Join two data frames when one might not exist

Description

When accumulating data within a loop, you usually have to check whether to create a data frame or bind two data frames together. This function is a shortcut: it checks to see is df_1 exists. If so, it binds the two data frames together as usual. If not, it catches the error and returns df_2.

Usage

assign_col_join(df_1, df_2, by)

assign_row_join(df_1, df_2)

Arguments

df_1	A data frame that might exist
df_2	A data frame to join to df_1
by	If using assign_col_join, Any values to pass to full_join. If none are supplied, glptools::bind_df is used.

Functions

• assign_col_join(): Joins two data frames column-wise when one might not exist

• assign_row_join(): Joins two data frames row-wise when one might not exist
