Question

It seems like a simple thing to do, but none of these elements are appearing in my code (from the summary function() at the end), and I can't fathom why.

Here is the code:

I'm trying to extract a specific value from JSON file.

the key value is: "info": "this is an example" (The key is unique)

I want to extract only the value: "this is an example"

My code:

I am trying to 1st divide up four-letter words based upon the last two letters of the word (suffix) and 2nd count up how many words I have for each of these endings.

I have a list containing 3,164 words called filtered and I have sorted them by their suffixes, which doesn't seem much of a help.

(I want to create a dictionary that takes the suffix as a key and the words as a list but I don't know where to begin!) It would be something like:

OUTPUT:

dic = {'ab': ['Ahab', 'Arab', 'Saab, ...]; 'al': ['Aral', 'Baal', ...]}

and so on. Would that be possible?

I have a data.table A:

So, I have a dictionary with a bunch of keys and values, e.g.

I am trying to get my xml response in the correct format using HttpUtility.Decode. Upon doing and loading it in Xml Document, it is throwing the following exception : Unexpected XML declaration. The XML declaration must be the first node in the document, and no white space characters are allowed to appear before it. Line 1, position 313.

I'm using plot_grid now but should perhaps be using facet wrapping? I'm unsure whether that would allow me to place vertical lines. The code that generates my current plot is here.

Yet again my unfamiliarity with AWK lets me down, I can't figure out how to match a variable at the end of a line?

This would be fairly trivial with grep etc, but I'm interested in matching integers at the end of a string in a specific field of a tsv, and all the posts suggest (and I believe it to be the case!) that awk is the way to go.

If I want to just match a single one explicity, that's easy:

Here's my example file:
