ggplot order by discrete mean by y？

我的數據看起來是這樣的：ggplot order by discrete mean by y？

df1 <- structure(list(truth = structure(c(1L, 60L, 60L, 1L, 60L, 1L, 
              51L, 60L, 1L, 51L, 51L, 51L, 1L, 60L, 1L, 1L, 1L, 1L, 51L, 51L, 
              60L, 1L, 51L, 60L, 60L, 51L, 1L, 51L, 51L, 60L, 1L, 51L, 60L, 
              60L, 60L, 60L, 51L, 51L, 1L, 51L, 60L, 60L, 51L, 60L, 51L, 1L, 
              60L, 60L, 1L, 51L), .Label = c("1", "2", "3", "4", "5", "6",

                     112L, 8L), class = "data.frame")

我想產生這樣

df1 %>% ggplot(aes(x=truth, y=Value)) + 
    stat_summary(fun.data=mean_cl_boot, mult=1, 
       geom="pointrange", conf.int=0.95) + 
    theme_bw()

一個情節，我要重新排序「真相」 acording爲每一個平均值。在這個例子中，1,60,51。

我該怎麼做？

謝謝！

見http://stackoverflow.com/questions/5738619/ggplot2-possible-to-reorder-xs-by-value-of-computed-y-stat-summary – bergant

您可以重這樣

ggplot(data = df1, aes(reorder(truth, truth),Value)) + 
stat_summary(fun.data=mean_cl_boot, mult=1, 
geom="pointrange", conf.int=0.95) + 
theme_bw()

編輯

如果要重新排序基於值列，然後做這個

ggplot(data = df1, aes(reorder(truth, Value),Value)) + 
stat_summary(fun.data=mean_cl_boot, mult=1, 
geom="pointrange", conf.int=0.95) + 
theme_bw()

而且如果您想要的任何情況下根據價值列的降序重新排序，你可以這樣做:)

ggplot(data = df1, aes(reorder(truth, -Value),Value))

我嘗試運行，而不是使任何區別:( – Ignacio

是的。我認爲Veerandra有一個錯字。它應該是aes（reorder（真相，價值），價值） – Ignacio
