Or do what R CMD check suggested and import the ones used, rather than all.

Which is what I had quoted earlier:

|              "terrain.colors", "tiff")
|   importFrom("graphics", "abline", "axis", "barplot", "box", "boxplot",
|              "image", "layout", "legend", "lines", "mtext", "par",
|              "plot", "plot.new", "points", "rasterImage", "strwidth",
|              "text", "title")
|   importFrom("stats", "TukeyHSD", "acf", "aov", "ccf", "coefficients",
|              "drop1", "end", "fft", "median", "model.tables",
|              "na.action", "na.omit", "pf", "ts", "var")
|   importFrom("utils", "read.table", "str", "tail", "write.table")
| 
| to your NAMESPACE file.

I find this preferable and quite appreciate that R CMD check provides it.
