在R中的同一个图中排列许多图

Question

我想在一个图中使用不同的图形，但是我使用的命令 (grid.arrange) 扭曲了图表的条形图。除此之外，我想将每个图表的标题（A、B、C ..）放在图表的顶部，而不是它显示的侧面。

在图 1 中，我有一个图表（正确的条），在第二个图表中，所有图表都放在一起。有人可以帮我重新调整这个命令吗？

谢谢

Answer 1

你可以试试：

library(dplyr)

dados %>%
  gather(type, value, -c("specie", "bodymass", "trophic")) %>%
  ggplot(aes(x=specie, y=value)) + geom_col(alpha=0.5, aes(color=trophic, fill=trophic, group=trophic)) +
  facet_wrap(~type, ncol=3) +
  theme(axis.text.x = element_text(angle=55))

编辑：

要控制trophic的颜色，需要把它从连续变量改成因子：

dados %>%
  gather(type, value, -c("specie", "bodymass", "trophic")) %>%
  mutate(trophic = as.factor(trophic)) %>%
  ggplot(aes(x=specie, y=value)) + geom_col(alpha=0.5, aes(color=trophic, fill=trophic, group=trophic)) +
  facet_wrap(~type, ncol=3) +
  scale_fill_manual("trophic", values = c("#66FF33", "#FFFF00", "#FFCC99")) +
  scale_color_manual("trophic", values = c("#66FF33", "#FFFF00", "#FFCC99")) +
  theme(axis.text.x = element_text(angle=55))

Answer 2

这是一个使用 graphics 的解决方案（仅作为使用 layout 和自定义函数的大纲）：

addfiglab <- function(lab, xl = par()$mar[2], yl = par()$mar[3], cex = 1) {

  text(x = line2user(xl, 2), y = line2user(yl, 3), 
       lab, xpd = NA, font = 2, cex = cex, adj = c(0, 1))

}

line2user <- function(line, side, outer = FALSE) {
  unit <- if (outer) "nic" else "npc"
  lh <- par('cin')[2] * par('cex') * par('lheight')
  x_off <- diff(grconvertX(c(0, lh), 'inches', unit))
  y_off <- diff(grconvertY(c(0, lh), 'inches', unit))
  switch(side,
         `1` = grconvertY(-line * y_off, unit, 'user'),
         `2` = grconvertX(-line * x_off, unit, 'user'),
         `3` = grconvertY(1 + line * y_off, unit, 'user'),
         `4` = grconvertX(1 + line * x_off, unit, 'user'),
         stop("Side must be 1, 2, 3, or 4", call.=FALSE))
}

layout(matrix(c(rep(1, 9), 2:10), ncol = 3, byrow = TRUE))
plot(1:10); addfiglab("A")
for (i in 2:10) {plot(i); addfiglab(LETTERS[i])}
