Title: | Area-Proportional Euler and Venn Diagrams with Ellipses |
---|---|
Description: | Generate area-proportional Euler diagrams using numerical optimization. An Euler diagram is a generalization of a Venn diagram, relaxing the criterion that all interactions need to be represented. Diagrams may be fit with ellipses and circles via a wide range of inputs and can be visualized in numerous ways. |

euler
objectsThis is a diagnostic tool for evaluating the fit from a call
to euler()
visually. A color key is provided by default, which
represents the chosen error metric so that one can easily detect
which areas in the diagram to be skeptical about.
error_plot( x, type = c("regionError", "residuals"), quantities = TRUE, pal = NULL, ... )

Notice that this function is purely provided for diagnostic reasons
and does not come with the same kind of customization that
plot.euler()
provides: the color legend can only be customized
in regards to its color palette and another key (instead of labels)
is completely turned off.
Returns an object of class eulergram
, which will be
plotted on the device in the same manner as objects from
plot.euler()
. See plot.eulergram()
for details.

Fit Euler diagrams (a generalization of Venn diagrams) using numerical optimization to find exact or approximate solutions to a specification of set relationships. The shape of the diagram may be a circle or an ellipse.

... |
arguments passed down to other methods |
input |
type of input: disjoint identities
( |

geometric shape used in the diagram |
loss |
type of loss to minimize over. If |
loss_aggregator |
how the final loss is computed. |
control |

factor_names |

If the input is a matrix or data frame and argument by
is specified,
the function returns a list of euler diagrams.
The function minimizes the residual sums of squares,
by default, where the size of the ith disjoint subset, and
the corresponding area in the diagram, that is, the unique
contribution to the total area from this overlap. The loss function
can, however, be controlled via the
loss
argument.
euler()
also returns stress
(from venneuler), as well as
diagError
, and regionError
from eulerAPE.
The stress statistic is computed as
where
regionError
is computed as
diagError
is simply the maximum of regionError.

Note that this data is difficult to fit using an Euler diagram, even if we use ellipses, which is clear if one chooses to study the various overlaps in the resulting diagrams.

Plot diagrams fit with euler()
and venn()
using grid::Grid()
graphics.
This
function sets up all the necessary plot parameters and computes
the geometry of the diagram. plot.eulergram()
, meanwhile,
does the actual plotting of the diagram. Please see the Details section
to learn about the individual settings for each argument.

x |
an object of class |
fills |
a logical, vector, or list of graphical parameters for the fills
in the diagram. Vectors are assumed to be colors for the fills.

a logical, vector, or list of graphical parameters for the edges
in the diagram. Vectors are assumed to be colors for the edges.

text for the labels. See |

text for the quantities' labels, which by
default are the original values in the input to |

character, expression, list or something that can be
sensibly converted to a label via |

parameters to update |
The only difference between plot.euler()
and plot.venn()
is that
quantities
is set to TRUE
by default in the latter and FALSE
in
the former.
Most of the arguments to this function accept either a logical, a vector, or a list where
logical values set the attribute on or off,
vectors are shortcuts to commonly used options (see the individual parameters), and
lists enable fine-grained control, including graphical
parameters as described in grid::gpar()
and control
arguments that are specific to each argument.
The various grid::gpar()
values that are available for each argument
are:
fills | edges | labels | quantities | strips | legend | main | |
col | x | x | x | x | x | x | |
fill | x | ||||||
alpha | x | x | x | x | x | x | x |
lty | x | ||||||
lwd | x | ||||||
lex | x | ||||||
fontsize | x | x | x | x | x | ||
cex | x | x | x | x | x | ||
fontfamily | x | x | x | x | x | ||
lineheight | x | x | x | x | x | ||
font | x | x | x | x | x | ||
Defaults for these values, as well as other parameters of the plots, can
be set globally using eulerr_options()
.
If the diagram has been fit using the data.frame
or matrix
methods
and using the by
argument, the plot area will be split into panels for
each combination of the one to two factors.
For users who are looking to plot their diagram using another package, all the necessary parameters can be collected if the result of this function is assigned to a variable (rather than printed to screen).

This function fits Venn diagrams using an interface that is
almost identical to euler()
. Strictly speaking,
Venn diagrams are Euler diagrams where every intersection is visible,
regardless of whether or not it is zero. In almost every incarnation of
Venn diagrams, however, the areas in the diagram are also
non-proportional to the input; this is also the case here.
