Curate Venn labels

Description

Curate Venn labels

Usage

curate_venn_labels(
  x,
  type = c("sign", "color"),
  curate_df = NULL,
  unicode = TRUE,
  blend_preset = "ryb",
  split = " ",
  ...
)

Arguments

x	vector of overlap labels.
type	character string where type="sign" will curate x into directional sign, and type="color" will curate x into corresponding directional color.
curate_df	data.frame or NULL with optional curation rules. The input is coerced to data.frame if necessary. The colnames are expected to include: "from" - regular expression patterns "sign" - replacement value when type="sign" "color" - replacement R color when type="color"
unicode	logical indicating whether to use Unicode characters when type="sign". Note this argument only affects the default values, it is not applied when using a custom curate_df.
blend_preset	character string passed as preset to colorjam::blend_colors() to define the color wheel used during color blending operations.
split	character string used to split each "sign" in the input string x, assumed to be space character " ". This split is required to process replacement for each "sign" value without iteratively replacing values in x which can cause re-replacement of values which is not intended.
...	additional arguments are ignored.

Details

This venndir utility function is used to convert a basic directional label such as "0 1 0 -1" suitable for display. It can output either Unicode or non-Unicode text label, or a corresponding color.

The input currently recognizes directional labels such as "0 -1 1 0" or the character labels "agreement", "concordant", "mixed". Note that zeros "0" are typically removed before calling this function.

The input vector x is split using strsplit() using whitespace delimiter by default, then each full value is matched and replaced using "from" in curate_df.

When curate_df is not supplied, default values are generated for "from" values: "1", "-1", "0", "concordant|agreement", and "mixed". Values are matched using regular expression gsub() however the full string must match, therefore from="1" will only match "1" and will not match "-1".

The curate_df must contain these three colnames:

• "from" - regular expression patterns, which will be surrounded by "^(" and ")$" to ensure complete match.

• "sign" - character replacement for each value matched in "from" when type="sign".

• "color" - character R color to assign to each value matched in "from", when type="color".

When two or more replacement values defined by curate_df[,"sign"] are present in one entry in x, the values are concatenated together with no whitespace. For example "1 1" becomes "^^" with no spacing. To impose whitespace between characters, define sign=c("^ ", "v ") to include whitespace. Any leading/trailing whitespace will be removed afterwards.

Value

vector of labels or colors, based upon argument type.
