Creating Excel Workbooks with multiple sheets in R

Creating Excel Workbooks with multiple sheets in R

Data Science, Recent Posts
Creating Excel Workbooks Generally, when doing anything in R I typically work with .csv files, their fast and straightforward to use. However, I find times, where I need to create a bunch of them to output and having to go and open each one individually, can be a pain for anyone. In this case, it's much better to create a workbook where each of the .csv files you would have created will now be a separate sheet. Below is a simple script I use frequently that gets the job done. Also included is the initial process of creating dummy data to outline the process. EXAMPLE CODE: Libraries used library(tidyverse) library(openxlsx) Creating example files to work with products <- c("Monitor", "Laptop", "Keyboards", "Mice") Stock <- c(20,10,25,50) Computer_Supplies <- ...

Sort

The command sort is used to sort files line by line.  Lines starting with a number go first. Lines that come next in order go alphabetical with uppercase letters appearing before lowercase ones. Use cat to create "testsort" for the example. ~/Test>cat testsort A line 1 a line 2 8 line 3 line 4 5 line 5 ~/Test>sort testsort 5 line 5 8 line 3 A line 1 a line 2 line 4 R sorts by using a random hash of keys ~/Test>sort -R testsorta line 25 line 5A line 18 line 3line 4 ~/Test>sort -R testsort5 line 5A line 1a line 2line 48 line 3

The War of Automation

Blog, Recent Posts
What happens when +90% of the jobs are not automated? No longer will we need doctors or surgeons, instead hospitals will just need a single person to decide on moral choices. More of a supervisor that really their time will be spent monitoring the machines. Kids will have no idea humans would drive trucks or even personal vehicles. They'll say "Why did you not care about safety and efficiency. Robots/Machines are better in every aspect." Side note: any movies like Terminator or iRobot will no longer be legal to watch Population Control: Concerns of overpopulation begin to be debated by the top 1%, with no longer having to work or work +40hrs a week births begin to increase. Wars are fought in the cyber world, no longer will militaries need boots on the ground as much rather than boots ...

10 Year Challenge: AI Edition

The Challenge as it is now, is to post two pictures of yourself side by side. One of the pictures is from 2008 while the other is from 2018. Seems pretty harmless at first glance, however Fortune 500 adviser and tech writer Kate O'Neill had this to say on Twitter. Me 10 years ago: probably would have played along with the profile picture aging meme going around on Facebook and Instagram Me now: ponders how all this data could be mined to train facial recognition algorithms on age progression and age recognition Kate O'Neill With the growth of data mining and facial recognition software it will be interesting to see if this has any ef...
