PoweR (version 1.0.7)

graph: p-value plot, p-value discrepancy plot and size-power curves.

Description

This function draws a \(p\)-value plot, a \(p\)-value discrepancy plot or a size-power curves plot.

Usage

graph(matrix.pval, xi = c(seq(0.001, 0.009, by = 0.001),
      seq(0.01, 0.985, by = 0.005), seq(0.99, 0.999, by = 0.001)),
      type = c("pvalue.plot", "pvalue.discrepancy", "size.power"),
      center = FALSE, scale = FALSE)

Arguments

matrix.pval

a matrix of \(p\)-values as returned by function many.pval.

xi

a vector of values at which to compute the empirical distribution of the \(p\)-values.

type

character. Indicate the type of plot desired.

center

Logical. Should we center the data generated

scale

Logical. Should we center the data generated

Examples

# NOT RUN {
stind <- c(43,44,42)   # Indices of test statistics.
alter <-list(stat43=3,stat44=3,stat42=3) # Type for each test.
# Several p-values computed under the null.
# You can increase the values of M and N for better results.
matrix.pval <- many.pval(stat.indices=stind,law.index=1,
