plotWbDir: Plot Weibull fit per direction sector

Description

Plots the fitted Weibull distribution per direction sector from a weibull object.

Usage

plotWbDir(wb, show.ak=FALSE, ...)
plwbd(wb, show.ak=FALSE, ...)

Arguments

wb

Weibull object created by weibull.

show.ak

If TRUE, the Weibull parameters A and k are added to the legend.

...

Optional graphical parameters, see below for details.

Optional graphical parameters

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

• bty: Type of box to be drawn around the plot region. Allowed values are"o"(the default),"l","7","c","u", or"]". The resulting box resembles the corresponding upper case letter. A value of"n"suppresses the box.
• bty.leg: Type of box to be drawn around the legend. Allowed values are"n"(no box, the default) and"o".
• cex: Amount by which text on the plot should be scaled relative to the default (which is1), as numeric. To be used for scaling of all texts at once.
• cex.axis: Amount by which axis annotations should be scaled, as numeric value.
• cex.lab: Amount by which axis labels should be scaled, as numeric value.
• cex.leg: Amount by which legend text should be scaled, as numeric value.
• col: Vector of colours for the sectoral distributions, with the length of sector number + 1, where the last colour is used for the general profile.
• col.axis: Colour to be used for axis annotations -- default is"black".
• col.box: Colour to be used for the box around the plot region (ifbty) -- default is"black".
• col.lab: Colour to be used for axis labels -- default is"black".
• col.leg: Colour to be used for legend text -- default is"black".
• col.ticks: Colours for the axis line and the tick marks respectively -- default is"black".
• las: Style of axis labels. One of0(always parallel to the axis, default),1(always horizontal),2(always perpendicular to the axis),3(always vertical).
• lty: Vector of line types, assigned likecol. Seeparfor usage.
• lwd: Vector of line widths, assigned likecol. Seeparfor usage.
• mar: A numerical vector of the form c(bottom, left, top, right) which gives the number of lines of margin to be specified on the four sides of the plot -- default isc(4.5, 4.5, 1, 1).
• mgp: A numerical vector of the form c(label, annotation, line), which gives the margin line for the axis label, axis annotation and axis line. The default isc(2.5, 0.7, 0).
• pos.leg: Position of legend -- one of"bottomright","bottom","bottomleft","left","topleft","top","topright","right"or"center". UseNULLto hide the legend.
• xlab: Alternative label for the x axis.
• ylab: Alternative label for the y axis.
• xlim: Numeric vector of the x limits of the plot.
• ylim: Numeric vector of the y limits.
• x.intersp: Horizontal interspacing factor for legend text, as numeric -- default is0.4.
• y.intersp: Vertical line distance for legend text, as numeric -- default is0.8.
