R语言实现各种数据可视化的超详细教程

作者:WSKH0929

Python语言越来越流行,尤其是在机器学习与深度学习等领域,但是R语言在数据分析与可视化方面仍然具有绝对的优势,下面这篇文章主要给大家介绍了关于R语言实现各种数据可视化的超详细教程,需要的朋友可以参考下

1 主成分分析可视化结果

1.1 查看莺尾花数据集(前五行,前四列)

iris[1:5,-5]
##   Sepal.Length Sepal.Width Petal.Length Petal.Width
## 1          5.1         3.5          1.4         0.2
## 2          4.9         3.0          1.4         0.2
## 3          4.7         3.2          1.3         0.2
## 4          4.6         3.1          1.5         0.2
## 5          5.0         3.6          1.4         0.2

1.2 使用莺尾花数据集进行主成分分析后可视化展示

library("ggplot2")
library("ggbiplot")
## 载入需要的程辑包:plyr
## 载入需要的程辑包:scales
## 载入需要的程辑包:grid
res.pca = prcomp(iris[,-5],scale=TRUE)
ggbiplot(res.pca,obs.scale=1,var.scale=1,ellipse=TRUE,circle=TRUE)

#添加组别颜色
ggbiplot(res.pca,obs.scale=1,var.scale=1,ellipse=TRUE,circle=TRUE,groups=iris$Species)

#更改绘制主题
ggbiplot(res.pca, obs.scale = 1, var.scale = 1, ellipse = TRUE,groups = iris$Species, circle = TRUE) +
  theme_bw() +
  theme(panel.grid = element_blank()) +
  scale_color_brewer(palette = "Set2") +
  labs(title = "新主题",subtitle = "好看吗!",caption ="绘于:桂林")

2 圆环图绘制

#构造数据
df <- data.frame(
  group = c("Male", "Female", "Child"),
  value = c(10, 20, 30))
#ggpubr包绘制圆环图
library("ggpubr")
## 
## 载入程辑包:'ggpubr'
## The following object is masked from 'package:plyr':
## 
##     mutate
ggdonutchart(df, "value",
             label = "group",                               
             fill = "group",                            
             color = "white",                                
             palette = c("#00AFBB", "#E7B800", "#FC4E07") 
)

  # 添加散点
  geom_point(aes(size=cyl,color=cyl)) + 
  # 添加辅助线段
  geom_segment(aes(x=name,xend=name,y=0,yend=mpg),
               size=1, color="blue", linetype="dotdash") +

  geom_point(aes(color=cyl),size=8) + 
  # 添加辅助线段
  geom_segment(aes(x=name,xend=name,y=0,yend=mpg),
               size=1, color="gray") +
  theme_minimal() + 
  theme(
    panel.grid.major.y = element_blank(),
    panel.border = element_blank(),
    axis.ticks.y = element_blank()
  ) +
  coord_flip()

4.3 绘制棒棒糖图(使用ggpubr)

4.3.1 使用ggdotchart函数绘制棒棒糖图

ggdotchart(df, x = "name", y = "mpg",
           color = "cyl", # 设置按照cyl填充颜色
           size = 6, # 设置点的大小
           palette = c("#00AFBB", "#E7B800", "#FC4E07"), # 修改颜色画板
           sorting = "ascending", # 设置升序排序                        
           add = "segments", # 添加辅助线段
           add.params = list(color = "lightgray", size = 1.5), # 设置辅助线段的大小和颜色
           ggtheme = theme_pubr(), # 设置主题
)

4.3.2 自定义一些参数

ggdotchart(df, x = "name", y = "mpg",
           color = "cyl", # 设置按照cyl填充颜色
           size = 8, # 设置点的大小
           palette = "jco", # 修改颜色画板
           sorting = "descending", # 设置降序排序                        
           add = "segments", # 添加辅助线段
           add.params = list(color = "lightgray", size = 1.2), # 设置辅助线段的大小和颜色
           rotate = TRUE, # 旋转坐标轴方向
           group = "cyl", # 设置按照cyl进行分组
           label = "mpg", # 按mpg添加label标签
           font.label = list(color = "white", 
                             size = 7, 
                             vjust = 0.5), # 设置label标签的字体颜色和大小
           ggtheme = theme_pubclean(), # 设置主题
)

## Warning: stat_density_tern: You have not specified a below-detection-limit (bdl) value (Ref. 'bdl' and 'bdl.val' arguments in ?stat_density_tern). Presently you have 2x value/s below a detection limit of 0.010, which acounts for 2.000% of your data. Density values at fringes may appear abnormally high attributed to the mathematics of the ILR transformation. 
## You can either:
## 1. Ignore this warning,
## 2. Set the bdl value appropriately so that fringe values are omitted from the ILR calculation, or
## 3. Accept the high density values if they exist, and manually set the 'breaks' argument 
##    so that the countours at lower densities are represented appropriately.

nrows <- 10
ndeep <- 10
unit<-100
df <- expand.grid(y = 1:nrows, x = 1:nrows)

categ_table <- as.data.frame(table(mpg$class) * (nrows*nrows))

6.1.4 waffle 包绘制(一个好用的包,专为华夫饼图做准备的)

#parts 用于图表的值的命名向量
#rows 块的行数
#keep 保持因子水平(例如,在华夫饼图中获得一致的图例)
library("waffle")
parts <- c(One=80, Two=30, Three=20, Four=10)
chart <- waffle(parts, rows=8)
print(chart)

7 三维散点图绘制

7.1 简单绘制

library("plot3D")
#以Sepal.Length为x轴,Sepal.Width为y轴,Petal.Length为z轴。绘制箱子型box = TRUE;旋转角度为theta = 60, phi = 20;透视转换强度的值为3d=3;按照2D图绘制正常刻度ticktype = "detailed";散点图的颜色设置bg="#F57446"
pmar <- par(mar = c(5.1, 4.1, 4.1, 6.1)) #改版画布版式大小
with(iris, scatter3D(x = Sepal.Length, y = Sepal.Width, z = Petal.Length,
  pch = 21, cex = 1.5,col="black",bg="#F57446",
                   xlab = "Sepal.Length",
                   ylab = "Sepal.Width",
                   zlab = "Petal.Length", 
                   ticktype = "detailed",bty = "f",box = TRUE,
                   theta = 60, phi = 20, d=3,
                   colkey = FALSE)
)

7.2 加入第四个变量,进行颜色分组

7.2.1 方法一

#可以将变量Petal.Width映射到数据点颜色中。该变量是连续性,如果想将数据按从小到大分成n类,则可以使用dplyr包中的ntile()函数,然后依次设置不同组的颜色bg=colormap[iris$quan],并根据映射的数值添加图例颜色条(colkey())。
library(tidyverse)
iris = iris %>% mutate(quan = ntile(Petal.Width,6))
colormap <- colorRampPalette(rev(brewer.pal(11,'RdYlGn')))(6)#legend颜色配置
pmar <- par(mar = c(5.1, 4.1, 4.1, 6.1))
# 绘图
with(iris, scatter3D(x = Sepal.Length, y = Sepal.Width, z = Petal.Length,pch = 21, cex = 1.5,col="black",bg=colormap[iris$quan],
     xlab = "Sepal.Length",
     ylab = "Sepal.Width",
     zlab = "Petal.Length", 
     ticktype = "detailed",bty = "f",box = TRUE,
     theta = 60, phi = 20, d=3,
     colkey = FALSE)
)
colkey (col=colormap,clim=range(iris$quan),clab = "Petal.Width", add=TRUE, length=0.4,side = 4)

7.2.2 方法二

#将第四维数据映射到数据点的大小上(cex = rescale(iris$quan, c(.5, 4)))这里我还“得寸进尺”的将颜色也来反应第四维变量,当然也可以用颜色反应第五维变量。
pmar <- par(mar = c(5.1, 4.1, 4.1, 6.1))
with(iris, scatter3D(x = Sepal.Length, y = Sepal.Width, z = Petal.Length,pch = 21, 
                     cex = rescale(iris$quan, c(.5, 4)),col="black",bg=colormap[iris$quan],
                     xlab = "Sepal.Length",
                     ylab = "Sepal.Width",
                     zlab = "Petal.Length", 
                     ticktype = "detailed",bty = "f",box = TRUE,
                     theta = 30, phi = 15, d=2,
                     colkey = FALSE)
)
breaks =1:6
legend("right",title =  "Weight",legend=breaks,pch=21,
       pt.cex=rescale(breaks, c(.5, 4)),y.intersp=1.6,
       pt.bg = colormap[1:6],bg="white",bty="n")

7.3 用rgl包的plot3d()进行绘制

library(rgl)
#数据
mycolors <- c('royalblue1', 'darkcyan', 'oldlace')
iris$color <- mycolors[ as.numeric(iris$Species) ]
#绘制
plot3d( 
  x=iris$`Sepal.Length`, y=iris$`Sepal.Width`, z=iris$`Petal.Length`, 
  col = iris$color, 
  type = 's', 
  radius = .1,
  xlab="Sepal Length", ylab="Sepal Width", zlab="Petal Length")
