dtf | Simple and compact Date formatting | Date Time Utils library

First create a multiindex mi from the product of Person and Result to keep missing combinations from df. Then count (size) all groups and reindex by the multiindex. Finally, merge the two dataframes use union of keys from both.

Something like this may be?

That's because of the Scanner.nextInt method does not read the newline character in your input created by hitting "Enter" and so the call to Scanner.nextLine returns after reading that newline. There are two options to resolve this issue,

1. Read the input through Scanner.nextLine and convert your input to the proper format you need

The problem you are facing is described in the docstring of display:

In general, you cannot assume that display output goes to stdout (unlike print(x) or show(x)). For example, display(x) may open up a separate window with an image. display(x) means "show x in the best way you can for the current output device(s)." If you want REPL-like text output that is guaranteed to go to stdout, use show(stdout, "text/plain", x) instead.

And the problem is that if you just write dtf the output is displayed using display.

Unfortunately I cannot recommend a simple work-around of this behavior (you could e.g. modify the destination where the display sends its output but then you will get also e.g. terminal escape sequences which I assume you do not want).

For instance Documenter.jl needs to intercept the output to test the REPL results and what it does is quite complex unfortunately, as you can check here.

Maybe there are better solutions, but the simplest one is to do what display documentation recommends, i.e. use show(stdout, "text/plain", x) instead (and just replace stdout with a custom stream).

For instance here you can check how we test output in DataFrames.jl.

PS. If you want to pass a Matrix to DataFrame constructor and want to generate column names automatically add :auto argument for column names, as DataFrame docsting explains:

It is also allowed to pass a vector of vectors or a matrix as as the first argument. In this case the second argument must be a vector of Symbols or strings specifying column names, or the symbol :auto to generate column names x1, x2, ... automatically.

If you need to run external code blocks and fetch their output then the task is simpler. The only assumption is that these code blocks do not use display explicitly (which is unlikely). In this case just use e.g. Suppresor.jl and wrap whole code block in print like this:

%-3s says that you want to reserve 3 character-widths for the ingredient. Obviously your ingredients are a lot longer than that. String.format deals with too-long values by just.. printing them out, which means that all further items get shifted to the right.

Solution is trivial: Update that %Xs to have an X that is at least as large as your longest ingredient.

You cannot extend a plot. You could try to use the trackprice parameter for that purpose.

Your code explicitly assumes the date will have 5 characters in the form mm/dd, but your first input violates that assumption as it is only 1/1. If the date were formatted in all cases with 2-digit month and 2-digit date (i.e. 01/01), your code would work.

You need to use the date parsing capabilities that are built-in to Java (java.time package).

You could return the outliers column from your function and overwrite the column with the bool values of the return.
