ggslice {mulgar}

Generate an axis-parallel slice display

Description

Following the slice definition available in tourr this function returns a ggplot2 display of a slice defined via the projection onto two of the variables. Note that because the underlying function works with any projection, the axis labels need to be set by the user.

Usage

ggslice(data, h, v1 = 1, v2 = 2, center = NULL, col = NULL)

Arguments

data

data frame containing only variables used for the display

h

slice thickness

v1

column number of variable mapped to x-axis

v2

column number of variable mapped to y-axis

center

center point vector used for anchoring the slice, if NULL the mean of the data is used

col

grouping vector mapped to color in the display

Value

ggplot2 object showing the sliced data
