Plot method for visstat objects

Source: R/visstat_methods.R
plot.visstat.Rd

Replays captured plots or reports saved plot file paths from a visstat object.

Usage

# S3 method for class 'visstat'
plot(x, which = NULL, ...)

Arguments

x

An object of class "visstat", returned by visstat().

which

Integer selecting a single plot to display (1, 2, ...). If NULL (the default), all available plots are listed without being drawn.

...

Currently unused. Included for S3 method compatibility.

Value

The object x, invisibly. Called for its side effect.

Details

When called without which, the method lists all available plots (either as file paths or as indices of captured plots). When called with which, the selected plot is displayed: for file-based output the stored path is printed, for captured plots the plot is replayed via replayPlot().

Examples

# File-based output: plot() lists stored paths
anova_path <- visstat(
  npk$block,
  npk$yield,
  graphicsoutput = "png",
  plotDirectory = tempdir()
)

plot(anova_path)
#> Plot [1] stored in /tmp/RtmpTUiBDs/glm_assumptions_yield_block.png
#> Plot [2] stored in /tmp/RtmpTUiBDs/anova_yield_block.png

# Interactive output: plot() lists available plots,
# plot(obj, which = n) replays a specific one
linreg <- visstat(trees$Height, trees$Girth)
#> Warning: Statistical assumptions violated:
#> Normality of residuals violated (Shapiro-Wilk p = 0.0373 )
#> Homoscedasticity violated (Breusch-Pagan p = 0.0158 )
#> Analysis proceeded but interpret results cautiously.
#> RECOMMENDATION: Consider exploring alternatives outside visstat() such as data transformations,
#> generalised linear models, or robust regression. For a non-causal alternative
#> consider rerunning with correlation = TRUE.

plot(linreg)
#> Plot [1] captured. Use plot(obj, which = 1) to display.
#> Plot [2] captured. Use plot(obj, which = 2) to display.
plot(linreg, which = 2)
#> Warning: calling par(new=TRUE) with no plot
