[Rd] Problem with accessing internal variable in package.

I am writing a package, which contains several functions and variables. The variables are for internal use by functions. Functions are ment to be callable by a user. However, the function cannot access these variables.

The package contains only R code, and was created using package.skeleton



Among others, the package contains the functions EstimC, AB2C, AB2C.S, and AB2C.HK, and variables ac9nw, ac9wl, ac9aw, ... Functions use these variables for calculations, and I would like to hide them from users.

The file NAMESPACE contains the single line:   export(AB2C.HK,AB2C,AB2C.S,EstimC,plot.C,read.AC9.data,plot.AC9)

I am getting the following error:
Error in AB2C(a, b, model.type) : object "ac9nw" not found

> traceback()

2: AB2C(a, b, model.type)
1: EstimC(i, plot.base.name = paste(plt.base.name, "S_", sep = ""),

       model.type = "S")
