grc | Tool to colorise stdout/stderr output | Command Line Interface library

I want to write a code that can be used on different XML files (all with TEI encoding) to see if specific elements and attributes appear, how often they appear and in what context). To do this I have written the following code:

I am trying to read cells from .xls file and place them into particular spots in a static text and then have that generated as .txt file.

I managed to write code that generates what I need, but it only works for the first row in the .xls file. It generates 4 files according to the number of rows, but every file has values from the first row. I understand that I have static cell values for the first row in the code, but I am not sure how to amend this and get the code to go row by row/cell by cell and generate relevant .txt file for each row. My guess is that it needs to be incorporated into the for loop somehow?

For context, each row represents one printer, and these files are then used to import the printers into a system.

I'll be glad for any help/suggestions.

This is what my test .xls file looks like

I have a dataset with ~ 150 countries, a grouping variable, and a value for each country and group (0-6). I am trying to show, that countries with a higher GDP get higher values in one group than the other. I made a scatterplot showing the values for each country by group (the countries are sorted by GDP). I want to draw a line around the points, so it becomes more aparent which group has higher values in which range of GDP. I am however, at a loss.

System:debian 11,Gnuradio 3.8.10,python 3.8.10

I try to use meta file sink block to record the raw IQ data with meta data.
grc file as below:

I want to run the application "gnuradio-companion". I can do this without problems by executing sudo gnuradio-companion. But I do not want to run this with sudo. If I try to run without sudo I get the following. Can you help please?

I'm trying to obtain a table of data obtaining just the country, year and value from this World Bank API but I can't seem to filter for just the data I want. I've seen that these types of questions have already been asked but all the answers didn't seem to work.

Would really appreciate some help. Thank you!

I am making a bar plot with ggplot2. For some reason the font created using geom_text looks very different than the rest. It looks 'worse', sort of pixely, and when I paste the pdf in a ppt presenation you can hardly read the geom_text text. The axis fonts look great.
Any help appreciated,

I have a dataset with about 50 columns (all indicators I got from World Bank), Country Code and Year. These 50 columns are not all complete, and I would like to fill in the missing values based on an lm fit for the column for that specific country. For example:

Doing this for a single country and a single column is absolutely fine when following these steps here: Filling NA using linear regression in R

However, I have over 180 different countries I want to do this to. And I want this to work for each indicator per country (so 50 columns total) So in a way, each country and each column would have its own linear regression model that fills out the missing values.

Here is how it looked after I did the steps above: This is the expected output for ONE column. I would like to do this for EVERY column by individual country groups.

However, the data looks like this:

There are numerous countries and columns that I want to perform this on just like the post above.

This is for a project I am working on for my data-mining / statistics class. Any help would be appreciated and thanks so much in advance!

I tried this:

I'm trying to import a module located in AWS codecommit. To clone the repository I'm using HTTPS GRC (Git Remote Codecommit) method, which uses Google Suite credentials to access AWS console.

The command I use to clone the repository is:
