【问题描述】:
我正在尝试根据频率制作一个带有有序条形图的图表,并且还使用一个变量,两个独立的两个变量使用构面。 单词必须按 'n' 变量中给出的值排序。 所以,我的图表应该看起来像 this one,它出现在 tidytext book 中:
我的图表如下,单词没有按值排序,我的错误是什么?: 我的数据看起来像示例中的数据:
> d
# A tibble: 20 x 3
word u_c n
<chr> <chr> <dbl>
1 apples candidate 0.567
2 apples user 0.274
3 melon user 0.191
4 curcuma candidate 0.105
5 banana user 0.0914
6 kiwi candidate 0.0565
...
按照书中提供的代码,根据我的数据进行修改,代码如下:
d %>%
mutate(word = reorder(word, n)) %>%
ggplot(aes(word, n, fill = u_c)) +
geom_col(show.legend = F) +
facet_wrap(~u_c, scales = "free_y") +
coord_flip()
这是dput 的d:
d <- structure(list(word = c("apples", "apples", "melon", "curcuma",
"banana", "kiwi", "grape", "curcuma", "grape",
"wood", "satsuma", "melon", "raisin", "papaya", "plum",
"plum", "papaya", "banana", "satsuma", "peach"), u_c = c("candidate",
"user", "user", "candidate", "user", "candidate", "user", "user",
"candidate", "user", "user", "candidate", "user", "candidate",
"candidate", "user", "user", "candidate", "candidate", "candidate"
), n = c(0.56704584625991, 0.273789875549109, 0.190633674260422,

这实际上是一个问题:github.com/tidyverse/ggplot2/issues/1902,但已由 David Robinson 解决:github.com/dgrtwo/drlib/blob/master/R/reorder_within.R

感谢您的信息,但我无法理解接下来的步骤,正如@Cpak 提到的那样,这个解决方案有点“神奇”^ ^。
