jcolors
introjcolors
contains a selection of ggplot2
color palettes that I like (or can at least tolerate to some degree)
Install jcolors
from GitHub:
Access the jcolors
color palettes with
jcolors()
:
## kelly_green rich_electric_blue maximum_red majorelle_blue
## "#29BF12" "#00A5CF" "#DE1A1A" "#574AE2"
## fluorescent_orange
## "#FFBF00"
ggplot2
Now use scale_color_jcolors()
with
ggplot2
:
library(ggplot2)
library(gridExtra)
data(morley)
pltl <- ggplot(data = morley, aes(x = Run, y = Speed,
group = factor(Expt),
colour = factor(Expt))) +
geom_line(size = 2) +
theme_bw() +
theme(panel.background = element_rect(fill = "grey97"),
panel.border = element_blank(),
legend.position = "bottom")
pltd <- ggplot(data = morley, aes(x = Run, y = Speed,
group = factor(Expt),
colour = factor(Expt))) +
geom_line(size = 2) +
theme_bw() +
theme(panel.background = element_rect(fill = "grey15"),
legend.key = element_rect(fill = "grey15"),
panel.border = element_blank(),
panel.grid.major = element_line(color = "grey45"),
panel.grid.minor = element_line(color = "grey25"),
legend.position = "bottom")
grid.arrange(pltl + scale_color_jcolors(palette = "default"),
pltd + scale_color_jcolors(palette = "default"), ncol = 2)
grid.arrange(pltl + scale_color_jcolors(palette = "pal2"),

Color palettes can be displayed using
display_jcolors()
grid.arrange(pltl + scale_color_jcolors(palette = "pal3"),

grid.arrange(pltl + scale_color_jcolors(palette = "pal4"),

theme(panel.background = element_rect(fill = "grey5")), ncol = 2)
grid.arrange(pltl + scale_color_jcolors(palette = "pal5"),
pltd + scale_color_jcolors(palette = "pal5"), ncol = 2)
pltd <- ggplot(data = OrchardSprays, aes(x = rowpos, y = decrease,
group = factor(treatment),
colour = factor(treatment))) +
geom_line(size = 2) +
geom_point(size = 4) +

plt2 <- plt + scale_fill_jcolors_contin("pal2", bias = 1.75) + theme_bw()
