Description

venndir label style

Usage

venndir_label_style(
  venndir_output,
  show_labels = c("Nsc"),
  label_preset = c("none", "main inside", "main outside", "outside", "all outside",
    "concept", "meme", "items", "main items", "main count items", "custom"),
  label_style = c("basic", "box", "fill", "fill_box", "shaded", "shaded_box", "lite",
    "lite_box"),
  lite = "#FFEEAABB",
  bg = "white",
  set = c("outside", "inside", "none"),
  overlap = c("none", "inside", "outside"),
  percent = c("none", "inside", "outside"),
  count = c("inside", "outside", "ifneeded", "detect", "none"),
  signed = c("inside", "outside", "ifneeded", "detect", "none"),
  items = c("none", "inside"),
  percent_delim = "<br>",
  show_items = c("none"),
  max_items = 3000,
  inside_percent_threshold = 0,
  label_types = c("main", "signed"),

)

Arguments

show_labels	character string to describe which count labels to display, and where. The presence of each letter enables each label, and UPPERCASE places the label outside the Venn diagram, while lowercase places the label inside. The default "Ncs" displays _N_ame (outside), _c_ount (inside), and _s_igned count (inside). When overlap_type="overlap" then the signed label is hidden by default. The label types are defined below: _N_ame: "n" or "N" - the set name, by default it is displayed. _O_verlap: "o" or "O" - the overlap name, by default it is hidden, because these labels can be very long, also the overlap should be evident in the Venn diagram already. _c_ount: "c" or "C" - overlap count, independent of the sign _p_ercentage: "p" or "P" - overlap percentage, by default hidden, but available as an option _s_igned count: "s" or "S" - the signed overlap count, tabulated based upon overlap_type ("each", "concordant", "agreement", etc/) _i_tems: "i" only, by default hidden. When enabled, item labels defined by show_items are spread across the specific Venn overlap region.
label_preset	DEPRECATED in favor of show_labels.
label_style	character string indicating the style of label to display. The values ⁠"basic","none","shaded","lite","fill"⁠ style the label background fill, while presence of "box" in the string will draw a border around the label: "basic" or "none" uses no background fill, "lite" uses lite background fill, "fill" uses opaque fill with the overlap set color, "shaded" uses slightly transparent fill with overlap set color, "box" displays border around the label.
lite	character color used when label_preset contains "lite".
bg	character color used as the background color of the figure, used with outside labels to determine whether the text should be light or dark for proper visual contrast.
set, overlap, percent, count, signed, items	DEPRECATED in favor of show_labels.
percent_delim	character string used only when both count and percent labels are enabled, as a delimiter between the two labels. The default "<br>" causes a newline, so the count and percent values are on separate lines. Another suggestion is ": " which separates the two values with semicolon on one line.
show_items	character string for the item label content, used only when items are displayed.
max_items	numeric maximum number of labels permitted when items are displayed. When there are too many items, the item label is suppressed.
inside_percent_threshold	numeric size for each polygon below which labels are moved outside, for labels that would otherwise be displayed inside. Item labels are not affected by this setting. The threshold is calculated as a percent of the overall Venn diagram polygon area.
label_types	character vector with one or more label types to be affected by this function. By default "count" and "signed" labels (all labels) are affected.
extra_styles	list of two-element vectors, named by the type of label, default list(percent=c("***", "***")) will use "***" before and after each percentage label. No other label types are supported.
show_zero	logical indicating whether to display zero 0 for empty overlaps for which the overlap polygon exists. Default FALSE hides the display of zeros.
sep	character string used as delimiter between Venn set names. This value should generally not be changed.
useGrey	numeric value used by jamba::setTextContrastColor() to define an appropriate contrasting color which retains some color saturation, default 15. Use useGrey=0 would cause black or white labels with no color saturation.
verbose	logical indicating whether to print verbose output.
...	additional arguments are passed to internal functions such as make_color_contrast().

Details

This function applies a label style to venndir() output, overwriting the existing label style as necessary.

This function adjusts the label text color for contrast with make_color_contrast(), which is useful when positioning the label on top of dark or bright colors. If the label is positioned outside the sp polygons, the text is assumed to be on a white background, using argument bg.
