[Rd] package check note: no visible global function definition (in functions using Tcl/Tk)

[Thomas Petzoldt]

Hello,

when testing packages under R version 2.6.0 Under development 
(unstable), in order to discover future compatibility issues, I recently 
get numerous "possible problem notes" for different (own and other 
contributed) packages containing Tcl/Tk code,  e.g.:


   * checking R code for possible problems ... NOTE
   sEdit : editVec : build: no visible global function
   definition for 'tclvalue'
   sEdit : editVec : reset: no visible global function
   definition for 'tclvalue<-'
   sEdit : editVec: no visible global function
   definition for 'tktoplevel'


My question:

- Is this an indication of a serious problem?
- How can one avoid (or if not possible suppress) these messages?

Thanks in advance
