Optional graphical parameters

The following graphical parameters can optionally be added to customize the plot:

• col: Colour, used to fill the bars.
• border: Colour, used for the border around the bars.
• line: Colour, used for the Weibull fit line.
• lty: Line type of the Weibull fit line -- seeparfor available line types.
• lwd: Line width for the Weibull fit line -- seeparfor usage.
• cex: Numeric value, giving the amount by which text on the plot should be scaled relative to the default (which is 1).

neubuerg <- clean(neubuerg)

# calculate Weibull parameters
neubuerg.wb <- weibull(neubuerg, 1)

# plot
plotWeibull(neubuerg.wb)

# show parameters in legend
plotWeibull(neubuerg.wb, show.ak=TRUE)

# customize bars
