xpnorm

Augmented versions of pnorm and qnorm

Description

These functions behave similarly to the functions with the initial x removed from their names but add more verbose output and graphics.

Usage

xpnorm(
  q,
  mean = 0,
  sd = 1,
  plot = TRUE,
  verbose = TRUE,
  invisible = FALSE,
  digits = 4,
  lower.tail = TRUE,
  log.p = FALSE,
  xlim = mean + c(-4, 4) * sd,
  ylim = c(0, 1.4 * dnorm(mean, mean, sd)),
  manipulate = FALSE,
  ...,
  return = c("value", "plot")
)

xqnorm(
  p,
  mean = 0,
  sd = 1,
  plot = TRUE,
  verbose = TRUE,
  digits = getOption("digits"),
  lower.tail = TRUE,
  log.p = FALSE,
  xlim,
  ylim,
  invisible = FALSE,
  ...,
  return = c("value", "plot"),
  pattern = c("stripes", "rings")
)

xcnorm(
  p,
  mean = 0,
  sd = 1,
  plot = TRUE,
  verbose = TRUE,
  digits = getOption("digits"),
  lower.tail = TRUE,
  log.p = FALSE,
  xlim,
  ylim,
  invisible = FALSE,
  ...,
  return = c("value", "plot"),
  pattern = "rings"
)

Arguments

`q`	quantile
`mean, sd`	parameters of normal distribution.
`plot`	logical. If TRUE, show an illustrative plot.
`verbose`	logical. If TRUE, display verbose output.
`invisible`	logical. If TRUE, return value invisibly.
`digits`	number of digits to display in output.
`lower.tail`	logical. If FALSE, use upper tail probabilities.
`log.p`	logical. If TRUE, uses the log of probabilities.
`xlim, ylim`	limits for plotting.
`manipulate`	logical. If TRUE and in RStudio, then sliders are added for interactivity.
`...`	additional arguments.
`return`	If `"plot"`, return a plot. If `"values"`, return a vector of numerical values.
`p`	probability
`pattern`	One of `"stripes"` or `"rings"`. In the latter case, pairs of regions (from inside to outside) are grouped together for coloring and probability calculation.

Examples

xpnorm(650, 500, 100)
xqnorm(.75, 500, 100)
xpnorm(-3:3, return = "plot", system = "gg") %>% 
  gf_labs(title = "My Plot", x = "") %>% 
  gf_theme(theme_bw())

## Not run: 
if (rstudio_is_available() & require(manipulate)) {
  manipulate(xpnorm(score, 500, 100, verbose = verbose),
    score = slider(200, 800),
	   verbose = checkbox(TRUE, label = "Verbose Output")
  )
}

## End(Not run)
