all_equal: Flexible equality comparison for data frames

In hadley/dplyr: A Grammar of Data Manipulation

Flexible equality comparison for data frames

Description

all_equal() allows you to compare data frames, optionally ignoring row and column names. It is deprecated as of dplyr 1.1.0, because it makes it too easy to ignore important differences.

Usage

all_equal(
  target,
  current,
  ignore_col_order = TRUE,
  ignore_row_order = TRUE,
  convert = FALSE,
  ...
)

Arguments

target, current	Two data frames to compare.
ignore_col_order	Should order of columns be ignored?
ignore_row_order	Should order of rows be ignored?
convert	Should similar classes be converted? Currently this will convert factor to character and integer to double.
...	Ignored. Needed for compatibility with all.equal().

Value

TRUE if equal, otherwise a character vector describing the reasons why they're not equal. Use isTRUE() if using the result in an if expression.

Examples

scramble <- function(x) x[sample(nrow(x)), sample(ncol(x))]

# `all_equal()` ignored row and column ordering by default,
# but we now feel that that makes it too easy to make mistakes
mtcars2 <- scramble(mtcars)
all_equal(mtcars, mtcars2)

# Instead, be explicit about the row and column ordering
all.equal(
  mtcars,
  mtcars2[rownames(mtcars), names(mtcars)]
)
