object 'SpatstatVersion' not found about spatstat HOT 9 CLOSED

Are you calling these functions without attaching first? I think the environment .spEnv is generated when the spatstat package is attached. Therefore the following will generate the error you are experiencing: spatstat::versionstring.spatstat(). Is it possible for you to attach the package (e.g. via require(spatstat)) or do you need a workaround?

from spatstat.

I'm using Imports in the DESCRIPTION file of my package and then call spatstat functions using the full namespace, e.g. spatstat::mppm().
Of note, this works for some spatstat objects, such as spatstat::ppp().

I would like to avoid using require(spatstat) within my package. What would you recommend?

from spatstat.

Attaching the spatstat package via library(spatstat) in the main script that calls function of my custom package solved the problem. The user of my package shouldn't have to attach the spatstat package, however, but only my custom package (which depends on spatstat).

from spatstat.

Including spatstat in Depends in the DESCRIPTION file also solves the problem. But I think it would be nicer if spatstat would use namespaces consistently.

spatstat:::versionstring.spatstat is meant to give the version number of the currently loaded version of spatstat. I'll make a workaround for the case where spatstat is not loaded.

This problem has been fixed in the current development version (1.44-1.016). Please try this out with your custom package and let us know if it is satisfactory.

from spatstat.

Using the development version, I get

Error in do.call("ppm", append(list(...), list(rbord = rbord, justQ = TRUE)), : could not find function "ppm"

The problem also affects other functions, in my case profilepl().

from spatstat.

In spatstat development version 1.44-1.020 we have fixed this latest problem.

If you still encounter namespace problems using this version, then your package effectively requires the spatstat namespace to be imported. I'd suggest that your package DESCRIPTION file should declare that it Imports: spatstat, and the NAMESPACE file should declare either

import(spatstat)

or at least

importFrom(spatstat, ppm, profilepl, etc, etc, etc)

including the names of all the spatstat functions that are needed to prevent namespace problems.

Putting import(spatstat) in the NAMESPACE file did the trick. Thanks!
