QUESTION
So i have a dataframe, df:
...ANSWER
Answered 2021-May-11 at 22:42First off, it's important to know why you're missing data, and to see if you can possibly impute rather than just drop.
If you still want to drop, you can use df = df.dropna(how='any')
.
The reason why Excel shows "N/A" as the value for missing data is because that's Excel's way of showing missing data. It doesn't mean that the value of the cell that is missing data is N/A
--that would be a string containing an N, a slash, and an A. Instead, you can try df = df[~df['Year'].isnull()]
as an alternative method for selecting non-null values.

QUESTION
In a totally custom Wordpress page, written as a PHP snippet using Woody Snippets plugin, I need to use a jQuery datepicker to select a date.
I imported the necessary files correctly, and also called and set up the datepicker correctly. Yesterday, I attached the datepicker to a hidden input field, so that when I clicked on an icon, the calendar would float in place, and everything was fine, even the localization, although I hadn't taken any measures for the localization of the calendar (importing the i18n files etc)...
Today, I had to change the page's layout a bit, so I had to make the calendar show from the beginning (inline). According to the demo page, in order to put the datepicker inline, all you have to do is attach it to a div instead of an input field.
The datepicker indeed turned into an inline element, but the localization went away... The initial language is English, until I interact in any way with the calendar (go back or forth a month, or pick a date, etc). Once I do that, the localization turns into my site's language!
What's more crazy is that this situation continued even after I specifically imported and set up the localization.
...ANSWER
Answered 2021-Apr-04 at 16:01This must have been a conflict in my site. TBH, I wasn't able to spot the conflict, but I was able to circumvent it by setting the necessary lang strings just before datepicker's initiation like so:

. strsplit
itself returns a list which you can turn into an atomic vector with unlist
