kandi X-RAY | irr Summary
This repo contains a custom implementation of numpy.irr built from scratch. It is used to compute the [internal rate of return] also called APR, which is useful in a wide range of financial circumstances. What’s wrong with numpy.irr? It’s extremely slow and usually returns nan.

QUESTION
I'm having trouble with needing to filter based on the content within a row in R. For example, my first row of data has the values A, A, A, B, C, C and I want to subset only the columns that have A in the first row. I would usually rotate/transpose my .csv and use something like filter(dataset, col1 == "A") but my data has to be formatted* in a way that I would need to write something like filter(dataset, row1 == "A") which is invalid.
I've used rownames() to at least title row1, but still can't use that within filter()
I'm having some trouble with search terms for this (googling filter by row or filter by column gives me the same results), so any help is much appreciated!
Here is an example of what my data looks like:

QUESTION
I submitted all of my code below for a better understanding. The code is fine, my question is: How can I perfectly show multiple countries with their country name list? I mean: When I change the country name, then the flag image should be changed automatically, so users see the country name and image. I already put many links in my loadFlag() function in my js file, but this is not working. Please help me, how can i do it with my code? Thanks in advance and love from the top of my heart.
...ANSWER
Answered 2022-Mar-02 at 17:43You're loading country flags from flagcdn.com in which each png is named after a two-letter country code that you have in your country_code value.
You just need to update your loadFlag function to properly update the img tag's property values. See the working code snippet below.

QUESTION
I would like to add the prevalence of an outcome to a univariable regression table generated with gtsummary::tbl_uvregression. Is there a way to do this without converting the tbl_uvregression object to a table and calculating it with the dplyr::mutate function as in the example below?
PS: Daniel Sjoberg, thank you for a very helpful package!
...ANSWER
Answered 2022-Feb-11 at 23:13A gtsummary table contains an internal data frame called .$table_body, and you can modify that data frame directly using the modify_table_body() function. In the example below, I calculate the prevalence and format the results to display in the table. I also expose the already existing column exposure, which is the sum of the exposure/followup time. Happy Programming!

This is a bit hard to explain so I'll show an example below, but I basically have two tables and I want to create a new table with a new column by matching what's in the rows of another table. I also want to note that these tables are very large (10,000+ rows).Is there a way to do this in R?

QUESTION
I'm making a simple bit of JSX that returns different text based on the value of a variable passed in from the back end. Although the card is displayed correctly up to and including the {irr}, the code block with the ifs is simply not executing. There are no errors in the build process or browser, and none of the console.log statements are logged either.
I've done this successfully a few times before, even copy-pasting some of the code from another (working) part of the project as the basis of this bit, and it's pretty simple so I'm not sure where to start trying to figure out what I've done wrong here.
Any ideas?
...ANSWER
Answered 2022-Jan-12 at 13:28with this way you have just bringing function inside the jsx, also you should execute using parentheses. But I want to recommend you define another function outside this block for the purpose of decreasing cognitive complexity.

QUESTION
never use cakephp before and we have a project to edit for our client made in cakephp 2.5.
We tried to create a new functionality "Emplois" to add jobs inside the website. We mainly recreate what existed from an other models / controller already working inside the website but currently we get this error and we can't figure the problem.
...ANSWER
Answered 2022-Jan-07 at 14:05As mentioned in the comments, the problem with your code is that it uses non US English names, which violates CakePHP's naming conventions, and breaks the magic around that which is using inflection for tasks like finding and loading the default model for a controller based on singularizing the controller name.
Inflection mostly works on word endings as known from US English based words, it's not like the inflector knows about all possible words, it's just some basic grammar rules and a few exceptions, so things might work for words from other languages simply because their ending happens to match a rule. -ois as in your Emplois name matches the rule for uninflected words, it will catch words like bourgeois or Illinois. Regarding your example from the comments, Projets and Projects, there's no difference for the inflector, it will not match anything irregular, but just the the -s ending rule, and therefore being interpreted as plural, so it happens to just work by chance, so to speak.
Ideally you use proper English names everywhere. If you cannot work that out right now, then the next best thing would be to either use custom inflections, or depending on the situation where inflection is failing, interfer manually, like using loadModel() manually. An example for custom inflection for Emploi/Emplois would be:
