# The tactile theme

### tactile

tactile introduces a new theme for latice that does a few things, namely

- minimizes paddings around the plot,
- halves axis tick lengths,
- uses a color theme based on RColorBrewer,
- decreases title size slightly,
- Sets strip backgrounds to grey.

We now turn to illustrating the differences. First, we use `lattice::show.settings()` for an overview over the default settings.

    library(tactile)
    show.settings()
    show.settings(tactile.theme())

Then we plot a sample plot (from http://latticeextra.r-forge.r-project.org/).

    set.seed(0)

    ## create a plot to demonstrate graphical settings
    obj <- xyplot(Sepal.Length + Sepal.Width ~ Petal.Length + Petal.Width, iris,
                  type = c("p", "r"), jitter.x = TRUE, jitter.y = TRUE, factor = 5,
                  auto.key = list(lines = TRUE, rectangles = TRUE))
    obj <- update(obj,
                  legend = list(right = list(fun = "draw.colorkey",
                                             args = list(list(at = 0:100)))))

    ## draw with default theme
    obj

    ## draw with tactile.theme()
    update(obj, par.settings = tactile.theme())
