And one last note: I'm reasonably certain I haven't forgotten to
export an S3 method because I wrote the following script to (crudely)
compare the function definitions in ggplot2 with its namespace:
ns<- parseNamespaceFile("ggplot", "~/Documents/ggplot/")
s3e<- paste(ns$S3methods[, 1], ns$S3methods[, 2], sep = ".")
f<- ls("package:ggplot2")
s3<- f[str_detect(f, fixed("."))]
missing<- setdiff(s3, s3e)
missing[!str_detect(missing, "bolus|icon")]
(Code isn't reproducible, but should give you the basic idea)
I think it's this line
if (!exists(scale_name, globalenv()))
next
in scales_add_defaults, where the symbol isn't found in the globalenv()
when nstest is attached and ggplot2 only loaded, but is (via the search
path) when ggplot2 is attached.

I should add that I'm pretty sure this is something wrong with the
ggplot2 NAMESPACE because if I explicitly attach ggplot2 the code
works:
library(nstest)
my_plot()
Error in UseMethod("scale_dimension") :
no applicable method for 'scale_dimension' applied to an object of
class "NULL"
library(ggplot2)
my_plot()
# Plot appears.

Hi all,
I frequently find that I've failed to export something in my NAMESPACE
and hence my package doesn't work when it's imported into another
package. Does anyone have suggestion for debugging this type of
problem? R CMD check passes without any ns related errors on both the
importee and the importer.
I've attached a reproducible example - if you install the development
version of ggplot2 (e.g. with devtools::install_github("ggplot2") the
attached package fails R CMD check with:
### ** Examples
plot(my_plot())
Error in structure(list(data = data, layers = list(), scales = Scales$new(), :
attempt to apply non-function
Calls: plot ... my_plot -> ggplot -> ggplot.data.frame -> structure
Execution halted
Error: Command failed (1)
