ArchR complains about `nabor` package not available even if `nabor` is loaded

[JackieMium]

I am using a non-standard .libPaths() in R to keep packages relatively separate for multiple purposes, ArchR is among the ones I installed in a custom path that are not listed in .libPaths() by default. When I use ArchR I do (ArchR and nabor is installed at ~/R/x86_64-pc-linux-gnu-library/ArchR in my case):

library('ArchR', lib.loc = '~/R/x86_64-pc-linux-gnu-library/ArchR')
library('nabor', lib.loc = '~/R/x86_64-pc-linux-gnu-library/ArchR')

Both run normally without error and sessionInfo() list both as loaded.

However ArchR still complains about nabor not available. The only solution is to

.libPaths(c('~/R/x86_64-pc-linux-gnu-library/ArchR/', .libPaths()))

I believe the error comes from R/HiddenUtils.R around line 15 in the requirePackage() function:

.requirePackage <- function(x = NULL, load = TRUE, installInfo = NULL, source = NULL){
  if(x %in% rownames(installed.packages())){
    if(load){
      suppressPackageStartupMessages(require(x, character.only = TRUE))
    }else{
      return(0)
    }
  }else
....
}

Basically it is checking if the packages is listed by installed.packages(). In my case installed.packages() won't list nabor or ArchR since they are not in .libPaths(). An additionally check of return of require() inserted here should revolve this bug. If the package is already loaded or can be found by require(), then it does not matter whether its is in .libPaths() or not since it is definitely available for use. Pseudo code:

.requirePackage <- function(x = NULL, load = TRUE, installInfo = NULL, source = NULL){
    if(load & !require(x, character.only = TRUE)){
        stop('Package ', x, ' not found!')
    } else if(load & require(x, character.only = TRUE)) {
        suppressPackageStartupMessages(require(x, character.only = TRUE))
        return(0)
    }

Hi @JackieMium! Thanks for using ArchR! Please make sure that your post belongs in the Issues section. Only bugs and error reports belong in the Issues section. Usage questions and feature requests should be posted in the Discussions section, not in Issues.

If you are getting an error, it is likely due to something specific to your dataset, usage, or computational environment, all of which are extremely challenging to troubleshoot. As such, we require reproducible examples (preferably using the tutorial dataset) from users who want assistance. If you cannot reproduce your error, we will not be able to help.
Before going through the work of making a reproducible example, search the previous Issues, Discussions, function definitions, or the ArchR manual and you will likely find the answers you are looking for.
If your post does not contain a reproducible example, it is unlikely to receive a response.

In addition to a reproducible example, you must do the following things before we help you, unless your original post already contained this information:
1. If you've encountered an error, have you already searched previous Issues to make sure that this hasn't already been solved?
2. Did you post your log file? If not, add it now.
3. Remove any screenshots that contain text and instead copy and paste the text using markdown's codeblock syntax (three consecutive backticks). You can do this by editing your original post.
