S3 method c.tracks not exported

[burgerga]

c.tracks does not match the export pattern:

grep("^[^\\.][[:alpha:]]+", "c.tracks")
#> integer(0)

so it is not exported.

Sorry, but I don't understand -- I have the following line in NAMESPACE:

S3method(c,tracks)

And I do see the c.tracks method if I type:

getNamespaceExports("MotilityLab")

Can you comment?

Oh, that is strange, for me it's not exported on Windows or Linux, so I have to use it with MotilityLab:::c.tracks (note the triple :)
