A special type of plot where Weibull distributed data plots as a straight
line. This was also originally called Rayleigh paper. Both Rayleigh and
exponential distributions also plot as straight lines.
Usage
weiplot(data, n = 70, type = "p", xlim = NULL, ylim = c(0.01, 10),
main = "Weibull Plot", sub = NULL, ylab = "log(1/1-F(x))",
ylab2 = "F(x)", xlab = "x", percent = "False")
Arguments
data
data values from which a cumulative density function will be
estimated using ecdf(data)
n
number of points required in plot (default n = 70).
type
plot type
xlim
the minimum and maximum to be used for the x-axis
ylim
the minimum and maximum to be used for the y-axis
main
the title of the plot
sub
the sub-title of the plot
ylab
the title of the left y-axis
ylab2
the title of the right y-axis
xlab
the title of the x-axis
percent
logical; display right hand axis as percentages
Details
A Weibull plot uses log paper and has log(1/(1-F(x)) versus x,
where the data values x have an empirical cdf of F(x). The plot
margins may need to be adjusted so that the right hand axis is
visible.
