[R] Need help plotting

Tue Sep 20 19:30:37 CEST 2022

Have you done something like this first?
install.packages("chron")

After that comes

library(chron)

and the rest of your code.

"Also, IU's tech support told me yesterday that if I responded to a message that came as plain text, my response would go out as plain text.  Is that true for this response, or is it in HTML?"

Nope, HTML. You need to set your email client to send in plain text. Do an internet search on how to do this, e.g. with "How to send plain text email for <<your email client here>>".

Also see "?download.packages" for how to get packages from an R package repository (though RStudio and no doubt other IDE's have an interface through which to do this).

Cheers,
Bert
