You can easily switch between magrittr pipe `%>%` and base pipe `|>` in the RStudio settings 🧰

This is how you can highlight a subset of the dataset in #tidyplots 🔥

library(tidyplots) animals |> tidyplot(x = weight, y = size) |> add_data_points() |> add_data_points(data = max_rows(weight, n = 3), color = "red", shape = 1, size = 3)

This is how you can plot z-scores in #tidyplots heatmaps 🚀

This is especially useful when you want to focus on the dynamics within rows or columns.

This is how you can add the mean and standard deviation to summarize the raw data points in your #tidyplots 🤩

Alternatively, you can also display the median, standard error of the mean, 95% confidence interval, and more.

#rstats #dataviz #phd
library(tidyplots) climate |> tidyplot(x = month, y = max_temperature) |> add_data_points_beeswarm(alpha = 0.3, color = "grey") |> add_mean_line(linewidth = 0.5) |> add_sd_ribbon()

These are the discrete color schemes in #tidyplots 🌈

The default scheme `colors_discrete_friendly` is inspired by Okabe and Ito (2008) and was designed to be accessible for individuals with color vision deficiencies.

This is the grammar for summary statistics in #tidyplots 🤩

You can mix and match as you like.

This is how you can label selected data points in #tidyplots 🔥

In this case, we label the three animals with the highest weight using `max_rows()`.

#rstats #dataviz #phd
library(tidyplots) animals |> tidyplot(x = weight, y = size) |> add_data_points() |> add_data_labels_repel(data = max_rows(weight, n = 3), label = animal, color = "black")

This is how you can define a custom style to reuse it across several #tidyplots 🤩

#rstats #dataviz #phd
library(tidyplots) my_style <- function(x) { x |> adjust_colors(colors_discrete_apple) |> adjust_font(family = "mono", face = "bold") |> remove_x_axis_ticks() |> remove_y_axis_ticks() } energy_week |> tidyplot(date, power, color = energy_source) |> add_areastack_relative() |> my_style()

Too many vector shapes can slow down PDF performance. This is how you can selectively rasterize data points in #tidyplots 🪩

In this example, I used 100 DPI for demonstration purposes. In practice, you would typically use 300 DPI for better quality 😉

#rstats #dataviz #phd
library(tidyplots) climate |> tidyplot(x = month, y = max_temperature) |> add_data_points_beeswarm(white_border = TRUE, rasterize = TRUE, rasterize_dpi = 100)

When you execute a #tidyplots color scheme like `colors_continuous_viridis` in the Console, you will get a preview in the RStudio Viewer pane 🌈

Pro tip: You can highlight and copy individual hex codes directly from the Viewer pane.

This is how you can split a plot into multiple subplots using #tidyplots 🚀

#rstats #dataviz #phd
library(tidyplots) gene_expression |> head(n = 180) |> tidyplot(x = group, y = expression, color = group) |> add_mean_bar(alpha = 0.3) |> add_sem_errorbar() |> add_data_points_beeswarm(white_border = TRUE) |> adjust_size(width = 25, height = 25) |> split_plot(by = external_gene_name, ncol = 3, nrow = 3)

This is how you can generate multiple PDF files at once in #tidyplots 🚀

You can save #tidyplots in multiple formats by piping through multiple rounds of `save_plot()` 🤩

#rstats #dataviz #phd
library(tidyplots) study |> tidyplot(x = group, y = score, color = dose) |> add_mean_dash() |> add_sem_errorbar() |> add_data_points_beeswarm() |> save_plot("my_plot.pdf") |> save_plot("my_plot.png") |> save_plot("my_plot.svg")
