qqunif | R Documentation |
Produce qq-plot(s) of the given effect size and p values assuming a uniform distribution.
qqunif(x, ...)
## Default S3 method:
qqunif(x, min = 0, max = 1, ...)
## S3 method for class 'sim.power.ttest'
qqunif(x, color.line = "orange", shape = 19, size = 1,
alpha = 1, ...)
## S3 method for class 'sim.power.wtest'
qqunif(x, color.line = "orange", shape = 19, size = 1,
alpha = 1, ...)
x |
numeric vector or data (object). |
min |
single numeric, lower limit of the distribution. |
max |
single numeric, upper limit of the distribution. |
color.line |
color of the line indicating the uniform distribution. |
shape |
point shape. |
size |
point size. |
alpha |
bleding factor (default: no blending. |
... |
further arguments that may be passed through). |
The plot generates a ggplot2
object that is shown.
Missing values are handled by the ggplot2
functions.
Object of class gg
and ggplot
.
