GG_denhist still has errors

[Deleetdk]

I apparently got it not entirely right:

> GG_denhist(d, "g_noage", group = "sex")
Grouping variable contained missing values. These were removed. If you want an NA group, convert to explicit value.There were groups without any data. These were removed

Furthermore, x label is missing for non-group plot. Reprex:

> iris$Sepal.Length %>% GG_denhist()
`stat_bin()` using `bins = 30`. Pick better value with `binwidth`.

But not when group is non-NULL.

X label not an error. It's when user passes a vector. Compare:

GG_denhist(iris, "Sepal.Length") #plot overall distribution
iris$Sepal.Length %>% GG_denhist

magrittr interferes with the deparse substitute call. Won't fix.

[Deleetdk]

Error was due to unused factor levels in the grouping variable. These cases were dropped as part of the earlier fix, but apparently plyr::daply cares about levels, not unique levels.

At least, that's what I think. I could not reproduce the error with a simple attempt like:

iris %>% dplyr::filter(Species == "setosa") %>% GG_denhist(var = "Sepal.Length", group = "Species")

Fixed nonetheless.

The deparse problem is probably solvable with lazyeval.
