Description Usage Arguments

View source: R/gplots.R

Description

qqnorm is a generic function the default method of which produces a normal QQ plot of the values in y. qqline adds a line to a “theoretical”, by default normal, quantile-quantile plot which passes through the probs quantiles, by default the first and third quartiles.

qqplot produces a QQ plot of two datasets.

Graphical parameters may be given as arguments to gqqnorm, gqqplot and qqline.

gqqnorm(y, ...)

## Default S3 method:
gqqnorm(y, ylim, main = "Normal Q-Q Plot",
  xlab = "Theoretical Quantiles", ylab = "Sample Quantiles",
  plot.it = TRUE, datax = FALSE, grid = TRUE, col.grid = "grey90",
  col.acc = "white", ...)

gqqplot(x, y, plot.it = TRUE, xlab = deparse(substitute(x)),
  ylab = deparse(substitute(y)), ..., grid = TRUE, col.grid = "grey90",
  col.acc = "white")

Arguments

y

The second or only data sample.

ylim

graphical parameters.

main

plot labels. The xlab and ylab refer to the y and x axes respectively if datax = TRUE.

xlab

plot labels. The xlab and ylab refer to the y and x axes respectively if datax = TRUE.

ylab

plot labels. The xlab and ylab refer to the y and x axes respectively if datax = TRUE.

plot.it

logical. Should the result be plotted?

datax

logical. Should data values be on the x-axis?

grid

logical; if TRUE, a background grid will be drawn

col.grid

grid color

col.acc

grid accent color

x

The first sample for qqplot.
