            Is there an R function to help turn State abbreviations into full names? Or Vice Versa?
            Asked 2022-Apr-18 at 03:52

            I have two large-ish data frames I am trying to append...

            In df1, I have state codes, county codes, state names (Alabama, Alaska, etc.), county names, and years from 2010:2020.

            In df2, I have county names, state abbreviations (AL, AK), and data for the year 2010 (which I am trying to merge into df1. The issue lies in that without specifying the state name and simply merging df1 and df2, some of the data which I am trying to get into df1 is duplicated due to there being some counties with the same name...hence, I am trying to also join by state to prevent this, but I have state abbreviations, and state names.

            Is there any way in which I can make either the state names in df1 abbreviations, or the state names in df2 full names? Please let me know! Thank you for the help.

            Edit: dput(df2)

            Here's one way you could turn state abbreviations into state names using R's built in state vectors:

            Any ideas why I get a connection error when trying to run a redis command from one container to another? I'm trying to run an old python 2.7 lambda locally in order to test before upgrading to 3.8.10 I'm running a script that builds and links redisdb container with my_app container:

            Your python app is trying to talk to Redis on localhost but the Redis container is on a different localhost.

            You should be able to use the link configured in the docker run ... command, i.e redisdb, for the host option.



            Moment JS has 100 or so more timezones compared to PHP, bug? How do I get them in PHP
            Asked 2021-Apr-04 at 17:49

            I'm using Moment JS, and have just recently outputted the timezones listed using this.$ in my Nuxt JS project. However, the timezones that my server has inside of the timezone_identifiers_list function in PHP seems to be about 100 or so less, and weirdly, it seems that some important ones are either missing from PHP, or not meant to be in Moment, such as:


            Why would PHP not contain these missing timezones from Moment?

            I'll attach a screenshot of the ones that appear to be outputted from Moment that aren't in PHP, wondering how I can get these timezones into that PHP list?

            I've outputted the list of timezones from PHP into a string, because I'm going to have to compare the moment ones then and set a default if my timezone guess logic picks one that doesn't exist since I have a Laravel validation rule for timezone.

            There's a thing called tz, zoneinfo, or the Olson database. It's maintained by the Internet Assigned Numbers Authority

            It names zones in Continent/City or sometimes Continent/State/City format, like Asia/Kolkata or America/Indiana/Knox. Each named zone contains rules for converting to and from UTC time to local time, including the correct handling of summer time.

            The database contains the temporopolitical history of time zone and summer time changeovers for the city (and surrounding regions). So, if the government of, say, Knox Indiana USA, changes the summer time rules next year, their entry gets updated in a maintenance release of the database.

            If Spain decides to repudiate its Franco-era decision to use the same time zone as 'Europe/Berlin', and move to the same zone as 'Europe/Lisbon', the updated zoneinfo data for 'Europe/Madrid' will reflect that change on its effective date. Updates to UNIX-based operating systems like Linux and MacOS include the most recent zoneinfo data.

            php uses zoneinfo. So does MySql. moment.js adds synonyms to it. If somebody in Knox sets their time zone to moment's synonym 'US/Central' and the city council the changes the rules, they won't follow the change.

            So, please consider using php's list in your application, because it's proven so far to be future-proof.

            How to pass columns in two data frames to Haversine Function?
            Asked 2021-Feb-21 at 05:06

            I'm new to the lat & long stuff. I found a Haversine Function that looks interesting. I have two data frames that I am trying to feed into the function, but I'm getting an error.

            Here's the function.

            It's because you are passing the series data, instead, you need to pass single values..



            Trying to compare two data frames based on difference between latitude and longitude in each data frame
            Asked 2021-Feb-19 at 22:35

            I am trying to compare lat & long coordinates in two data frames. If the difference in latitude_fuze is < .01 latitude_air and if the difference in longitude_fuze is < .01 longitude_air, then I want to update the field df_result['Type'] to read 'Airport'. Basically, I have a DF with airport lat & long coordinates, and if these coordinates are very similar to the lat & long coordinates that I have in my business DF, I want to add a flag to the business DF to indicate that this is an airport.

            Here is the code that I am testing.

            I've been using Pandas to convert a .CSV file into a format that's readable on another system and I'm close to finishing it, but I just can't get it to work with timezones that are negative (UTC-1, -2 etc)

            How can I extract elements from a list of lists based on element type instead of name or position?
            Asked 2020-Aug-18 at 14:08

            I have a list of lists (of lists of's lists all the way down) called geos with geolocation information for U.S. cities returned by the Google Maps API using the geocode() function in ggmaps (see dput at the bottom of this question for a representative sample of data on 10 cities).

            I would now like to use bits of this list to populate a data frame with one row per location, i.e., per element of the vector of locations used in the API query. For argument's sake, let's say I wanted the resulting data frame to include columns for locality, administrative_area_level_2 (county), and administrative_area_level_1 (state), using long names for the first two and the short name for the last. Here's how the desired result would look.
