grafify
has three main features:
grafify
or ggplot2
The vignettes website has detailed help on usage and latest release notes are here.
As an example, you could write this to plot bar/SD graph from a 2-way ANOVA data with randomised blocks:
plot_4d_scatterbar(data = data_2w_Festing,
xcol = Strain,
ycol = GST,
bars = Treatment,
shapes = Block)
instead of all this!
ggplot2::ggplot(data = data_2w_Festing,
aes(x = Strain,
y = GST,
group = interaction(Strain,
Treatment)))+
stat_summary(geom = "bar",
aes(fill = Treatment),
position = position_dodge(width = 0.8),
fun = "mean")+
geom_point(aes(shape = Block),
size = 3, stroke = 1,
position = position_jitterdodge(jitter.width = .2,
dodge.width = .8))+
stat_summary(geom = "errorbar",
width = .2, size = 1,
fun.data = "mean_sdl",
fun.args = list(mult = 1),
position = position_dodge(width = 0.8))+
scale_shape_manual(values = 21:22)+
theme_classic(base_size = 21)+
theme(axis.text.x = element_text(angle = 45, hjust = 1))+
scale_fill_manual(values = c(as.vector(graf_palettes$okabe_ito[1:2])))
Two other features including practice datasets (with randomised blocks), and data simulation for power analyses. The first three features are better documented at present.
Easily plot data as scatter/dot plots with boxes, violins or bars with plot_
functions of 6 broad types.
plot_scatterbar_sd
, plot_scatterbox
, plot_scatterviolin
or plot_dotbar_sd
, plot_dotbox
, plot_dotviolin
plot_3d_scatterbar
, plot_3d_scatterbox
, plot_3d_scatterviolin
or plot_4d_scatterbar
, plot_4d_scatterbox
, plot_4d_scatterviolin
plot_befafter_colours
, plot_befafter_shapes
, plot_befafter_box
plot_xy_NumGroup
, plot_xy_CatGroup
plot_qqline
, plot_density
plot_histogram
, and model diagnostics with plot_qqmodel
, plot_qq_gam
, plot_lm_predict
and plot_gam_predict
plot_point_sd
, plot_scatterbar_sd
, plot_3d_scatterbar
The following 12 categorical (qualitative/discreet) and 5 quantitative (3 sequential and 2 divergent) palettes are implemented in grafify
for making graphs with plot_
functions.
In addition, scale_fill_grafify
and scale_colour_grafify
functions can be used to apply all grafify
palettes to any ggplot2
object.
All palettes are colourblind-friendly. (See Mike Mol’s blog and Paul Tol’s blog. Additional colour schemes were chosen from cols4all
package).
grafify
theme & adding log-scales
The theme_grafify
function is a modification of theme_classic
and enables graphs plotted with ggplot2
to have a grafify
-like appearance.
plot_logscales
lets you take any ggplot2
object and transform Y, X or both axes into log2
or log10
values, and latter will also show log10 tick marks.

in action is the vignettes website, which has detailed description of all functions.

grafify
I made this package mainly for exploring data by quickly making graphs of different types. Secondly, to implement linear regressions for ANOVA. I also use it to introduce linear models in my teaching, including the analyses of randomised block designs to new users.
