The ls() function with modification to avoid listing hidden
pbd objects.
ls(
name,
pos = -1L,
envir = as.environment(pos),
all.names = FALSE,
pattern,
sorted = TRUE
)as the original base::ls().
As the original base::ls() except when all.names is TRUE
and envir is .GlobalEnv, hidden pbd objects such as
.pbd_env and .pbdenv will not be returned.
As the original base::ls(), it returns the names of the objects.
