I am trying to create my first package that should be used with an OpenCPU
This package requires 2 things:
- to load multiple multiple objects to RAM/ Done by onLoad function.
- It depends on 3 libraries that are loaded by "Imports: data.table,
gbm, stringdist" in DESCRIPTION file. ( and lazyload is False)
My package and its dependencies are listed in preload section in the
Technically, everything works as expected, but:
When I load package first time system.time(myfunc(input)) is substantially
higher then all following timings. I don’t understand why it happens. All
dependencies are preloaded, all objects are loaded in to RAM.
On the higher scale - same (unknown to me) reason prevents package achieve
desired response delay while being used through an OpenCPU.
I can't understand why it is happening. Which way should I elaborate on the
