QUESTION

How to include a new geography in this table?

Asked 2021-Nov-09 at 21:12

I got this code from someone else and so only know the basic framework. However, to reproduce this you would open a new R markdown document, delete everything below the YAML, and then paste in this. The items in bold below have to be moved to the left for this to knit.

My question is this, how would I bring the United States into the table as a 11th item? Would I do this action in the jolts section or the subtable? United states is code "00". Every state has a two digit state code with the US being "00"

So the solution is two parts.

First, put the following code in after the four jolts elements.

QUESTION

Is there a fix/workaround for making erdJs work with Angular 12?

Asked 2021-Oct-21 at 19:25

Angular 12 seems to have migrated to Webpack 5 and that seems to make the build using erdJs not work, at least in my case.

I've managed to find a few workarounds, including installing crypto-browserify, stream-browserify and path-browserify and using those in my tsconfig.json paths but I still seem to be missing "fs" and getting this Error when running ng build or ng serve

/node_modules/@elrondnetwork/bls-wasm/bls_c.js:54:30-43 - Error: Module not found: Error: Can't resolve 'fs' in '...\node_modules\@elrondnetwork\bls-wasm'.

This error occurs 5 times in 4 other files located in erdjs:

ANSWER

Answered 2021-Oct-12 at 18:40

For others coming to this question in the future. Currently there is no way to use the erdjs npm package in an angular project.

The current workaround involves compiling the erdjs package to its browser version and using that as an asset in the project.

You can compile it yourself by using yarn run compile-browser

The workaround is further described and showcased here: https://github.com/ElrondNetwork/elrond-sdk-erdjs/issues/79#issuecomment-940872053

Read CSV using pandas

Asked 2021-Oct-19 at 19:55

I'm trying to read data from https://download.bls.gov/pub/time.series/bp/bp.measure using pandas, like this:

...

ANSWER

Answered 2021-Oct-19 at 19:55

It's definitely possible, but the format has a few quirks.

As you noted, the column headers start on line 2, so you need skiprows=1.
The file is space-separated, not tab-separated.
Column values are continued across multiple lines.

Issues 1 and 2 can be fixed using skiprows and sep. Problem 3 is harder, and requires you to preprocess the file a little. For that reason, I used a slightly more flexible way of fetching the file, using the requests library. Once I have the file, I use regular expressions to fix problem 3, and give the file back to pandas.

Here's the code:

How to parse unstructured data (i.e. from an HTML directory listing) using JSOUP?

Asked 2021-Oct-12 at 07:57

As an example https://download.bls.gov/pub/time.series/ shows date/ timestamp / filesize information that doesn't appear to be enclosed by HTML tags. If we'd like to consider the date and timestamp information related to each link, what are ideal techniques to capture this information using JSoup.

...

ANSWER

Answered 2021-Oct-06 at 10:16

There are some debates whether this sort of information can be parsed efficiently - Getting directory listing over http.

But if we examine your concrete example, we observe the following:

your file/folder metadata are stored as TextNodes inside the pre element,
every relevant file/folder link (a element) has a direct sibling br that precedes it. Well, except for the root directory: https://download.bls.gov/. You have to treat that case separately.

This constitutes enough information for efficient queries:

The reader works well but you don’t have the right number of columns in your header. You can get the other columns back using .reset_index() and then rename the columns:

What am I missing on how to change the df.to_csv outfile name for looping through a folder?

Asked 2021-Aug-25 at 22:56

I have a folder of 16 files and instead of doing it manually every quarter (names will change) I want to write a script that reads in space delimited data and outputs comma delimited. The input files are .out and the output I want are .csv but with some of the name removed for example: bls_2.out ---> bls.csv

'''

ANSWER

Answered 2021-Aug-25 at 22:56

It looks like you have to remove the file extension before writing a new one. This can be done with os.path.splitext. Also, to get the .csv in the original directory, you'll have to join those paths.
