QUESTION
I am going through the "Java Generics and Collections" book by Naftalin. I want to check my understanding regarding a point that they make in Chapter 3.
They explain about how the Comparable interface allows us to control what types we can compare with one another. In the below code example that they provide, they say that it is not possible to compare Apple with Orange. To be precise, this is what they say:
Since Apple implements
Comparable, it is clear that you can compare apples with apples, but not with oranges.
But as you can see, on the last line of the main method, we are able to do so, because the compareTo from the base class ends up being called. So I presume the solution to this would be to duplicate the implementation of the compareTo method by moving it to each of the Apple and Orange classes? And removing it from the base Fruit class? Or is there a better way to do this?
ANSWER
Answered 2022-Apr-17 at 16:54- A class has method
compareTo(Fruit)doesn't mean it implementsComparable. Only the opposite is correct. - In java API, method requiring comparison is based on
Comparableinterface, instead of checking if the class hascompareTomethod.
Since Fruit does not implements Comparable(it is a design problem if it implements), what the book say is correct. You can see Collections.max can't be called with List.
compareTo in Fruit.
- The name is ambiguous to
Comparablemethod,
So by convention, we should name a methodcompareToonly when we implementsComparable. - Wrong method may be called due to static binding
QUESTION
I want to group using Grade and sort in descending order based on the number of elements in each group, then use the Number property to sort each group element in ascending order. I tried but it doesn't work. Can you help me on what I'm doing wrong?
Here is the error content:
The type arguments for method 'System.Linq.Enumerable.OrderBy(System.Collections.Generic.IEnumerable, System.Func)' cannot be inferred from the usage. Try specifying the type arguments explicitly.

That's not what ThenBy is for. ThenBy provides a secondary ordering for the same sequence. It's not meant to perform a sort within items in the sequence. (Additionally, the last part of your lambda expression in ThenBy is List.Sort, which returns void... whereas the compiler expects a delegate that returns "the thing you want to perform secondary ordering by".)
The "outer sequence" ends up being a sequence of groups. If you want to transform each of those groups, you need to use Select. So I suspect you want:
QUESTION
I'm building an Rshiny app that takes user input and generates an Rmd powerpoint slide with graphs. I'm basing this off of the example I found at https://mattherman.info/blog/ppt-patchwork/ . When I try running the example off of Matt Herman's blog it generates the ppt as expected. Yesterday, when I ran my code, I kept getting the error message "Error in +: non-numeric argument to binary operator". I slowly subbed out my graphs/charts/code into the example code, and was able to generate a ppt slide without the error. I thought I was in the clear.
This morning, I tried to run the program again after opening and closing R, and now I'm getting the same error as yesterday, although the Matt Herman example code still runs perfectly. I'm thinking it has to do with the patchwork package loading incorrectly, but I'm such a newbie at R that I'm not 100% sure. If anyone could help, it'd be much appreciated! The inconsistency of this is driving me bananas.
(PS I know the code is a little sloppy right now - I have libraries added on there from past attempts that I probably don't need anymore, I'm just in the middle of writing this and trying to figure out this patchwork issues, so apologies for the clutter.)

Answered 2022-Feb-25 at 17:34The solution (using wrap_elements) has already been provided in the comments, which deserves to be the accepted answer. But I'd like to add a little on why this can produce slightly confusing results, which is not immediately obvious.
Interestingly, the need to wrap_elements seems to depend on the order in which the element are added to the patchwork layout.
This from the linked example code works (last step)

Answered 2022-Feb-12 at 17:23The problem is that none of your specified breaks fall within the range of the data. There is therefore nothing to colour, and so no scale to show.

How do I add label names in the white boxes to each of the three axis on the ggalluvial sankey plot from the dataframe? (see image)
Column "Country" has observations for multiple countries. In the example below I am focused on Ireland which has the label "IE". How do I harvest the dataframe for the Country name using the ggplot code below? I will also be doing this task for the "Vaccine" and the "TargetGroup" names so if the solution can include these columns too, I would be grateful. Thank you

In desktop environment, HTML5 canvas works well. But When I tried to run in mobile environment (Google Chrome Android) I cannot draw anything in canvas.

I want my colours to start at the top left within the color-select (green box), and for some reason the last item is off screen. How do I make it start at top left and all colours contained within the color-select (green box) section?
Also, when the site is in mobile view, how do I make each item (colours) smaller and in a row of six? (I have 12 colours but couldn't display them all here).
...ANSWER
Answered 2021-Jun-30 at 15:35You have much too much css involved for nowdays browsers.
Your first mistakes are to use space-between and then offsets of around 100px your hexagons ... last ones will be average 100px outside the container.
turn space-between to space-around, so first and last element do not stick to the edges.
decrease your offsets of 100px 120px becomes 20px and 80px becomes -20px , this way it remains closer to its origin area .
example from your code (i removed uneccessary parts and moved repeated style into a single group of rules)

I'm using ggplot and I get those weird horizontal lines out of geom_bar. I cannot provide a minimal working example: the same code works with few observations and it relies on data I am importing and transforming. However, I can show the relevant line of codes and cross my fingers someone ran into this issue:
...ANSWER
Answered 2021-Mar-03 at 01:06I'm guessing the lines are due to a plotting bug between observations that go into each bar. (That could be related to the OS, the graphics device, and/or how ggplot2 interacts with them...)
I expect it'd go away if you summarized before ggplot2, e.g.:
