| dotplot {base} | R Documentation |
Draw a Cleveland dot plot.
dotplot(x, labels = NULL, groups = NULL, gdata = NULL, cex = par("cex"),
pch = 21, gpch = 21, bg = par("bg"), color = par("fg"),
gcolor = par("fg"), lcolor = "gray", ...)
x |
either a vector or matrix of numeric values (NAs are
allowed). If x is a matrix the overall plot consists of
juxtaposed dotplots for each row. |
labels |
a vector of labels for each point.
For vectors the default is to use names(x) and for
matrices the row labels dimnames(x)[[1]]. |
groups |
an optional factor indicating how the
elements of x are grouped.
If x is a matrix, groups will default to the columns
of x. |
gdata |
data values for the groups. This is typically a summary such as the median or mean of each group. |
cex |
the character size to be used. Setting cex
to a value smaller than one can be a useful way of avoiding label
overlap. |
pch |
the plotting character or symbol to be used. |
gpch |
the plotting character or symbol to be usea for group values. |
bg |
the background color to be used. |
color |
the color to be used for points an labels. |
gcolor |
the color to be used for group labels and values. |
lcolor |
the color to be used for the horizontal lines. |
... |
graphical parameters can also be specified as arguments. |
This function is invoked for its side effect, which is to produce two variants of dotplots as described in Cleveland (1985).
Dot plots are a reasonable substitute for bar plots.
