The crypto_box.find() call sometimes fails to find a matching

, so when you call .p.text it gives you the error.

A workaround would be to save the result of the find before trying to access the .p.text as follows:

QUESTION

Retrieving the data for an each element in the vector in R using a loop and assembling a new data frame

Asked 2021-May-02 at 18:51

I have a vector crypto_coins <- c("bitcoin","polkadot","dogecoin") and a function return_chart("coin_name"), which returns some data on a given crypto (e.g. return_chart("bitcoin")).

Daily prices in return_chart are stored in a column prices. For example:

return_chart("bitcoin")[, "prices"] #returns every daily price of bitcoin for last 30 days

I would like to create a FOR (or WHILE) loop, which would allow me to 1) retrieve the data for each currency in the vector and 2) assemble a new data frame Crypto_data. This data frame should contain:

Coin names in the first column.
Average price (calculated as an average of daily prices) for each coin in the second column.
Standard deviation of the average price for each coin in the third column.

Please, let me know how can I create such a loop. Thank you in advance.

First, create the output data frame with initialised columns of zeros for average price and standard error:

How to colSum grouped by date

Asked 2021-Apr-21 at 18:50

I have a large table with a comments column (contains large strings of text) and a date column on which the comment was posted. I created a separate vector of keywords (we'll call this key) and I want to count how many matches there are for each day. This gets me close, however it counts matches across the entire dataset, where I need it broken down by each day. The code:

ANSWER

Answered 2021-Apr-21 at 18:50

As pointed out in the comments, you can use group_by from dplyr to accomplish this.

First, you can extract keywords for each comment/sentence. Then unnest so each keyword is in a separate row with a date.

Then, use group_by with both date and comment included (to get frequency for combination of date and keyword together). The use of summarise with n() will give number of mentions.

Here's a complete example:

The response basically looks like a list of dicts. So to extract names (or other keys) you can just do a list comprehension:

QUESTION

Polkadot websocket API doesn't listen for new blocks

Asked 2021-Feb-25 at 09:24

Im using the polkadot.js api, running from a shell, and expecting to get multiple "Chain is at block #12345" messages. But i only get 1 of these messages and I do not know why.

I'm running a Polkadot node using the following docker command:

docker run -it -p 30333:30333 -p 9944:9944 -p 80:9933 -v /mnt/polkadot:/polkadot/.local/share parity/polkadot:latest --rpc-external --rpc-cors=all --chain westend --ws-external

and am following the examples in the polkadot.js api documentation

If i stop the docker container and then restart it i get 1 more message, so i know the connection is still open. it seems like the node isnt emitting the messages.

If I query wss://rpc.polkadot.io instead of my node (on port 9944) I get the expected behaviour.

Can anyone suggest a solution or steps to investigate?

...

ANSWER

Answered 2021-Feb-25 at 09:24

The problem seems to be due to the node syncing with the network.

The node finished syncing the Westend network an hour ago and the API is now working as expected.
