R软件包依赖关系的问题

Question

I created an R package which has certain dependencies on other packages. So i specified the package name as Imports and Depends in the Description file. In the namespace file I specified that the package should be exported. I checked the writing R extensions manual and there doesn't seem to be anything else that I should add.

When I try running the package it is not able to call the functions on which the package depends.Do I need to specify additional parameters to be able to call those functions.

I am using R version 2.15.0

Please help me out with this problem.

Thanks.

NAMESPACE:
import("RHive")
export("bigEDA")
export("procFreq")
export("procUnivariate")

I want all the functions from RHive to be present in the same environment as my package. Just not able to do that. I have tried specifying export("RHive") and exportFrom("RHive","rhive.query") This also doesn't work. :(

Did you run R CMD check NAMEofYOURpackage in your terminal or shell to test whether your DESCRIPTION and NAMESPACE file are fine? This check routine creates the file 00install.out that can give you a hint where something went wrong.

If you just want to use functions from foreign packages in your package use the DESCRIPTION file. There you just type: Depends: RHive

Use the export in the NAMESPACE file to export your functions to the user. If you have a function sum() and you want the user who installed your package to be able to use this function use: exportMethods(sum) (you can add more functions right here by separating them with commas)
