无论我做什么尝试,都无法使用ggridges
创建山脊线图。使用如下所示的数据帧graphing_dataframe
:
str(graphing_dataframe)
summary(graphing_dataframe)
> str(graphing_dataframe)
Classes ‘tbl_df’, ‘tbl’ and 'data.frame': 14 obs. of 3 variables:
$ id : chr "00343" "00343" "00343" "00343" ...
$ week : num 14 1 2 3 4 5 6 7 8 9 ...
$ rating: num 14 4 12 8 14 19 16 16 7 8 ...
- attr(*, "spec")=
.. cols(
.. id = col_character(),
.. week = col_double(),
.. rating = col_double()
.. )
> summary(graphing_dataframe)
id week rating
Length:14 Min. : 1.00 Min. : 4.00
Class :character 1st Qu.: 4.25 1st Qu.: 8.00
Mode :character Median : 7.50 Median :10.50
Mean : 7.50 Mean :11.43
3rd Qu.:10.75 3rd Qu.:15.50
Max. :14.00 Max. :19.00
我的数据是
structure(list(id = c("00343", "00343", "00343", "00343", "00343",
"00343", "00343", "00343", "00343", "00343", "00343", "00343",
"00343", "00343"), week = c(14, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10,
11, 12, 13), rating = c(14, 4, 12, 8, 14, 19, 16, 16, 7, 8, 9,
18, 9, 6)), class = c("tbl_df", "tbl", "data.frame"), row.names = c(NA,
-14L), spec = structure(list(cols = list(id = structure(list(), class = c("collector_character",
"collector")), week = structure(list(), class = c("collector_double",
"collector")), rating = structure(list(), class = c("collector_double",
"collector"))), default = structure(list(), class = c("collector_guess",
"collector"))), class = "col_spec"))
我的代码是
ggplot(graphing_dataframe,
aes(x = rating, y = week, fill = ..x..)
) +
geom_density_ridges()
Picking joint bandwidth of 2.53
Error: geom_density_ridges requires the following missing aesthetics: y
我已经尝试过每this question使用unlist
,但这也不起作用。

似乎错误消息有点让人误解,根据documentation,您需要为数字变量添加整体美感:
如果将分类变量映射到y轴,则不需要提供分组美观性,但是如果变量是数字,则必须提供分组美观性。
因此将group = week
添加到ggplot(aes(…))
应该可以解决问题。 (我自己也遇到过同样的问题。)
答案 1 :(得分:1)
正如@JonnyPhelps所说,我的数据与山脊线图不兼容(反之亦然)。
答案 2 :(得分:0)
在搜索该错误消息时,这个问题似乎在列表的顶部,所以我想听一听:出现此错误的另一个原因是,如果您有x
和{{ 1}}切换:
例如,使用上面的数据(改为使用y
),这有效:
id
这会引发错误:
ggplot(graphing_dataframe,
aes(x = rating, y = id)) +
geom_density_ridges()
答案 3 :(得分:0)
我还注意到,如果y是一个因素,则不会弹出此错误。 试试这个:)
ggplot(graphing_dataframe,
aes(x = id, y=as.factor(rating))) +
geom_density_ridges()
答案 4 :(得分:0)
在上述讨论和文档的启发下,我成功使用了这两种模型: ggplot(CSVdotcsv,aes(x = TSH,y = as.factor(t)))+ #as factor提供小时的图例 ggplot(CSVdotcsv,aes(x = TSH,y = t,group = t))+#重要的是添加group =
答案 5 :(得分:0)
y 需要是一个分类变量。你可以试试:
ggplot(graphing_dataframe,
aes(x = rating, y = as.factor(week), fill = ..x..))+
geom_density_ridges()
或
ggplot(graphing_dataframe,
aes(x = rating, y = as.character(week), fill = ..x..))+
geom_density_ridges()
