join_as_of: Wrapper for data.table to perform a join as of

In Beachnad/dbr: Personal R Package

Description

Given I find the syntax used by DT to be quite tedious to learn, this function abstracts the operation of performing a join as of leveraging the performance of DT.

Usage

join_as_of(left_df, right_df, on, left_time, right_time,
  direction = "forward")

Arguments

left_df	The left side of the join. Should be a data frame.
right_df	The right side of the join. Should be a data frame.
on	What column to join on.
left_time	The name of the column within left_dt to join as of.
right_time	The name of the column within right_df to join as of.
direction	Which direction to join as of. Should be 'forward', 'backward', or 'nearest'
