compare_dfs: Compare Data-Frames

In KO112/KO: Kevin O'Brien's Personal Package

Description

Compare two data-frame (like) objects. The function will compare the objects by column names, and print information about differences.

Usage

compare_dfs(
  df1,
  df2,
  printColDiffs = 1,
  tol = 1e-10,
  trim = TRUE,
  blankEqualsNA = FALSE
)

Arguments

df1	The first object inheriting from a data.frame.
df2	The second object inheriting from a data.frame.
printColDiffs	What level of messages to print regarding the differences between columns (integer scalar).
tol	The acceptable tolerance for equality between numeric columns (numeric scalar).
trim	Whether or not to trim whitespace from character columns (logical scalar).
blankEqualsNA	Whether or not blanks and considered equal to NA in character vectors (logical scalar).

Value

A list of column comparison data for each non-identical column.

Examples

# Returns an empty list, since the objects are identical
compare_dfs(mtcars, mtcars)

# Prints a message about the difference in column names
compare_dfs(mtcars, mtcars[, -1])

# Prints a message about the difference in values, & returns a tibble showing the differences
compare_dfs(mtcars, dplyr::mutate(mtcars, mpg = mpg * 2))

# Same as the above, but doesn't print the message about the differences
compare_dfs(mtcars, dplyr::mutate(mtcars, mpg = mpg * 2), printColDiffs = FALSE)
