将标签添加到散点图

Question

我似乎无法在散点图中添加标签。

我想用变量states标记散点图。由于与annotate或某些其他geom函数的冲突，当前无法正常工作。

这是我的数据：

datatrials <- structure(list(states = c(
  "AP", "AR", "AS", "BR", "CH", "GJ",
  "HR", "HP", "JK", "JH", "KA", "KL", "MP", "NL", "OR", "PY", "PB",
  "RJ", "SK", "TG", "TR", "UP", "UT"

Answer 1

尝试一下。我添加了geom_text。下一个。您使用的geom_label出错，缺少datatrials$。另外，如果您添加geom = "label"，我也改用了注释。

library(ggplot2)
library(ggExtra)

# working plot
plot1 <- ggplot(datatrials, aes(SLT_preval, urbanization)) +
  geom_point(color = "#CC9933") +
  geom_smooth(fullrange = TRUE, method = "lm", level = 0.95) +
  # Add geom_text
  geom_text(aes(label = states)) +
  ylab("Urbanization %") +
  xlab("Smokeless Tobacco Use %") +
  theme(
    axis.text = element_text(size = 14),
    axis.title = element_text(size = 14)
  ) +
  scale_x_continuous(expand = c(0, 0), limits = c(0, 100)) +
  scale_y_continuous(expand = c(0, 0), limits = c(-50, 100)) +
  coord_cartesian(xlim = c(0, 70), ylim = c(0, 100)) +
  theme(axis.title.y = element_text(margin = margin(t = 0, r = 5, b = 0, l = 0))) +
  # Switch to annotate. Add geom. Add datatrials$
  annotate(
    geom = "label", x = 0.95 * max(datatrials$SLT_preval),
    y = 0.92 * max(datatrials$urbanization), size = 4.3, label = "n = 32; p-value = 0.015; \n CI = -0.799:-0.050; rho = -0.426"
  )

plot2 <- ggplot(datatrials, aes(smoking_preval, urbanization)) +
  geom_point(color = "#615513") +
  geom_smooth(fullrange = TRUE, method = "lm", se = FALSE) +
  # Add geom_text
  geom_text(aes(label = states)) +
  ylab("Urbanization %") +
  xlab("Smoking %") +
  theme(
    axis.text = element_text(size = 14),
    axis.title = element_text(size = 14)
  ) +
  scale_x_continuous(expand = c(0, 0), limits = c(0, 100)) +
  scale_y_continuous(expand = c(0, 0), limits = c(-50, 100)) +
  coord_cartesian(xlim = c(0, 70), ylim = c(0, 100)) +
  # Switch to annotate. Add geom. Add datatrials$
  annotate(geom = "label", x = 1.35 * max(datatrials$smoking_preval), y = 0.92 * max(datatrials$urbanization), size = 4.3, label = "n = 32; p-value = 0.186; \n CI = -0.641:0.165; rho = -0.239")

p1 <- ggMarginal(plot1, type = "histogram", colour = "#FF0000", fill = "#FAC95F")
#> `geom_smooth()` using formula 'y ~ x'
#> `geom_smooth()` using formula 'y ~ x'
p2 <- ggMarginal(plot2, type = "histogram", colour = "#FF0000", fill = "#615513")
#> `geom_smooth()` using formula 'y ~ x'
#> `geom_smooth()` using formula 'y ~ x'

#par(mfrow = c(1, 2))
gridExtra::grid.arrange(p1, p2, ncol = 2)
