Error in globalVariables(c("hue", "value", "chroma", "name", "x", "y", : could not find function "globalVariables"

Hi, when I R CMD check an in-house package 'MyPackage' of mine, I get:

─  checking whether the package can be loaded with stated dependencies ...Loading required package: TopDom
   Error in globalVariables(c("hue", "value", "chroma", "name", "x", "y",  : 
     could not find function "globalVariables"
   Error: package or namespace load failed for ‘TopDom’:
    unable to load R code in package ‘munsell’
   Error: package ‘TopDom’ could not be loaded
   Execution halted

I think the dependency on munsell' comes in via TopDom -> ggplot2, but not 100% sure. Eitherway, the above error goes away if fix 'munsell' to use importFrom(utils,globalVariables). BTW, that's the only solution I found to the problem. I'll send a PR next.
