legends {vcd} | R Documentation |
These functions generate legend functions for residual-based shadings.
legend_resbased(fontsize = 12, x = unit(1, "lines"), y = unit(0.1,"npc"), height = unit(0.8, "npc"), width = unit(0.7, "lines"), digits = 3, check_overlap = TRUE, text = NULL, steps = 200, ticks = 10, pvalue = TRUE) legend_fixed(fontsize = 12, x = unit(1, "lines"), y = unit(0.2, "npc"), height = unit(0.8, "npc"), width = unit(1.5, "lines"), digits = 3, check_overlap = TRUE, text = NULL)
fontsize |
fontsize of title and p-value text. |
x, y |
objects of class "unit" indicating the coordinates
of the title. |
height, width |
object of class "unit" indicating the
height/width of the legend. |
digits |
number of digits for the scale labels. |
check_overlap |
logical indicating whether overlap of scale labels should be inhibited or not. |
text |
character string indicating the title of the legend. |
steps |
granularity of the color gradient. |
ticks |
number of scale ticks. |
pvalue |
logical indicating whether the p-value should be visualized under the scale or not. |
These functions generate legend functions for residual-based shadings,
visualizing deviations from expected values of an hypothesized
independence model. Therefore, the legend uses a supplied shading
function to visualize the color gradient for the residuals range. For
more details on the shading functions and their return values, see
shadings
.
A function with arguments:
residuals |
residuals from the fitted independence model to be visualized. |
shading |
shading function computing colors from residuals (see details). |
autotext |
character vector indicating the title to be used when
no text argument is specified. Allows strucplot to generate
sensible defaults depending on the residuals type. |
