QUESTION
I am trying to do a paired t.test
on my data for pre-post analysis and uses gtsummary
package to create the table. As I have missing data I filter
the dataframe by complete.cases(.)
but as it filter for all the columns I am loosing much data. Instead of that I want filter complete.cases()
only for the particular variable it test for each time. Eg: if it is doing the test for variable1
it should check the complete.cases()
for only variable1
. Can someone please help me how to accomplish it? Following is the code I am using now.
ANSWER
Answered 2022-Feb-01 at 09:39You can use !is.na(variable)
to drop rows with NA
values only for specific variable.

QUESTION
I have a webpage that displays some products. This webpage has around 50 products, and when i click on load more, more products are displayed. I want to extract information for all these. I have written a code for same. The problem however is, that the program proceeds with retrieving information without waiting for the button to be clicked. I have tried changing the time.sleep values to very high values, but no avail. Is there some other expression i could include to make the rest of the code wait till the button is clicked?

QUESTION
I have a page, and I have 3 radio buttons on it. I want my code to consecutively click each of these buttons, and as they are clicked, a value (mpn) is displayed, I want to obtain this value. I am able to write the code for a single radio button, but I dont understand how i can create a loop so that only value of this button changes (value={1,2,3})

You were a small step from the correct solution! In particular, the find_element_by_xpath()
function returns a single element, but the similar function find_elements_by_xpath()
(mind the plural) returns an iterable list, which you can use to implement a for loop.

QUESTION
I have a link, and within that link, I have some products. Within each of these products, there is a table of specifications. The table is such that first column should be the header, and second column the data corresponding to it. The first column for each of these tables is different, with some overlapping categories. I want to get one big table that has all these categories, and in rows, the different products. I am able to get data for one table (one product) as follows:
...ANSWER
Answered 2020-Jun-26 at 07:31Assuming that the headers are consistently the first row of each table, you just have to skip that row in every table but the first. A simple way to do that is to store the first row to process in a variable initialized to 0 and set it to 1 in the processing function. Possible code:

I'am developing a script for one of our clients, they are using some accounting apps that need to be closed on the terminal server in order to update the apps from time to time.
I've came up with a script that will ask what the user want to do and then show him the correct out put, the thing is, that my out put looks like a hashtable when, and I don't know what to do in order to group the output correctly and organize it by the process name
here is a part of the code:
$apps = Get-Process CpaPlus,ShklMnNT,HonProj,hisMain,hazharon -IncludeUserName
$apps|Group-Object ProcessName
the output looks like that:

Answered 2020-Jun-10 at 15:04If you want to group on both ProcessName

QUESTION
I want to connect an application (Oscar) to Google Fit to record my CPAP results.
Oscar is an application and not a mobile or web app, so I would have to push the data manually. It doesn't seem to be a difficult job, but I'm wondering if it's allowed. I can't see anything that forbids desktop applications or CLIs to interact with Google Fit, but I can't see anything that allows it either. The documentation only talks about websites and apps.
...ANSWER
Answered 2020-Apr-11 at 14:33There is no reason in general why a command-line application cannot write data to fit: it's ultimately all just data.
However, the fact you are trying to write data about a medical device means that you cannot use Fit. From the terms of use:
Google does not intend Google Fit to be a medical device. You may not use Google Fit in connection with any product or service that may qualify as a medical device pursuant to Section 201(h) of the Federal Food Drug & Cosmetic (FD&C) Act.

Install CPAP
You can use CPAP like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
