In joshmuncke/easytest: Make Testing Great Again!

Description Usage Arguments Value Examples

Performs a test that a specific column has an expected mean value. Optionally - an acceptable tolerance can be specified in standard deviations.

1	test_column_mean(df, col, mean_expected, sd_tolerance = 0)

`df`	A dataframe
`col`	The unquoted column name of the column you want to test
`mean_expected`	The expected mean value
`sd_tolerance`	The maximum number of standard deviations (+/-) tolerance

The dataframe passed to the function.

# Basic usage
test_column_mean(mtcars, qsec, 17.84875)

# Usage without a stdev tolerance means match must be exactly equal
# Often including a small tolerance is good to allow for rounding errors
mtcars %>%
test_column_mean(mpg, 20.09062, 0.01)
