Merge Dataframes

Description

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(...)

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.

Value

A data.frame containing all unique entries in the objects passed as argument.

Examples

data1 <- sample_ohlc_data[1:6, ]
data1
data2 <- sample_ohlc_data[4:10, ]
data2
df_merge(data1, data2)
