theme_bruce {bruceR}R Documentation

A nice ggplot2 theme that enables Markdown/HTML rich text.

Description

A nice ggplot2 theme for scientific publication. It uses ggtext::element_markdown() to render Markdown/HTML formatted rich text. You can use a combination of Markdown and/or HTML syntax (e.g., "*y* = *x*<sup>2</sup>") in plot text or title, and this function draws text elements with rich text format.

  tag = "bold",
  plot.title = "bold",
  axis.title = "plain",

bg

Background color of whole plot. Default is "white". You can use any colors or choose from some pre-set color palettes: "stata", "stata.grey", "solar", "wsj", "light", "dust".

To see these colors, you can type:

ggthemr::colour_plot(c(stata="#EAF2F3", stata.grey="#E8E8E8", solar="#FDF6E3", wsj="#F8F2E4", light="#F6F1EB", dust="#FAF7F2"))

grid.x

FALSE, "" (default), or a color (e.g., "grey90") to set the color of panel grid (x).

grid.y

FALSE, "" (default), or a color (e.g., "grey90") to set the color of panel grid (y).

Examples

## Example 1 (bivariate correlation)
d=as.data.table(bfi)
d[,":="(E=MEAN(d, "E", 1:5, rev=c(1,2), likert=1:6),
        O=MEAN(d, "O", 1:5, rev=c(2,5), likert=1:6))]
ggplot(data=d, aes(x=E, y=O)) +
  geom_point(alpha=0.1) +
  geom_smooth(method="loess") +
  labs(x="Extraversion<sub>Big 5</sub>",
       y="Openness<sub>Big 5</sub>") +
  theme_bruce(markdown=TRUE)

## Example 2 (2x2 ANOVA)
d=data.frame(X1=factor(rep(1:3, each=2)),
             X2=factor(rep(1:2, 3)),
             Y.mean=c(5, 3, 2, 7, 3, 6),
             Y.se=rep(c(0.1, 0.2, 0.1), each=2))
ggplot(data=d, aes(x=X1, y=Y.mean, fill=X2)) +
  geom_bar(position="dodge", stat="identity", width=0.6, show.legend=FALSE) +
  geom_errorbar(aes(x=X1, ymin=Y.mean-Y.se, ymax=Y.mean+Y.se),
                width=0.1, color="black", position=position_dodge(0.6)) +
  scale_y_continuous(expand=expansion(add=0),
                     limits=c(0,8), breaks=0:8) +
  scale_fill_brewer(palette="Set1") +
  labs(x="Independent Variable (*X*)",  # italic X
       y="Dependent Variable (*Y*)",  # italic Y
       title="Demo Plot<sup>bruceR</sup>") +
  theme_bruce(markdown=TRUE, border="")
