Plot R dasar untuk data multivariat
pairs(iris_raw[, 1:4])
- Plot kurang berguna jika variabel banyak
Pairs plot dengan warna
pairs(iris_raw[, 1:4], col = iris_raw$Species)
Lattice
library(lattice)
splom(~iris_raw[, 1:4], col = iris_raw$Species, pch = 16)
Menggunakan ggplot
library(ggplot2)
library(GGally)
ggpairs(data = iris_raw, columns = 1:4, mapping = aes(color = Species))
Plot 3D
library(scatterplot3d)
scatterplot3d(iris_raw[, c(1, 3, 4)], color = as.numeric(iris_raw$Species))
Plot 3D
scatterplot3d(iris_raw[, c(1, 3, 4)], color = as.numeric(iris_raw$Species),pch = 4, angle = 80)
