Function in suggested packages not found. about devtools HOT 6 CLOSED

I'm not sure how to fix this bug - it's because when you load a new package it gets placed in the search path before your package, and so it can't find the functions. I'm not sure how R resolved this pre-namespaces.

You can work around it by doing load_all("pkg", T) after the package has been loaded.

For posterity, here are a couple of things that I thought might work but didn't :(

load_all("ggplot2")
setHook(packageEvent("maps", "attach"), 
  function(...) load_all("ggplot2", TRUE))
library(maps)
m <- map_data("world")

setHook(packageEvent("Hmisc", "attach"), 
  function(...) load_all("ggplot2", TRUE))
mean_cl_boot(1:100)
mean_cl_boot(1:100)

load_all("ggplot2")
setHook(packageEvent("Hmisc", "attach"), function(...) {
  env <- as.environment("package:ggplot2")
  detach("package:ggplot2")
  attach(env, name = "package:ggplot2", warn.conflicts = FALSE)
})
mean_cl_boot(1:100)

The workaround is helpful. Thanks! What about having devtools check the DESCRIPTION files for Suggests, and if it finds any, print out a message explaining the workaround?

I'd rather figure out how to solve it properly ;) I'll keep thinking about it.

There are hints at a solution at: http://stackoverflow.com/questions/8637107/parent-env-x-confusion. Devtools needs to generate an appropriate namespace environment that the package environment inherits from.

All suggested packages are now loaded automatically to work around this problem.
