ドットプロットがfacet_wrap（上部のファセットラベル）でどのように表示されるかは本当に気に入っていますが、ファセットのサイズが適切になるように、スペース="free_x"を渡すことができるようにするのが理想的です。facet_gridの問題は、ファセットラベルがプロットの横に移動することです。この場合、各パネルを分離する必要があるため、これはうまく機能しません。

コードは次のとおりです。

# load data
plotdat <- structure(list(level = c("Lost (N =328)", "Won (N =75)", "Lost (N =10)",

更新 ggplot Grob を使用すると、これはかなり簡単に実行できます。こちらまたはこちらをご覧ください

ggplot グラブ バージョン 

library(ggplot2)
library(dplyr)
library(grid)

# Get the plot; plotdat data frame is below
p = ggplot(plotdat, aes(x = mean, xmin = mean-se, xmax = mean+se, y = level)) + 
    geom_point() + geom_segment( aes(x = mean-se, xend = mean+se, 
                    y = level, yend=level)) +
    facet_wrap(~var, ncol=1, scales = "free_y") +
    theme_bw() + theme(axis.title.x = element_text(size = 12, vjust = .25))+ 
    xlab("Mean V (Brightness) for Candidate's Face") + ylab("") +
    ggtitle("Skin Complexion for 2010 Minority Candidates")


# From 'plotdat', get the number of 'levels' for each 'var'.
# That is, the number y-breaks in each panel.
N <- plotdat %>% group_by(var) %>% 
   summarise(count = n()) %>% 
   `[[`(2)

# Get the ggplot grob
gt = ggplotGrob(p) 

# Get the locations of the panels in the gtable layout.
panels <- gt$layout$t[grepl("panel", gt$layout$name)]

# Replace the default panel heights with relative heights
gt$heights[panels] <- unit(N, "null")

## Draw gt
grid.newpage()
grid.draw(gt)

これはあなたの質問に答えるつもりはありません。見た目を微調整しfacet_gridます。

「各パネルが分離されている」という意味がわかりません。facet_gridプロット内のストリップ テキストがストリップの境界を超えていることが懸念される場合は、を使用してテキストを回転できますtheme(strip.text.y = element_text(angle = 0))。str_wrapさらに、 fromstingrパッケージを使用して、テキストを複数行に折り返すことができます。

# load data
plotdat <- structure(list(level = c("Lost (N =328)", "Won (N =75)", "Lost (N =10)", 
                        "Won (N =65)", "Challenger (N =318)", "Incumbent (N =85)", "Arab (N =7)",

                "mean", "se", "N", "var"), row.names = c(NA, 14L), class = "data.frame")
library('ggplot2')
library(stringr)

plotdat$var = str_wrap(plotdat$var, width = 10)

# with facet_grid:
ggplot(plotdat, aes(x = mean, xmin = mean-se, xmax = mean+se, y = level)) + 
    geom_point() + geom_segment( aes(x = mean-se, xend = mean+se,

    theme_bw() + 
    ggtitle("Skin Complexion for 2010 Minority Candidates") +
    xlab("Mean V (Brightness) for Candidate's Face") + ylab("") +
    theme(axis.title.x = element_text(size = 12, vjust = .25), 
          strip.text.y = element_text(angle = 0))

「分割するパネル」が「パネル間の追加スペース」を意味する場合theme(panel.margin = unit(2, "line")は、ロード後に, を使用しますgrid。

library(grid)
ggplot(plotdat, aes(x = mean, xmin = mean-se, xmax = mean+se, y = level)) + 
    geom_point() + geom_segment( aes(x = mean-se, xend = mean+se, 
                    y = level, yend=level)) +
    facet_grid(var~., scales = "free_y", space = "free_y") +
    theme_bw() + 
    ggtitle("Skin Complexion for 2010 Minority Candidates") +
    xlab("Mean V (Brightness) for Candidate's Face") + ylab("") +
    theme(axis.title.x = element_text(size = 12, vjust = .25), 
          strip.text.y = element_text(angle = 0),
          panel.margin = unit(2, "lines"))
