Create example glyphs for valr functions.

Source: R/bed_glyph.r
bed_glyph.Rd

Used to illustrate the output of valr functions with small examples.

Usage

bed_glyph(expr, label = NULL)

Arguments

expr

expression to evaluate

label

column name to use for label values. should be present in the result of the call.

Value

ggplot2::ggplot()

Examples

x <- tibble::tribble(
  ~chrom, ~start, ~end,
  "chr1", 25,     50,
  "chr1", 100,    125
)

y <- tibble::tribble(
  ~chrom, ~start, ~end, ~value,
  "chr1", 30, 75, 50
)

bed_glyph(bed_intersect(x, y))
#> Warning: The `min_overlap` argument of `bed_intersect()` is deprecated as of valr 0.8.0.
#> ℹ The default will change from 0 (book-ended intervals overlap) to 1 (strict
#>   overlap) in a future version.
#> ℹ Set `min_overlap = 0L` to keep the legacy behavior, or `min_overlap = 1L` for
#>   bedtools-compatible behavior.


x <- tibble::tribble(
