These are currently used for SQL sources to separate the description of operations in R from their computation in SQL. This API is very new so is likely to evolve in the future. </p> <h3>Usage</h3> <pre> op_base(x, vars, class = character()) op_single(name, x, dots = list(), args = list()) add_op_single(name, .data, dots = list(), args = list()) op_double(name, x, y, args = list()) op_grps(op) op_vars(op) op_sort(op) op_frame(op) </pre> <h3>Details</h3> <p><code>op_vars()</code> and <code>op_grps()</code> compute the variables and groups from a sequence of lazy operations. <code>op_sort()</code> and <code>op_frame()</code> tracks the order and frame for use in window functions. </p> <hr /><div style="text-align: center;">[Package <em>dbplyr</em> version 1.4.4 <a href="00Index.html">Index</a>]</div> </body></html>
