Spine plots are a special case of mosaic plots and can be seen as a generalization of stacked (or highlighted) bar plots. Analogously, spinograms are an extension of histograms.

## Default S3 method:
gspineplot(x, y = NULL, breaks = NULL, tol.ylab = 0.05,
off = NULL, ylevels = NULL, col = NULL, main = "", xlab = NULL,
ylab = NULL, xaxlabels = NULL, yaxlabels = NULL, xlim = NULL,
ylim = c(0, 1), axes = TRUE, ..., grid = TRUE, col.grid = "grey90",
col.acc = "white")
## S3 method for class 'formula'
gspineplot(formula, data = NULL, breaks = NULL,
tol.ylab = 0.05, off = NULL, ylevels = NULL, col = NULL, main = "",
xlab = NULL, ylab = NULL, xaxlabels = NULL, yaxlabels = NULL,
xlim = NULL, ylim = c(0, 1), axes = TRUE, ..., subset = NULL,
grid = TRUE, col.grid = "grey90", col.acc = "white")

x 
an object, the default method expects either a single variable (interpreted to be the explanatory variable) or a 2way table. See details. 
... 
additional arguments passed to 
y 
a 
breaks 
if the explanatory variable is numeric, this controls how
it is discretized. 
tol.ylab 
convenience tolerance parameter for yaxis annotation. If the distance between two labels drops under this threshold, they are plotted equidistantly. 
off 
vertical offset between the bars (in per cent). It is fixed to

ylevels 
a character or numeric vector specifying in which order the levels of the dependent variable should be plotted. 
col 
a vector of fill colors of the same length as 
main 
character strings for annotation 
xlab 
character strings for annotation 
ylab 
character strings for annotation 
xaxlabels 
character vectors for annotation of x and y axis.
Default to 
yaxlabels 
character vectors for annotation of x and y axis.
Default to 
xlim 
the range of x and y values with sensible defaults. 
ylim 
the range of x and y values with sensible defaults. 
axes 
logical. If 
grid 
logical; if 
col.grid 

col.acc 

formula 
a 
data 
an optional data frame. 
subset 
an optional vector specifying a subset of observations to be used for plotting.
