Reflection Questions

How was the R install process? Slightly difficult but I got the hang of it eventually. The videos weren’t as helpful as I’d hoped because they only worked if you didn’t have an initial one drive account. Otherwise, everything went smoothly for me!

How was the course folder organization process I think the organization process was very easy for me and pretty straightforward, but I also had most of it set up before this so there wasn’t as much for me to do during that part of the process.

Installing new packages

#install.packages("psych")
#install.packages("psychTools")

Calling packages

library(psych)
library(psychTools)

Call in sample data “epi.bfi” from the psych tools psychTools package

data("epi.bfi")
summary(epi.bfi)

Run the histogram and mean functions on “bdi” variable

hist(epi.bfi$bdi)

mean(epi.bfi$bdi)
## [1] 6.779221

This is the end of the Firt R lab – we did it!
