spacings | R Documentation |
These functions generate spacing functions to be used with
strucplot
to obtain customized spaces between the
elements of a strucplot.
spacing_equal(sp = unit(0.3, "lines"))
spacing_dimequal(sp)
spacing_increase(start = unit(0.3, "lines"), rate = 1.5)
spacing_conditional(sp = unit(0.3, "lines"), start = unit(2, "lines"), rate = 1.8)
spacing_highlighting(start = unit(0.2, "lines"), rate = 1.5)
start |
object of class |
rate |
increase rate for spacings. |
sp |

These generating functions return a function used by
strucplot
to generate appropriate spaces between tiles of
a strucplot, using the dimnames
information of the visualized
table.
spacing_equal
allows to specify one fixed space for all
dimensions.
spacing_dimequal
allows to specify a fixed space for
each dimension.
spacing_increase
creates increasing spaces for all dimensions,
based on a starting value and an increase rate.
spacing_conditional
combines spacing_equal
and
spacing_increase
to create fixed spaces for conditioned
dimensions, and increasing spaces for conditioning dimensions.
spacing_highlighting
is essentially spacing_conditional
but with
the space of the last dimension set to 0. With a corresponding color
scheme, this gives the impression of the last class being
‘highlighted’ in the penultimate class (as, e.g., in
doubledecker
plots).
A spacing function with arguments:
d |
|
condvars |
index vector of conditioning dimensions (currently only used by
|
This function computes a list of objects of class "unit"
.
Each list element contains the spacing information for the
corresponding dimension of the table. The length of the
"unit"
objects is k-1
, k
number of levels of the
corresponding factor.
