shiny_is_running check if shiny is running;

collapse is a parallel solution to calculate sum/mean along arrays, providing 4x speed-ups for large arrays;
make_forked_clusters enables multicore (forked clusters) in future package even in RStudio environment;
baseline_array to baseline arrays in multicore;
shift_array to shift arrays along given dimensions;
lapply_async2 uses future package, but with progress bar either in console or in shiny apps;
fastcov2 calculates covariance matrices in parallel;
rs_exec starts a new R session or job in RStudio;

eval_dirty works as base::eval, but supports quosures generated from rlang::quo;
match_calls match calls in a nested manner, and support changing the call arguments recursively;
%?<-% assigns default values to left-hand object. E.g. a %?<-% 1 assigns a to be 1 if a is NULL or does not exist;

time_delta calculates time differences and returns a number in given units;
ask_yesno, ask_or_default interactively ask for user's input either in console or in RStudio;
fastmap2 and fastqueue2 provides a wrapper of fastmap package, giving the object list-like operations;
shared_finalizer finalizes multiple elements when last element is garbage collected;
dev_create allows managing and grouping graphic devices;
print_directory_tree prints directory and containing files into tree-structures;
rs_* functions wrapping rstudioapi functions, but work without RStudio;
sexp_type2 get internal data type code;
to_datauri converts file to base64 formats.
