The syntax of the first command is wrong. Instead of bes[[bes$education]] use bes$education. Square brackets [[]] are to be used with numbers of columns and $ symbol with their names. It's either [[]] or $ but not both.

A simple approach would be to set the message as a bash environment variable inside the python program, and then reference that environment in the bash script. For example, if the python code set the environment variable CURLY_TEXT using bash array syntax:

str.find has a start parameter. You can use that to skip past your previous search result and only find the next occurrence.
You can use open to read the text from a file (pay attention to the example code in the documentation, i.e. use with open("filename")...)

ANSWER

There are 3 issues with your program. First the way you define an override in C++ is by making the function in base class pure virtual. Then you can override the implementation in child class. Since you are defining an array of base class type objects which has no definition, C++ assumes you want to call the functions of base class.

The second issue is that the array indices are out of bound. There can't be an index 2 in an array of size 2.

Lastly when you allocate memory on heap using new, you need to free it up as well, using delete. Failing to do this can lead to memory leaks.

QUESTION

Documentation or code sample for agglomerative clustering

Asked 2021-Apr-25 at 13:56

for my undergraduate research project, I'm looking for an R code for agglomerative clustering. Basically, I need to know what happened inside hclust method in R. I have looked everywhere but don't find a proper way to combine 2 data points that have the smallest distance. I was stuck at developing a dissimilarity matrix after the first phase of dissimilarity matrix generation(literally I have generated the first dissimilarity matrix). I'm not specifying R, if anyone could give me a solution in any language I would gratefully accept that.

...

ANSWER

Answered 2021-Mar-23 at 00:27

When you use hclust in R, all of the information that you need is stored in the output of the function. You can just save the output and read off what you need. However, the output may not be completely transparent, so I will go through a very small example and you can apply the ideas to your data.

To get a small example, I will randomly sample eight points from the built-in iris data and then use hclust on those eight points. Since I don't specify anything different, 'hclust` uses the default complete-link clustering.

ANSWER

Answered 2021-Apr-13 at 17:41

You can see the next page link in the response: "nextPageLink":"?q=&campus=col&academic-career=ugrd&p=2",

So you should use p instead of page.

SQLAlchemy best way to filter a table based on values from another table

Asked 2021-Mar-27 at 12:36

I apologize in advance if my question is banal: I am a total beginner of SQL.

I want to create a simple database, with two tables: Students and Answers. Basically, each student will answer three question (possible answers are True or False for each question), and his answers will be stored in Answers table. Students can have two "experience" levels: "Undergraduate" and "Graduate". What is the best way to obtain all Answers that were given by Students with "Graduate" experience level?

This is how I define SQLAlchemy classes for entries in Students and Answers tables:
