  extended = TRUE
)

db	a data.frame with ordered columns
operator	comparison operator
row_id	an optional row id
extended	logical if TRUE

Value

a list of checks with values or (if extended = FALSE) a compact data.frame with non-passed checks and variable mentioning

Examples

(data <- data.frame(id = letters[1:4],  x = c(1,2,3,4), y = c(0,1,3,NA), z = rep(0, 4)))
compare_columns(data[, -1], operator= '<')
compare_columns(data[, -1], operator= '>')
compare_columns(data[, -1], operator= '<', row_id = data$id)
