Problems when installing R packages

-
Just a quick post to help others that may be having similar issues when trying to install R packages.

When using the install.packages command: 
install.packages("package name",lib="/my/own/R-packages/")

If you get this error message: 
Warning: Unable to access index for repository..
Package is not available for R version 3.2.1...

Here is what I did and it worked.
On the menu Options at the top of your RStudio, click on Packages, select Set CRAN Mirror. Try changing the location and it should work.

Marcus Aurelius is one of history's most celebrated figures, known not only as a Roman emperor but also as a profound philosopher.

I also noticed that some games weren’t running as smoothly as before. After doing some digging, I came across a helpful Reddit thread where others reported similar problems. One popular suggestion was to do a power cycle, which slightly improved things- but the issue still lingered. Eventually, I tried a method using Safe Mode, and to my surprise, it actually fixed the problem. I have not noticed any lagging issues since. If you're facing similar issues, this might help you too. Here’s what to do: 1. Force shut down your PS5 by holding the power button until the console turns off—don’t use the controller or go through the standard shutdown process. 2. Turn the console back on. It should boot into Safe Mode , informing you that the system wasn’t shut down properly. It will attempt to scan and fix any system errors- which, ironically, seems to...

What can be done about Food Waste?

This BBC business report shows some staggering statistics of how much food is being wasted globally. And apart from household waste, a lot of food actually never made it to our fridge. It is encouraging to see individual farmers partnering with local charities or businesses to make use of perfectly edible produce which were excluded by supermarkets due to less than perfect appearances. Charities and environmental agencies should actively pursue this type of win-win ideas. It is a brilliant policy (although it could take sometime for restaurants to get used to) to require New York City's restaurants stop sending food waste to landfills in 2015 and encourage the use of alternative operations. However, I do hope that restaurant businesses are not financially worse off because of these new requirements. If anything, corresponding environmental policies should ensure it is not more expensive or difficult in any way to send waste to these alternative operations. The project ...
