QUESTION
I have a data set that includes meteorite landings. It is really cool to see, but it only has coordinates for location data: latitude, longitude, and another variable that includes both of those in a coordinate format.
Is there a way I can convert these into a new variable for the country in which they are located? I have heard of geonames, but that only does one at a time, and I am looking at over 30,000 locations (haha). I could also potentially use a function to go through it, but I've heard it will run into errors with points in the ocean, which there are some here.
My goal here is to create a cartogram. If I can do that with the coordinates instead of making the country names for the entire world, please let me know.
Any help with this is appreciated.
The data set can be downloaded at https://www.kaggle.com/datasets/nasa/meteorite-landings, and the code can be filtered with this code:

Answered 2022-Apr-15 at 20:05Although it's possible to do this with several different online APIs, the free reverse geocoding APIs tend to handle only one point at a time, and a large data frame like yours could take hours to work through.
I would be tempted to use an R package with country info and map the points to countries using sf
or sp
.
The following function returns a vector of country names given a vector of latitudes and a vector of longitudes:

QUESTION
[Question posted by a user on YugabyteDB Community Slack]
A question that came in my recent large-scale tests, say that I have a multi-regional cluster and I lose a complete region, with volumes and everything, say the thing was obliterated by a meteorite.
Is there any way to tell the complete system hey, this region is never coming back, please discard it and continue working
?
ANSWER
Answered 2021-Oct-15 at 13:29This is not available with a single command. Say it's a 3 region cluster. You can't "normally" continue working because you're down to 2 regions. The cluster will be online, but since all those nodes are lost you'll have to add new nodes to the region to have 3 available regions again.
This can be done by discarding all nodes in the down region one by one and adding new nodes to the same region.
For a step by step guide check this doc: https://docs.yugabyte.com/latest/manage/change-cluster-config/
QUESTION
Edit: I'm very stupid - forgot that I declared keys twice. Declaring the same key twice will not throw an error; it will overwrite the previously defined key.
I create a dict of various objects... Everytime I run the script (I have checked that the file updating), the second index of the first few objects in the dict are changed. I am not changing them anywhere in my code. I threw the dict and print into a separate python file with nothing else and I still got the same results.
...ANSWER
Answered 2021-Sep-19 at 03:51You have duplicate keys in the dict defintion. In this case, the later values will override the earlier ones. For example:

This is the data that I need:
I already imported the table into R:
...ANSWER
Answered 2021-Mar-04 at 03:06You could grab the table without isotopes, then mimic the post request the page does if you decide to go with isotopes; then left-join the two on Name
column. You will get more rows back than were in left table (no isotopes) because there are multiple Change values
, but this matches with what you see in the method of viewing isotopes you describe, where there are comma separated lists of values against isotopes, within plots, rather than split out by rows.
I go for a more selective css selector to target the specific table of interest initially, rather than indexing into lists.
I use write_excel_csv
to preserve the character encoding of headers on write out (an idea I got from @stefan).
You can remove columns you don't want in output from joint_table
before writing out (subset/select etc).

QUESTION
Today, I just created a typing meteorite project. I thought it would be great to simply call system("py -3.8 wait.py 0.1");
in C++ to wait for 0.1 seconds. It was successful in normal execution in visual studio code, but when I execute the compiled .exe file, it repeatedly shows that the file wait.py
does not exist, which is false in my scenario.
Any help regarding the problem will be appreciated.
...ANSWER
Answered 2021-Jan-31 at 00:24Use a absolute path for call wait.py !
For example:
system("py -3.8 C:\Users\wait.py 0.1");
QUESTION
I am getting invalid syntax (, line 15) pylint(syntax-error) [15,6] which is preventing me from making migrations. Was working before I added a few fields that one was working before.
It had previously worked.
I added the model class choices using named groups to group the meteorites instead of inherited classes which people say causes issues from what I read. Could find anything in it that could cause it but still a possibility.
I have tried deleting and reformatting it to see if the indentation was off nothing working. This usually fixes issues for me.
i also tried this stackoverflow result Adding ImageField to model causes exception in django
But I had pillow already installed and the unicode part did not make a difference.
I also checked to see if [my parenthesis are balanced][1] which I believe they are but was a stackoverflow result. . I added the default to everything so i can makemigrations last time this worked and i made migrations and added a example.

QUESTION
I cannot get the map to react with the sliders. THe data was from https://www.kaggle.com/nasa/meteorite-landings/data# when i move the sliders the map "refreshes" like it resets itself as if something were going to change but all of the data points show up on the graph. any help would be appreciated.
...ANSWER
Answered 2020-May-01 at 19:13The issue here is that although you correctly used the reactive value filtered()
in your leafletProxy
call, you use the non-reactive version of ReMeteor
in your addMarkers
call.
