Comparison bar chart: raw vs. the selected FDR procedures

Function type: Reporting/derived function – summarises or plots the output of another function; it does not compute any new statistic. Not exported – called internally by report = TRUE, and reachable from outside the package via plot(x, which = "comparison").

Usage

fdr_comparison_barplot(result, path = NULL)

Arguments

result

Output of fdr_correction() (must have been run on a raster, so result$rasters is populated).

path

Character or NULL. If supplied, a PNG is written there.

Value

NULL, invisibly.

Examples

# The plotting function needs an FDR result, not a complete raster trend
# analysis. Using a short p-value vector keeps the example focused and
# fast while exercising the same plotting code.
p <- c(0.001, 0.008, 0.02, 0.04, 0.3, 0.8)
fdr_result <- fdr_correction(p, report = FALSE, verbose = FALSE)

# A bar chart version of fdr_summary()'s table -- raw vs. BH vs. BKY,
# visually. Called internally by plot() on an fdr_correction()
# result -- the public entry point is:
plot(fdr_result, which = "comparison")
