lazy_ops: Lazy operations
In sctyner/dplyr050: A Grammar of Data Manipulation

Description Usage Details

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.

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)

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.
