Or do what R CMD check suggested and import the ones used, rather than all.
Which is what I had quoted earlier:

| importFrom("grDevices", "as.raster", "dev.cur", "dev.off", "gray",
| "heat.colors", "jpeg", "palette", "pdf", "png", "rainbow",
| "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.
