[R-pkg-devel] Warning about ggplot although no ggplot is used anywhere in the package

[Alexandre Courtiol]

In rstanarm, the function posterior_vs_prior and pp_validate use
bayesplot::grid_lines which is defined as:

function (color = "gray50", size = 0.2)
{
    theme(panel.grid.major = element_line(color = color, size = size),
        panel.grid.minor = element_line(color = color, size = size *
            0.5))
}

so bayesplot seems to be the culprit if you use these functions.
