tab: like tab from statar, but ONLY works for vectors
In rdisalv2/dismisc:

From https://github.com/matthieugomez/statar/ with significant modifications

1 2	tab(x, sf = TRUE, sv = FALSE, ss = 10, sort_freq = sf, sort_values = sv, suppress_small = ss)

`x`	A vector
`sf`	shorthand for sort_freq
`sv`	shorthand for sort_values
`ss`	shorthand for suppress_small
`sort_freq`	sort by frequency large to small.
`sort_values`	sort by values large to small. overrides sort_freq.
`suppress_small`	suppresses beyond this many levels for printing. only applies if sort_freq=TRUE. default 10. set to FALSE or Inf to not suppress.
