dplyr (version 0.7.1)

all_equal: Flexible equality comparison for data frames

Description

You can use all_equal() with any data frame, and dplyr also provides tbl_df methods for all.equal().

Usage

all_equal(target, current, ignore_col_order = TRUE, ignore_row_order = TRUE,
  convert = FALSE, ...)
# S3 method for tbl_df
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

# NOT RUN {
scramble <- function(x) x[sample(nrow(x)), sample(ncol(x))]

# By default, ordering of rows and columns ignored
all_equal(mtcars, scramble(mtcars))

# But those can be overriden if desired
all_equal(mtcars, scramble(mtcars), ignore_col_order = FALSE)
all_equal(mtcars, scramble(mtcars), ignore_row_order = FALSE)

# By default all_equal is sensitive to variable differences
df1 <- data.frame(x = "a")
df2 <- data.frame(x = factor("a"))
all_equal(df1, df2)
# But you can request dplyr convert similar types
all_equal(df1, df2, convert = TRUE)
# }
