ggprism是ggplot2的扩展包，可以让你的图形看起来像GraphPad Prism形式。使用起来非常简单，一行代码即可！支持目前Graphpad Prism的所有主题！
前面介绍了theme_prism，接下来介绍color/fill/shape！
install.packages("ggprism")
# 或使用github版
remotes::install_github("csdaw/ggprism")
提供GraphPad Prism里面常见的颜色组合，基本上都是色盲友好型，可以放心使用。
首先创建一个基本图形：
library(ggplot2)
library(ggprism)
base <- ggplot(mtcars, aes(wt, mpg)) + geom_point(aes(color = factor(cyl), shape = factor(cyl)), size = 3) +
theme_prism() + theme(legend.position = c(0.8,0.8))
base
查看所有颜色组合：
lengths(ggprism_data$colour_palettes)
## autumn_leaves beer_and_ales black_and_white blueprint blueprint2
## 9 9 9 9 9
## blueprint3 candy_bright candy_soft colorblind_safe colors
## 9 9 9 6 20
## diazo earth_tones evergreen fir fir2
## 9 10 9 9 9
## fir3 flames flames2 floral floral2
## 9 9 9 12 12
## greenwash inferno magma mustard_field mustard_field2
## 10 6 6 9 9
## muted_rainbow neon ocean ocean2 ocean3
## 10 9 9 9 9
## office pastels pearl pearl2 plasma
## 9 9 6 6 6
## prism_dark prism_dark2 prism_light prism_light2 purple_passion
## 10 10 10 10 9
## quiet quiet2 shades_of_gray spring spring2
## 9 9 9 9 9
## stained_glass stained_glass2 starry starry2 summer
## 9 9 5 5 10
## sunny_garden sunny_garden2 sunny_garden3 the_blues viridis
## 9 9 9 9 6
## warm_and_sunny warm_pastels warm_pastels2 waves waves2
## 9 9 9 5 5
## winter_bright winter_soft wool_muffler wool_muffler2 wool_muffler3
## 9 9 9 9 9
随便使用几个主题试试：
p1 <- base + scale_color_prism(palette = "autumn_leaves")
p2 <- base + scale_color_prism(palette = "ocean")
p3 <- base + scale_color_prism()
p1 + p2 + p3
先创建一个基本图：
base <- ggplot(mtcars, aes(x = wt, y = mpg)) +
geom_point(aes(fill = factor(cyl), shape = factor(cyl)), size = 3) +
theme_prism() +
theme(legend.position = c(0.8, 0.8)) +
scale_shape_prism(palette = "filled")
base
查看所有颜色组合：
lengths(ggprism_data$fill_palettes)
## autumn_leaves beer_and_ales black_and_white blueprint candy_bright
## 9 9 9 9 9
## candy_soft colorblind_safe colors diazo earth_tones
## 9 6 20 9 10
## evergreen fir flames floral greenwash
## 9 9 9 12 10
## inferno magma mustard_field muted_rainbow neon
## 6 6 9 10 9
## ocean office pastels pearl plasma
## 9 9 9 6 6
## prism_dark prism_light purple_passion quiet shades_of_gray
## 10 10 9 9 9
## spring stained_glass starry summer sunny_garden
## 9 9 5 10 9
## the_blues viridis warm_and_sunny warm_and_sunny2 warm_pastels
## 9 6 9 9 9
## waves winter_bright winter_bright2 winter_soft wool_muffler
## 5 9 9 9 9
使用几个试试看：
p1 <- base + scale_fill_prism(palette = "colorblind_safe")
p2 <- base + scale_fill_prism(palette = "neon")
p1 + p2
提供了3套形状
ggprism_data$shape_palettes
## $complete
## # A tibble: 14 x 2
## name pch
## <chr> <dbl>
## 1 circle small 16
## 2 square 15
## 3 triangle 17
## 4 diamond 18
## 5 circle filled 21
## 6 square filled 22
## 7 triangle filled 24
## 8 triangle down filled 25
## 9 diamond filled 23
## 10 asterisk 8
## 11 plus 3
## 12 cross 4
## 13 circle plus 10
## 14 square cross 7
##
## $default
## # A tibble: 9 x 2
## name pch
## <chr> <dbl>
## 1 circle small 16
## 2 square 15
## 3 triangle 17
## 4 diamond 18
## 5 asterisk 8
## 6 plus 3
## 7 cross 4
## 8 circle plus 10
## 9 square cross 7
##
## $filled
## # A tibble: 10 x 2
## name pch
## <chr> <dbl>
## 1 circle filled 21
## 2 square filled 22
## 3 triangle filled 24
## 4 triangle down filled 25
## 5 diamond filled 23
## 6 asterisk 8
## 7 plus 3
## 8 cross 4
## 9 circle plus 10
## 10 square cross 7
使用不同的形状：
base <- ggplot(mpg, aes(x = displ, y = cty)) +
geom_point(aes(colour = class, fill = class, shape = class)) +
theme_prism(base_size = 11, base_fontface = "plain", border = TRUE) +
theme(plot.subtitle = element_text(face = "bold"),
legend.position = c(0.8, 0.75),
legend.key.height = unit(10, "pt")) +
coord_cartesian(clip = "off") +
scale_colour_prism(palette = "floral") +
scale_fill_prism(palette = "floral")
p1 <- base
p2 <- base + scale_shape_prism(palette = "default") +
labs(subtitle = "default")
p3 <- base + scale_shape_prism(palette = "filled") +
labs(subtitle = "filled")
p4 <- base + scale_shape_prism(palette = "complete") +
labs(subtitle = "complete")
(p1 + p2) / (p3 + p4)
