Error in if (latest_R_version == R_version)

[jessekps]

When using create_app with usual arguments and include_R=TRUE I get the error:

Error in if (latest_R_version == R_version) { : argument is of length zero

I believe the error is in get_R.R on line 23:

latest_R_version <- readLines("https://cran.rstudio.com/bin/windows/base/", warn = F) %>%
    stringr::str_extract("[1-3]\\.[0-9]+\\.[0-9]+") %>% stats::na.omit() %>% unique()

The regular expression should start with [1-4], since R4.+ is now the current R version.

Coming to say I still have the same issue in January 2023 - but also just wondering why the regular expression could not be dynamic - why isn't the first part of the regular expression just [0-9]? That would last a good while longer...

And if you don't feel like maintaining that code, you can simply rely on rversions. It seems to be actively maintained by some well known names in the R community.

> rversions::r_release()
version                date              nickname

I am facing the same error with create_app with argument include_R = TRUE, R_version = "4.0.0"

Error in if (latest_R_version == R_version) { : 
  argument is of length zero

However when I change the 3 to 4 in the latest_R_version in trace(RInno::get_R,edit=T) and trace(RInno::code_section,edit=T)

I am still getting an error

Error in if (latest_R_version == R_version) { : 
  the condition has length > 1

How to fix this?
