Join yspec objects together

Usage

ys_join(left, right, ...)

Arguments

left: a yspec object.
right: a yspec object.
...: more yspec objects.

Value

A single yspec object with left, right and ... all joined together.

Details

All inputs must be yspec objects. When the right spec (or specs passed under ...) is joined to the left spec, columns that exist in both left and right are removed from right before joining.

Examples


spec <- ys_help$spec()

l <- ys_select(spec, WT, BMI)
r <- ys_select(spec, TIME, TAD)
rr <- ys_select(spec, EVID, MDV, CMT, BMI)

ys_join(l, r)
