Two-dimensional spatial scatter to demonstrate multi-numerical variable relationships.

Setup

  • System Requirements: Cross-platform (Linux/MacOS/Windows)

  • Programming language: R

  • Dependent packages: grafify; ggplot2

# Install packages
if (!requireNamespace("grafify", quietly = TRUE)) {
  install.packages("grafify")
}
if (!requireNamespace("ggplot2", quietly = TRUE)) {
  install.packages("ggplot2")
}

# Load packages
library(grafify)
library(ggplot2)

Data Preparation

# Load data
data <- read.delim("files/Hiplot/162-scatter2-data.txt", header = T)

# View data
head(data)
