Generating Publication-Ready Figures in R

This skill specializes in transforming ordinary ggplot2 plots into professional, publication-ready figures that meet the strict standards of top-tier journals like Nature, Science, Cell, and others.

Use this skill when the user wants to:

Convert ggplot plots to journal-style figures

Apply Nature/Science publication themes to existing plots

Create multi-panel figures with consistent styling

Export figures with proper DPI, dimensions, and formats

Match specific journal submission guidelines

Create colorblind-safe and publication-quality color schemes

---

What This Skill Does

When activated, this skill will:

1. Analyze existing ggplot code - Read and understand the current plot structure

2. Apply journal themes - Add publication-quality themes including: - Proper font sizes and families - Clean axis lines and backgrounds - Journal-specific color palettes - Legend positioning and styling

3. Optimize for submission - Ensure figures meet: - DPI requirements (typically 300-600 DPI) - Width/height specifications (single vs double column) - File format requirements (TIFF, PDF, EPS) - Color space requirements (CMYK vs RGB)

4. Create multi-panel figures - Combine plots using: - patchwork for simple layouts - cowplot for complex compositions - Custom annotation and labeling

5. Export properly - Save with correct: - Resolution (DPI) - Dimensions (inches/cm) - File format - Color profile

Color Palettes

Nature-Approved Colors

  blue = "#3B4992",
  red = "#EE0000",
  green = "#008B45",
  purple = "#631879"
)

Colorblind-Safe Scales

scale_fill_viridis()

scale_color_okabe_ito() (Okabe-Ito palette)

scale_color_viridis()

Example Workflow

User: Here's my ggplot code, make it Nature-style.

# Original plot
p <- ggplot(mtcars, aes(x = wt, y = mpg, color = factor(cyl))) +
  geom_point(size = 3)

Skill transforms to:

# Publication-ready version
p <- ggplot(mtcars, aes(x = "Weight (tons)", y = "Fuel Efficiency (mpg)",
                        color = "Cylinders")) +
  geom_point(size = 2.5, shape = 16, alpha = 0.8) +
  scale_color_nature() +
  theme_nature(base_size = 8) +
  labs(title = NULL)
Export at correct size
ggsave("figure1.pdf", p, width = 3.5, height = 3, dpi = 300,
       device = "pdf")

---

Multi-Panel Figures

# Combine plots with patchwork
library(patchwork)
figure1 <- (panel_a | panel_b) / (panel_c | panel_d)
Add panel labels
figure1 <- figure1 +
  plot_annotation(tag_levels = "A",
                  tag_suffix = ")")
Export
ggsave("figure1.pdf", figure1, width = 7, height = 6, dpi = 300)

Quick Reference

Applying a theme

p + theme_nature()           # Nature style
p + theme_science()          # Science style
p + theme_cellpress()        # Cell Press style
p + theme_colorblind()       # Colorblind-safe

Export formats

# Vector (preferred)
ggsave("figure.pdf", ... device = "pdf")
ggsave("figure.eps", ... device = "eps")
Raster (high DPI)
ggsave("figure.tiff", ... device = "tiff", dpi = 600)
ggsave("figure.png", ... device = "png", dpi = 300)

Common fixes

Text too small: Increase base_size in theme

Legend overlap: Use theme(legend.position = "bottom")

Colors not distinct: Use scale_fill_viridis()

Fonts not rendering: Use extrafont::font_import()

Notes

Always check specific journal guidelines before submission

Vector formats (PDF/EPS) are preferred over raster

Use consistent styling across all figures in a paper

Test colorblind accessibility with colorblindr package

Keep axis labels clear and concise

Avoid redundant chart junk (backgrounds, grid lines)
