QUESTION
Apologies in advance, but I'm new both here and to R. What I'm trying to do is automate adding a column into a data frame that is filled with the actual name of the data frame. For example, if I have the following data frame:
...ANSWER
Answered 2021-May-18 at 21:02If I understand correctly, you want to extract the names of a number of (nested) list members, then assign a column into a dataframe contained in that list member.
This is a quick and dirty solution using example data. It is not best-practices, but it will do in a hurry. Note the <<- to travel up the various environment levels until you find the list in the global environment.

In particular, I am trying to customize a .ctt file from the Curriculum Course Scheduling example file to fit my own school's timetable scenario. I could not find any documentation on customizing a .ctt file for import. If you advise another approach, I welcome alternatives. I appreciate any guidance as I am approaching the tool with minimal Java experience. Many thanks!

Resources for Verifying Translations:

300 DNA chars -> 100 protein chars.
...ANSWER
Answered 2021-Mar-31 at 09:38I think the issue is with you mixing up variable names - your translation code appends to protein but you print output_protein which I assume is actually created somewhere else in your code(?). Also, you first edit the variable dna_sequence but iterate over dna which I assume is also defined elsewhere and maybe doesn't match dna_sequence.
After editing the variable names I can use your code to get the same translation as the NCBI tool.

QUESTION
I have a list of pandas data frames that I got applying the groupby function and I want to add to them a new column with the frequency of each kmer. I did that with a loop but I got a message warning that I need to use df.loc[index, col_names]. Here it is a link to one example of the csv file: https://drive.google.com/file/d/17vYbIEza7l-1mFnavGGO1QjCjPdhxG7C/view?usp=sharing
...ANSWER
Answered 2021-Apr-05 at 12:28It's an error related SettingWithCopyWarning. It's important — read up on it here. Usually you can avoid it with .loc and by avoiding repeat-slicing, but in some cases where you have to slice repeatedly you can get around it by ending .copy() to the end of the expression. You can learn when and why this is important via the link. For a more precise answer for how this is emerging from you'll code, you'll need to show us an MRCE of your code.
QUESTION
As I was bored and wanted to practice my python, I thought I'd write a script that took some genetic code and converted it into the amino acid sequence. It looks through the code one letter at a time and when it sees a certain sequence, starts translating triplets of genetic code into their equivalent amino acid and strings them together until it reaches a triplet of genetic code that doesn't encode an amino acid. The script then goes back to where it started this translation, and restarts iterating through the code until it finds another start sequence.
The script works, up to a point. I started off using a while loop to iterate through the triplets of genetic code after a start sequence, but when it reaches the end of the genetic code, it goes out of range:

QUESTION
writing a function for columnwise computation of sample skewness in Rcpp I'm in trouble using sqrt()-function. I know that sqrt(x) works for NumericVector types (tested it in a separate file), however in my code (where I'm trying to pass doubles) it does not work.
Here's my code:
...ANSWER
Answered 2020-Dec-26 at 17:25To be brief, there are few recurrent and common beginner errors we can avoid:
do not include unneeded headers (mostly harmless, but
Rcppalready brings math headers)do not use a globally flattened namespace
Rcppespecially after you get compilation errors on symbol visibility
With that and the required minimal changes it builds and runs (and returns something non-sensical but I leave that for you to tackle :)
There are other ways to sort this out as std:: symbols and Rcpp symbols generally coexist quite happily with distinct signatures.
QUESTION
I have a problem statement as follows:
In each examination centre, exam is to be organised in two shifts batch I & batch II(reporting time 9:00 AM & 2 PM). Exam can be conducted at any day in a district during December 1-30, 2020 depending upon the number of candidates in a district. Note in each district only one examination centre is possible and in one shift maximum 20 students can appear. Based on the information mentioned above complete the examination database by allocating:
- Rollno: Roll number of the candidate will start from NL2000001 onwards(eg: NL2000001, NL2000002, NL2000003……)
- cent_allot: allocate centre by putting examination city code
- cent_add: put NL "District Name" as center address in each location (for eg if district name is ADI then centre add is NL ADI)
- examDate: Allocate any exam date between December 1,2020 to December 30, 2020 keeping minimum no of examination days and not violating any conditions mentioned above
- batch: allocate batch I or II ensuring all the conditions mentioned above
- rep_time: for batch I reporting time is 9 AM and for batch II reporting time is 2 PM.
As per the above description, I need to make a table which satisfies the above conditions. I have already made the Rollno, cent_allot and cent_add columns, but I am struggling in making the examDate column, since it should have same date for every 40 values of district.
Here is the list of the districts and their frequency of occurrences:
...ANSWER
Answered 2020-Nov-14 at 15:40The key is to use .groupby().cumcount() to get the running number first. The examDate and batch can be subsequently determined respectively by the modulus of the running number against 40 and 20.
Random rows are generated using the given total count for each Dist.

What I'm Trying to do: Make a hangman game using discord.py-rewrite
My Problem: The code stops working after the bot sends (Fruits Category) or (Animals Category) etc. There are no error messages either. I've tried changing def to async def to try to use await ctx.send, but to no avail.

Use await client.wait_for('message') instead. (https://discordpy.readthedocs.io/en/latest/api.html?highlight=wait_for#discord.Client.wait_for)
