Explore using {callr} to launch shine gadgets in background

[lianos]

There may be a way to launch shiny gadgets on a separate thread using callr.

This launches a background R process that seems to be doing something, but I can't find a shiny app anywhere in sight when I hit 127.0.0.1:PORT (7575 here) when I specify the port via global option:

options("shiny.port" = 7575)
efds <- FacileData::exampleFacileDataSet()
dge <- efds %>%
  FacileData::filter_samples(indication == "BLCA") %>%
  flm_def(covariate = "sample_type", numer = "tumor", denom = "normal") %>%
  fdge(mdef, method = "voom")

bg3 <- callr::r_bg(
  shine, 
  list(dge, viewer = "browser"), 
  stdout = "/Users/lianoglou/tmp/log.txt")

• Someone asked how to do something like this, but using the RStudio Jobs pane was the solution provided, but using callr was suggested as an alternative

Similar to #44 this is possible via job() with some limitations

job::job({options("shiny.port" = 7575); shiny::runApp(shine(vdge, viewer = "browser"))})
