Unable to install the latest version of cpp11

[priyapatel1]

I've been trying to install cpp11 so that I can use lubridate. However, I keep getting the following issue:

> install.packages('lubridate')
Installing package into ‘/usr/local/lib/R/site-library’
(as ‘lib’ is unspecified)

Restart R completely and try install.packages('cpp11') first before installing lubridate

That gives me the following error:

> install.packages('cpp11')
Installing package into ‘/usr/local/lib/R/site-library’
(as ‘lib’ is unspecified)
Warning message:
package ‘cpp11’ is not available (for R version 3.6.3)

[DavisVaughan]

cpp11 requires R >=4.0. You will have to update R to be able to use that package. Many R packages in the tidyverse now also require >=4.0, so you are likely going to have more issues if you don't update soon.

This worked, thank you!
