factoextra:抖动标签以避免过度绘制
factoextra: jitter labels to avoid overplotting
由于factoextra
使用ggplot2
绘图系统,有没有办法调整文本标签的位置(抖动)以避免重叠?
# install.packages("devtools","FactoMineR")
# library("devtools")
# install_github("kassambara/factoextra")

library("factoextra")
data(poison)
poison.active <- poison[1:55, 5:15]
res.mca <- MCA(poison.active, graph = FALSE)
fviz_mca_ind(res.mca)
factoextra:减少过度绘制
参数 jitter 现在可以在 factoextra 包中使用并记录在:http://www.sthda.com/english/wiki/factoextra-reduce-overplotting-of-points-and-labels-r-software-and-data-mining.
Install the latest version of factoextra (>= 1.0.3) as follow:
# install.packages("devtools")
devtools::install_github("kassambara/factoextra")
计算多重对应分析
library("FactoMineR")
library("factoextra")
# Load data
data(poison)
poison.active <- poison[1:55, 5:15]
# Compute MCA
res.mca <- MCA(poison.active, graph = FALSE)
默认情节
# Default plot
fviz_mca_ind(res.mca)
使用抖动减少重叠
Use jitter to reduce overplotting
fviz_mca_ind(res.mca, jitter = list(width = 0.3, height = 0.3))
注意参数 jitter 是 width 和 height 参数的列表:
- width:x方向的抖动程度
- height: y方向的抖动程度
