In abarbour/stress: Tools for Working with Stresses and Focal-mechanism Inversions

# ##
# Anything needed for the functioning of the namespace should
# be handled at load/unload times by the .onLoad and .onUnload
# hooks. For example, DLLs can be loaded (unless done by a
#                                         useDynLib directive in
#                                         the NAMESPACE file)
# and initialized in .onLoad and unloaded in .onUnload.
# Use .onAttach only for actions that are needed only when the
# package becomes visible to the user (for example a start-up message)
# or need to be run after the package environment has been created.

#.onUnload <- function(libpath){
#  library.dynam.unload("stress", libpath)
#}

##
# executed after .onLoad is executed, once the namespace is visible to user
