Subject: Remove grey area when using gplot (rasterVis)
In-Reply-To: <CABkCotQjotTM3q59n8p4CS8i=83G6MhPrzfYEkf-8wC+4Ooq-w@mail.gmail.com>
Hello,
Use na.value='transparent' inside scale_fill_gradient:
theme_set(theme_bw())
gplot(s) + geom_tile(aes(fill = value)) +
facet_wrap(~ variable) +
scale_fill_gradient(low = "white", high = "blue", na.value='transparent') +
coord_equal()
Best,
Oscar
