在R（joyplot）中使用ggridges的周期性错误

我目前正在使用ggridges库，以制作'joychart'。我写了这个：在R（joyplot）中使用ggridges的周期性错误

data3 %>% 
    mutate(ftFct = fct_rev(as.factor(ft_newnum))) %>% 
    ggplot(aes(y = ftFct)) + 
    geom_density_ridges(aes(x = ft, fill = paste(ftFct, rep)), 
         alpha = .8, color = "white", from = 0, to = 100) + 
    labs(x = "Feeling Themometer Responses (%)", 
    y = " ", 
    title = "Republican vs Democratic Views Towards...", 
    subtitle = "Analysis unit: students (n = 595)") + 
    scale_y_discrete(expand = c(0.01, 0)) + 
    scale_x_continuous(expand = c(0.01, 0)) + 
    scale_fill_cyclical(breaks = c("2 0", "2 1"), 
         labels = c(`2 0` = "Democrat", `2 1` = "Republican"), 
         values = c("#8080ff", "#ff8080", "#0000ff", "#ff0000"), 
         name = "Political Affiliation", guide = "legend") + 
    theme_ridges(grid = FALSE)

...这让我这个数字：

这正是我想要的 - 完美的格式，以及光影色彩之间每行交替，提供一些对比度和增加的可读性。

接下来，我标记y轴变量，以便我们知道我们正在看什么。我的标签 'ft_newnum' 这样：

data3$ft_newnum <- factor(data3$ft_newnum, 
         levels = c(2,3,4,5,6,7,9,11,12, 13, 14, 15), 
         labels = c("Donald Trump", "Christian fundamentalists", "Elites", 'Republicans', 'Denison Republicans', 'Denison Greeks', 'Denison Varsity Athlete','Hillary Clinton', 'Denison Democrats', 'Democrats', 'Bernie Sanders', 'Weinberg'))

然后编辑代码将这一变化：

data3 %>% 
    mutate(ftFct = fct_rev(as.factor(ft_newnum))) %>% 
    ggplot(aes(y = ftFct)) + 
    geom_density_ridges(aes(x = ft, fill = paste(ftFct, rep)), 
         alpha = .8, color = "white", from = 0, to = 100) + 
    labs(x = "Feeling Themometer Responses (%)", 
     y = " ", 
     title = "Republican vs Democratic Views Towards...", 
     subtitle = "Analysis unit: students (n = 595)") + 
    scale_y_discrete(expand = c(0.01, 0)) + 
    scale_x_continuous(expand = c(0.01, 0)) + 
    scale_fill_cyclical(breaks = c("Donald Trump 0", "Donald Trump 1"), 
         labels = c(`Donald Trump 0` = "Democrat", `Donald Trump 1` = "Republican"), 
         values = c("#8080ff", "#ff8080", "#0000ff", "#ff0000"), 
         name = "Political Affiliation", guide = "legend") + 
    theme_ridges(grid = FALSE)

这码图图中：

这几乎完美，但问题是，光线和暗色之间的交替关闭。前两行是深色的，后面是两条浅色的行。我需要保留标签，但也要保持准确的周期性交替，如第一张图所示。

任何想法？谢谢！

回答：

啊，我想通了。而不是覆盖'ft_newnum'变量，创建一个新变量（ft_newnum2）。

data3$ft_newnum2 <- factor(data3$ft_newnum, 
         levels = c(2,3,4,5,6,7,9,11,12, 13, 14, 15), 
         labels = c("Donald Trump", "Christian fundamentalists", "Elites", 'Republicans', 'Denison Republicans', 'Denison Greeks', 'Denison Varsity Athlete','Hillary Clinton', 'Denison Democrats', 'Democrats', 'Bernie Sanders', 'Weinberg'))

ft_num2用于设置y轴，而原始ft_num保持并用于填充绘图。

data3 %>% 
    mutate(ftFct = fct_rev(as.factor(ft_newnum2))) %>% 
    ggplot(aes(y = ftFct)) + 
    geom_density_ridges(aes(x = ft, fill = paste(ft_newnum, rep)), 
         alpha = .8, color = "white", from = 0, to = 100) + 
    labs(x = "Feeling Themometer Responses (%)", 
     y = " ", 
     title = "Republican vs Democratic Views Towards...", 
     subtitle = "Analysis unit: students (n = 595)") + 
    scale_y_discrete(expand = c(0.01, 0)) + 
    scale_x_continuous(expand = c(0.01, 0)) + 
    scale_fill_cyclical(breaks = c("2 0", "2 1"), 
         labels = c(`Donald Trump 0` = "Democrat", `Donald Trump 1` = "Republican"), 
         values = c("#8080ff", "#ff8080", "#0000ff", "#ff0000"), 
         name = "Political Affiliation", guide = "legend") + 
    theme_ridges(grid = FALSE) + 
    theme(legend.position="bottom")
