ggplot2 - R CMD check NOTEs on ggplot, subset, etc -

-

when using ggplot or subset, r cmd check command on package generates following notes:

* checking r code possible problems ... note foo: no visible binding global variable ‘bar’

for mock function such 

foo <- function(dataframe) { subset(dataframe,bar>10) }

that r cmd check section useful when forgetting usage of global variables in package. therfore i'd have clean.

is there possibility let r know of special nature of ggplot/subset?

that's reason note not warning or error - there's no automated way detect use of non-standard evaluation in function.
