library(hgchmagic)
hgchmagic has a set of functions to assists users when plotting data. Here you´ll see how to use it.
The core function to plot a bar plot with hgchmagic is hgch_bar()
# Load libraries library(ggplot2) library(dsdataprep) # Load the data data <- diamonds data <- aggregation_data(data = data, agg = "sum", group_var = "cut", to_agg = "price") # Plot hgch_bar(data, var_cat = "cut", var_num = "price")
# Load libraries library(ggplot2) library(dplyr) # Load the data data <- diamonds data <- data |> select(carat, x, everything()) # plot hgch_scatter(data, var_num = c("x", "carat"))
# Load libraries library(lubridate) library(tidyr) library(dplyr) # Load the data data <- lakers data$date <- ymd(data$date) data <- data |> drop_na(x) |> group_by(date) |> summarise(x = sum(x)) |> arrange(date) # Plot hgch_line(data, var_dat = "date", var_num = "x", hor_title = "fecha", ver_title = "valor")
# Load libraries library(ggplot2) library(dsdataprep) # Load the datas data <- diamonds data <- aggregation_data(data = data, agg = "sum", group_var = "cut", to_agg = "price") # Plot hgch_pie(data = data, var_cat = "cut", var_num = "price")
# Load libraries library(ggplot2) library(dplyr) # Load the datas data <- diamonds data <- data |> group_by(cut, clarity) |> summarise(total = sum(z, na.rm = T)) hgch_sankey(data, var_cat = c("cut", "clarity"), var_num = "total")
# Load libraries library(ggplot2) library(dplyr) # Load the data data <- diamonds |> select(cut, everything()) # Plot hgch_treemap_Cat(data)
Plots with hgchmagic can be easily improved by adding some labels of information like titles, subtitles, caption, etc.:
# Load libraries library(ggplot2) library(dplyr) ### hgch_bar_Cat() data <- diamonds |> select(cut, everything()) ## List with different custom settings for the plot ops <- list(title = "This is a title", subtitle = "This is a subtitle", caption = "A caption? Yes, this is a caption", hor_title = "Categories", ver_title = "Numbers", bar_orientation = "hor") # Plot hgch_bar(data, var_cat = "cut", var_num = "price", opts = ops)
hgchmagic can help you plotting identifying different types of variables in the data frame. For example, when having a Categorical variable the hgch_bar_Cat()
function could be more helpful:
### hgch_bar_Cat() hgch_bar_Cat(data, opts = ops, palette_colors = "#ffa92a")
More functions that plots according to variable types:
data <- diamonds |> select(cut, color, price, everything()) hgch_bar_CatCat(data, opts = ops)
hgch_bar_CatCatNum(data, opts = ops)
Plots with custom theme setted on opts argument:
# Data data <- diamonds |> select(cut, everything()) # opts from theme (canvas) test_theme <- list( theme = list( background_color = "#2f2f2f", plot_margin_bottom = 30, plot_margin_left = 30, plot_margin_right = 30, plot_margin_top = 30, plot_background_color = "#f2f2f2", plot_border_color = "#ff2c2f", plot_border_size = 3, text_family = "ubuntu", text_size = 15 ) ) # Plot hgch_bar_Cat(data, opts = test_theme)
