library(qgis)

[florisvdh]

Hi Jan,
I saw in README 'The package is not meant to be load directly as this would significant number of functions (<900).'. Actually I don't think that's a problem on modern systems. Loading time is still mainly taken by loading qgisprocess in the background.

So I think it's no problem to do library(qgis):

> system.time(library(qgisprocess))
Attempting to load the cache ... Success!
QGIS version: 3.28.3-Firenze
Having access to 785 algorithms from 9 QGIS processing providers.
Run `qgis_configure(use_cached_data = TRUE)` to reload cache and get more details.
   user  system elapsed

# New R session

> system.time(library(qgis))
Attempting to load the cache ... Success!
   user  system elapsed 
  2.218   0.267   2.675 
> ?qgis_ruggednessindex
starting httpd help server ... done

Also the extra occupied memory can be ignored relative to qgisprocess:

> lobstr::mem_used()
31.09 MB

Ok, thanks for the tests. I just though that the loading the package will take more resources with respect to its size ;-) I will remove the text from the readme.
