R help - Jan 2022 - Error in if (fraction <= 1) { : missing value where TRUE/FALSE needed

Ivan, thanks

When I use options(error = NULL)

it says: Error during wrapup: missing value where TRUE/FALSE needed
Error: no more error handlers available (recursive errors?); invoking
'abort' restart

With traceback(), I get

4: readable_number(max_value - min_value, FALSE)
3: get_nice_ticks(lower_bound, upper_bound)

Hi

It seems that you are hiding what you really do. 

This
> options(error = NULL)
works fine without any error. So please If you want some reasonable answer
post question with data and code which is causing the error.

My wild guess is that you have some objects in your environment and you do
not know that they are used in you commands. Try to start fresh R session
and try to inspect your environment with 

ls()

A quick search of CRAN code suggests that the error originates in the
following code:

https://github.com/ModelOriented/fairmodels/blob/073a502fd2210f20f43c9c6b3deb40e520ad7de1/R/helper_functions.R#L362

Use the R debugger (see ?recover, ?debug, ?browser) to find out why
`fraction` becomes NA. It could be because lower_bound == upper_bound,
or because any of them is NA, or for some other reason. We don't know,
but you can find out.
