Dear Glenn,
Suppose this function
test <- function(df){
ggplot(df, aes(x = gp, y = y)) + geom_point()
}
Then R CMD check will consider gp and y as global variables since they are
undefined. Because R CMD check cannot detect that gp and y will be
extracted from df by ggplot2.
Possible workarounds
# now gp and y are defined within the function. ggplot2 still looks for gp
and y in df.
test <- function(df){
gp <- NULL
y <- NULL
ggplot(df, aes(x = gp, y = y)) + geom_point()
}
# now "gp" and "y" are strings and hence defined
test <- function(df){
ggplot(df, aes_string(x = "gp", y = "y")) + geom_point()
}

than asking him to perform a post-mortem examination: he may be able to say
what the experiment died of. ~ Sir Ronald Aylmer Fisher

The combination of some data and an aching desire for an answer does not
ensure that a reasonable answer can be extracted from a given body of data.
