lazy_ops {dbplyr} | R Documentation |
Lazy operations
Description
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.
Usage
lazy_base_query(x, vars, class = character(), ...)
op_grps(op)
op_vars(op)
op_sort(op)
op_frame(op)
Details
op_vars()
and op_grps()
compute the variables and groups from
a sequence of lazy operations. op_sort()
and op_frame()
tracks the
order and frame for use in window functions.
