Discover essential techniques to check for column existence in R data frames!
Use %in% with names() or colnames(), explore dynamic checks with exists() and within(), or identify patterns with grepl(). Experiment with these methods in your projects.
I was up late trying to figure out a stupid issue I was having with the Crowdstrike API so I didn't stream on twitch last night, hoping to do a stream tonight. I think they took a feature out my team was actually using which would allow me to contain a device and make a note that could be viewed in the dashboard.
I did the first #chess board render with my #RustLang chess engine :o I'm really happy with how it turned out. And it also shows that the white kingside castling worked xD (Assets from itch.io)
Guys, it's happening... I think I'm officially getting older.. 🫠
Gone are the nights of 24/7 #gaming parties fueled with Monster and Red Bull (though I can definitely still pound them during late night #coding binges 🤗), and have given way to regularly having my #trading app open to watch my #stock investments and snag positions throughout the day/week...
Nowadays, I somehow seem to get off on #analytics data and stock charts... 🙈🙈
👍 In R, you can easily extract specific columns from a data frame by their numerical positions. For instance, to grab the second column from a data frame df, you can use df[, 2].
🙅♂️ You can also exclude columns by using negative indexing, such as df[, -2] to exclude the second column.
Back in the days of Twitter, @platformalist did Tweet Tweet Jam, a challenge where you would submit games coded with 500 characters or under.
Now I'm here, and he's still hosting it - this year is Tweet Tweet Jam 9, and you have 6 more days to submit your 500 character games: https://itch.io/jam/tweettweetjam-9
Today I am writing on the AIC functions available in my hashtag#R hashtag#Package TidyDensity.
There are many of them, with many more on the way. Some of them are a little temperamental but not to worry it will all be addressed.
My approach is different then that of fitdistrplus which is an amazing package. I am trying to forgo the necessity of supplying a start list where it may at times be required.
I am now working on my own chess API and it’s actually pretty fun. I learned that using bitboards is apparently very efficient. So I now use 8 64bit bitboards, 2 for the color and 6 for the pieces (I thought about just using 7 because you COULD theoretically represent the colors in one bitboard, but using 2 makes it faster at the expense of an extra 64 bit, which is neglegible). Gonna continue on this in the upcoming days :3
Modern current code should run asynchronously if possible and useful. Slowly but steadily, it is being implemented in almost all popular programming languages, including WebDev.
