still having some problems with creating R-package. I'm trying to organize some import dependencies to my package and this seems to go wrong.

I setup my DESCRIPTION-file as shown below and when i call the first method i get an error. It seems like the workspace still missing the import which leeds to my first question:

Package: Concentration
Type: Package
Title: A package for Concentration
Version: 1.0
Date: 2015-08-10
Author: I'm the author
Maintainer: I'm the maintainer
Description: This package implements XXXXX
Depends: R (>= 0.98.1103)
Imports:
    XLConnect,
    ggplot2,
    scales
License: HAW-Ostfalia / Brunschwig

1- how do i properly organize import with CRAN/Roxygen

2- I've got some functions in my package which depend on others in the same package. How can I make sure R-CMD automatically recognizes/calls them in the runtime?

Hier ist the error i get:

> library(Concentration)
> xy <- extract.xy("1 AR Procymidone.xlsx")
Error in extract.xy("1 AR Procymidone.xlsx") : 
  konnte Funktion "loadWorkbook" nicht finden

Which means much like the method "extract.xy" can't find "loadWorkbook". Has anybody an idea how it works? Thanks.

    Are you sure about this line: `Depends: R (>= 0.98.1103)`? That looks like an RStudio / RStudio Server version number rather than an R version number... – nrussell Mar 22 '16 at 15:44
  • i use a Mac-version... I guess, it's not the same as windows? Don't know... – Lycone Mar 22 '16 at 18:21
  • @Lycone it is not a matter for of OS, but the R. Looks like the version you used is RStudio version, which is not R, it is an IDE for R. – jangorecki Mar 22 '16 at 22:56
