This page is the tutorial for source code version of the Hiplot Dist Plot plugin. You can also use the Hiplot website to achieve no code ploting. For more information please see the following link:

The dist plot is a visual diagram using a confidence distribution.

Setup

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

• Programming language: R

• Dependent packages: data.table; jsonlite; ggdist; tidyr; broom; modelr; ggplot2

# Install packages
if (!requireNamespace("data.table", quietly = TRUE)) {
  install.packages("data.table")
}
if (!requireNamespace("jsonlite", quietly = TRUE)) {
  install.packages("jsonlite")
}
if (!requireNamespace("ggdist", quietly = TRUE)) {
  install.packages("ggdist")
}
if (!requireNamespace("tidyr", quietly = TRUE)) {
  install.packages("tidyr")
}
if (!requireNamespace("broom", quietly = TRUE)) {
  install.packages("broom")
}
if (!requireNamespace("modelr", quietly = TRUE)) {
  install.packages("modelr")
}
if (!requireNamespace("ggplot2", quietly = TRUE)) {
  install.packages("ggplot2")
}

Data Preparation

The loaded data are five conditions and their corresponding values.

# Load data
data <- data.table::fread(jsonlite::read_json("https://hiplot.cn/ui/basic/ggdist/data.json")$exampleData$textarea[[1]])
data <- as.data.frame(data)

# Convert data structure
data[, 1] <- factor(data[, 1], levels = rev(unique(data[, 1])))
data <- tibble(data)
data2 = lm(response ~ condition, data = data)
data3 <- data_grid(data, condition) %>%
  augment(data2, newdata = ., se_fit = TRUE)

# View data
head(data)

# A tibble: 6 × 2
  condition response
  <fct>        <dbl>
1 A           -0.420
2 B            1.69 
3 C            1.37 
4 D            1.04 
5 E           -0.144
6 A           -0.301

Figure 1: Dist Plot

The diagram shows the confidence distribution of the mean under the conditions, and the approximate distribution of the corresponding values under the five conditions can be seen.
