Can anyone point me in the right direction for getting around this error? I'm new to creating packages and am currently following Hadley Wickham's guide.
http://r-pkgs.had.co.nz/description.html
To copy the comments of #zx8754, use_package is now part of the usethis package. And per the comment from #MichaelChirico, Hadley's book is updated on github, but has not yet been re-published.

as.Date(as.character(20110505), "%Y%m%d")
#[1] "2011-05-05"

Im taking an R programming class that is using the package "matplot" for a demo. I cant find "matplot" in CRAN so i'm assuming it has been replaced/deleted/changed. Is there another package that replaced it?
There is a matplot function within the graphics library. Here's an example from the documentation:
require(grDevices)
matplot((-4:5)^2, main = "Quadratic")
Also, matplot is a plotting library for PHP. Perhaps your instructor could help clarify what is expected.

I am returning to some old code where I had used the following syntax:
y[df$myvar %between% c(1,100)]
but get the error
could not find function "%between%"
This code used to work, and I have updated R in the mean time. any thoughts?
As Pascal pointed out, you should load the package data.table first:
library(data.table)
Then you'll be able to use it.
