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
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
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],

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.
and topenv(parent.frame()) is a replacement that gets to .GlobalEnv for
ggplot2, and to the name space for nstest.
