.

I assume that there will be an iwalk() or map2() function at the end and that I might have to use group_by() and nest() and maybe combn(., m=2) for the combinations or something like that. But it will probably have some way simpler solution that I can not see myself.

My attempts have amounted to this:

Im trying to get the first 2 names in the following example json, without having to call them

test.json

I'm working on a Dataframe which contains multiple possible values from three different sources for a single item, which is in the index, such as:

This issue is related to the same project that I posted another issue a few minutes ago and maybe it's simpler to resolve.

When I click the mobile icon in Chrome console, instead to use the actual size of the mobile it's emulating (in this case an iPhone 10 with a width of 375px) it shows a tiny contents as if I was looking at a desktop layout into a small mobile screen.

Here a couple images from my screen to make it more clear. Notice that the mobile view is just a miniature of the desktop view while I would like that it adapt the layout to the smaller width.

HOWEVER if instead clicking onto the mobile icon I just drag the console window to the left and squeeze the viewport manually it will work as expected and will redistribute the content correctly. See:

Here is my HTML and CSS code:

I want to do a simple string transformation on the output of an activity in Azure Data Factory. I can use a Databricks notebook of course for that, but I would like to have a simpler and lighter solution. Is there any built in activity in Azure Data Factory specifically for this purpose?

Given I have the following TestFixture with TestCase arguments as pairs of decimal, int (because C# doesn't support decimal directly in an attribute).

I was taking freecodecamp.org course on JavaScript data structures, going through the RegExp chapter. I then came across the following assertion:

"The regular expression /(?=\w{3,6})(?=\D*\d)/ will check whether a password contains between 3 and 6 characters and at least one number". (Here "check" meaning that regExp.test(password) returns true)

This seems odd to me. First of all, looking around in Stack Exchange, I found in this post that states that A(?=B) is the definition of positive lookahead, and it makes no mention that A (the preceeding expression in the parenthesis) is optional. So, shouldn't freecodecamp's example have an expression before the first lookahead?

I believe that this another example is quite similar to the previously mentioned, but simpler so I will mention it in case the explanation is simpler, too:

Why does (?=\w)(?=\d), when checked against the string "1", returns true?, Shouldn't it look for an alphanumeric character followed by a numeric character?

PS: After a thought, I hypothesized that my first example checks both lookahead patterns independently (i.e. first it checks whether the string is made of three to six characters, returns true, then checks whether there is an alpha numeric character, and finally since both searchings returned true, the whole regexp test returns true). But this doesn't seem to be coherent with the definition mentioned in the post I've linked. Is there a more general definition or algorithm which the computer "internally" uses to deal with lookaheads?

I'm making mysql SP, which has an input of type VARCHAR(20).

What I want to do is to convert the last character of input string to a number.

However last character can be number or letter, so if it is number, converting is not needed.

For example, input 'APPLE' will be converted to '5' because 'E' is 5 in alphabetical order, '123' will be '3', and 'BANANA' will be '1'.

To do this, I splitted last character but don't know how to convert.
