Lazy operations

This set of S3 classes describe the action of dplyr verbs. 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.

Keywords
internal
Usage
op_base(name, src, x, vars)

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)

Details

op_vars and op_grps compute the variables and groups from a sequence of lazy operations. op_sort tracks the order of the data for use in window functions.
