Example :[{

},

inst:"KSF",
std:"12th"
}]
...ANSWER
Answered 2021-May-25 at 05:33There is no "upsert" operation for objects in arrays. If you need to make changes to that array, you will have to read the document, modify the contents of the array in memory, then update the document with the new contents of the array.
Arrays of objects usually do not work the way that people want, given their limitations on querying and updating. It's usually better to store data as documents in a nested subcollection, so they can be more easily queried and updated by the contents of their fields.
QUESTION
I have a dataframe with dates that will be changing as some column names. I want this added on to the end as a new column. I need a count of the number in each row that is NA
. I'd ideally like to do this in dplyr

as the beginning of the dataframe. Reproduction of the DF is below.
ANSWER
Answered 2021-May-21 at 20:43FYI, your reproducible example is a grouped dataframe, that's why I passed it to ungroup

QUESTION
I have a web app where I am creating a scrollable element within the page. This is a scrollable element within a scrollable page, which is difficult and irritating for those with touchscreens and smartphone devices. Instead, for smaller devices, I have implemented scrolling buttons. Instead of scrolling with a scroll bar, there will be a "up" and "down" button. How do I keep the counter from incrementing once at the bottom of the element?
Here is the code:
...ANSWER
Answered 2018-Mar-10 at 12:51You can calculate the maximum value for scrollTop with scrollHeight - clientHeight
, and then check to see if that distance has been reached each time the scrollDown button is pressed.
