Shiny bindings for visual_diff() — visual_diff

Use visual_diff_output() in ui and render_visual_diff(visual_diff(...)) in the server function.

visual_diff_output(outputId, width = "100%", height = "400px")

visual_diff_render(expr, env = parent.frame(), quoted = FALSE)

Arguments

outputId: output variable to read from
width, height: Must be a valid CSS unit (like '100%', '400px', 'auto') or a number, which will be coerced to a string and have 'px' appended.
expr: An expression that generates a visual_diff
env: The environment in which to evaluate expr.
quoted: Is expr a quoted expression (with quote())? This is useful if you want to save an expression in a variable.

Value

Components for use inside a Shiny app.

if (require("shiny") && interactive()) {
ui <- fluidPage(
  visual_diff_output("diff")

server <- function(input, output, session) {
  path1 <- tempfile()
  path2 <- tempfile()
  writeLines(letters, path1)
  writeLines(letters[-13], path2)

  output$diff <- visual_diff_render(visual_diff(path1, path2))
}
