Add "lasso_select" tool to a Bokeh figure

Add "lasso_select" tool to a Bokeh figure

tool_lasso_select(
  fig,
  callback = NULL,
  ref_layer = NULL,
  line_color = "black",
  line_alpha = 1,
  fill_color = "lightgrey",
  fill_alpha = 0.5,
  line_width = 2,
  line_dash = c(4, 4),
  level = "overlay"
)

Arguments

fig	figure to modify
callback	a callback to be applied to this tool - either a character string of javascript code or any one of debug_callback, shiny_callback, console_callback, custom_callback
ref_layer	name of the layer that the callback should be applied to
line_color, line_alpha, fill_color, fill_alpha, line_width, line_dash, level	parameters to control the look of the selection bounding region

Note

Tools can be easily specified as a vector of tool names in the tools argument when instantiating a figure. In this case, they are added with defaults. Explicitly calling these tool_ functions will manually add the tool to a figure and allow additional specification of parameters.
