Full join on an arbitrary number of 'data.frame' objects passed as arguments,
preserving all unique entries. Can be used to combine historical time
series data where each observation is indexed by a unique timestamp and
all periods are complete.
Usage
df_merge(...)
Value
A data.frame containing all unique entries in the objects passed as
argument.
Arguments
...
data.frame objects to combine.
Details
Can be used to join price dataframes retrieved by oanda.
The function is designed to join complete historical data. If the data to
be merged contains data with incomplete periods, all entries are
preserved rather than updated. If incomplete periods are detected within
the data, a warning is issued, and the resulting dataframe should be
manually checked in case it contains unwanted duplicates. Use
df_append for updating dataframes with new values.
