influx_select {influxdbr}

influx select helper

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

Sets the name of the measurement.

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.
