influx_select: influx select helper

In crab1234/influxdbr-: R Interface to InfluxDB

Description

This function is a convenient wrapper for selecting data from a measurement by calling influx_query with the corresponding query.

Usage

influx_select(con, db, field_keys, rp = NULL, measurement,
  where = NULL, group_by = NULL, limit = NULL, slimit = FALSE,
  offset = NULL, order_desc = FALSE, return_xts = TRUE,
  simplifyList = FALSE)

Arguments

con	An influx_connection object (s. influx_connection).
db	Sets the target database for the query.
field_keys	Specifies the fields to be selected.
rp	The name of the retention policy.
measurement	Character vector containing name(s) of the measurement(s).
where	Apply filter on tag key values.
group_by	The group_by clause in InfluxDB is used not only for grouping by given values, but also for grouping by given time buckets.
limit	Limits the number of the n oldest points to be returned.
slimit	logical. Sets limiting procedure (slimit vs. limit).
offset	Offsets the returned points by the value provided.
order_desc	logical. Change sort order to descending.
return_xts	logical. Sets the return type. If set to TRUE, a list of xts objects is returned, FALSE gives list of tibbles.
simplifyList	logical. If only one series is returned, the result can be flatten to directly get either a tibble or an xts object (instead of a list) (default is FALSE).

Value

A list of xts or tibbles. Empty query results yield to NULL.
