plot-validator-method: Plot a validator object

In validate: Data Validation Infrastructure

Plot a validator object

Description

The matrix of variables x rules is plotted, in which rules that are recognized as linear (in)equations are differently colored. The augmented matrix is returned, but can also be calculated using variables(x, as="matrix").

Usage

## S4 method for signature 'validator'
plot(
  x,
  y,
  use_blocks = TRUE,
  col = c("#b2df8a", "#a6cee3"),
  cex = 1,
  show_legend = TRUE,
  ...
)

Arguments

x	validator object with rules
y	not used
use_blocks	logical if TRUE the matrix is sorted according to the connected sub sets of variables (aka blocks).
col	character with color codes for plotting variables.
cex	size of the variables plotted.
show_legend	should a legend explaining the colors be drawn?
...	passed to image

Value

(invisible) the matrix

Examples

rules <- validator( r1 = staff.costs < total.costs
                  , r2 = turnover + other.rev == total.rev
                  , r3 = other.rev > 0
                  , r4 = total.rev > 0
                  , r5 = nace %in% c("A", "B")
                  )
plot(rules, cex=0.8, show_legend=TRUE)

data(retailers)
cf <- confront(retailers, rules)
plot(cf, main="Retailers check")
