)

Arguments

modelCI

An object created by buildModelCI

title

The name of the plot, if NULL then no name is given

xlab

The x label

ylab

The y label

lwdInner

The thickness of the inner confidence interval

lwdOuter

The thickness of the outer confidence interval

pointSize

Size of coefficient point

color

The color of the points and lines

cex

The text size multiplier, currently not used

textAngle

The angle for the coefficient labels, 0 is horizontal

numberAngle

The angle for the value labels, 0 is horizontal

shape

The shape of the points

innerType

The line type of the inner confidence interval

outerType

The line type of the outer confidence interval

outerCI

How wide the outer confidence interval should be, normally 2 standard deviations. If 0, then there will be no outer confidence interval.

innerCI

How wide the inner confidence interval should be, normally 1 standard deviation. If 0, then there will be no inner confidence interval.

multi

logical; If this is for multiplot then leave the colors as determined by the legend, if FALSE then make all colors the same

zeroColor

The color of the line indicating 0

zeroLWD

The thickness of the 0 line

zeroType

The type of 0 line, 0 will mean no line

numeric

logical; If true and factors has exactly one value, then it is displayed in a horizontal graph with continuous confidence bounds.

fillColor

The color of the confidence bounds for a numeric factor

alpha

The transparency level of the numeric factor's confidence bound

horizontal

logical; If the plot should be displayed horizontally

facet

logical; If the coefficients should be faceted by the variables, numeric coefficients (including the intercept) will be one facet

scales

The way the axes should be treated in a faceted plot. Can be c("fixed", "free", "free_x", "free_y")

value

Name of variable for value metric

coefficient

Name of variable for coefficient names

errorHeight

Height of error bars

dodgeHeight

Amount of vertical dodging

interactive

If TRUE an interactive plot is generated instead of [ggplot2]

linetype

The linetype of the error bars

Value

a ggplot graph object
