问题
I have tried install.packages("Rtools"), but this provides an error that states
package ‘Rtools’ is not available (for R version 3.5.1)
Given that the latest version of R is just a week old, should I wait for the R developers to catch up, or is this a bug I should report?

No, I think it's related to devtools. You can check that devtools:::version_info is lacking 3.5. You could use this as a workaround:
library(devtools)
assignInNamespace("version_info", c(devtools:::version_info, list("3.5" = list(version_min = "3.3.0", version_max = "99.99.99", path = "bin"))), "devtools")
Now your install commands for any package that needs compilation will work again, assuming you have version 3.5 of it installed from https://cran.r-project.org/bin/windows/Rtools/.
