Cannot run example

[ryw89]

Hi,

I'm having trouble running the example on my Arch Linux system.

xl_rf <- X_RF(feat = feature_train, tr = w_train, yobs = yobs_train)

yields:
/usr/include/c++/11.1.0/bits/random.tcc:2667: void std::discrete_distribution<_IntType>::param_type::_M_initialize() [with _IntType = long unsigned int]: Assertion '__sum > 0' failed.

(And then R terminates.)

Some info about my environment:

R version is: R version 4.1.2 (2021-11-01) -- "Bird Hippie"

GCC version, which owns the random.tcc file: gcc 11.1.0-3. (Version according to the Arch Linux package manager, that is.)

Thanks in advance for any help you can provide.
