In devOpifex/erratum: Handle Error and Warning Messages

Observe with Error Handling

Description

Observe with erratum error handling.

Usage

e.observe(
  x,
  e = NULL,
  w = NULL,
  env = parent.frame(),
  ...,
  label = NULL,
  suspended = FALSE,
  priority = 0,
  domain = shiny::getDefaultReactiveDomain(),
  autoDestroy = TRUE,
  ..stacktraceon = TRUE
)

Arguments

x	An expression (quoted or unquoted). Any return value will be ignored.
e	Error handler.
w	Warning handler.
env	The parent environment for the reactive expression. By default, this is the calling environment, the same as when defining an ordinary non-reactive expression. If x is a quosure and quoted is TRUE, then env is ignored.
...	Not used.
label	A label for the observer, useful for debugging.
suspended	If TRUE, start the observer in a suspended state. If FALSE (the default), start in a non-suspended state.
priority	An integer or numeric that controls the priority with which this observer should be executed. A higher value means higher priority: an observer with a higher priority value will execute before all observers with lower priority values. Positive, negative, and zero values are allowed.
domain	See domains.
autoDestroy	If TRUE (the default), the observer will be automatically destroyed when its domain (if any) ends.
..stacktraceon	Advanced use only. For stack manipulation purposes; see stacktrace().
