Mik*_*ike 11 r hmisc dplyr tidyverse
我使用的是r 3.3.3,dplyr 0.7.4和Hmisc 4.1-1.我注意到我加载包的顺序会影响dplyr :: summaries函数是否有效.我知道以不同的顺序加载包会掩盖某些函数,但我使用package :: function()语法来避免这个问题.确切的问题围绕标记变量.我知道过去有过tidyverse和变量标签的问题,但似乎都没有解决为什么会出现这种特殊情况.
第一个有效的例子 - 我只加载Hmisc然后加载dplyr并且我能够汇总数据 -
#this works fine
library(Hmisc)
library(dplyr)
Hmisc::label(iris$Petal.Width) <- "Petal Width"
sumpct <- iris %>%
dplyr::group_by(Species) %>%
dplyr::summarise(med =median(Petal.Width),A40 = round(100*ecdf(Petal.Width)(.40),1),
A50 =round(100*ecdf(Petal.Width)(.50),1),
mns = mean(Petal.Width),
lowermean = mean(Petal.Width)-sd(Petal.Width),
lowermedian = median(Petal.Width) - sd(Petal.Width))

以下第二个例子打破.我启动一个新的会话并在Hmisc之后加载tidyverse并仍然使用package :: function()语法,但这会引发错误:
summarise_impl(.data,dots)出错:评估错误:
x且labels必须是同一类型.
第二个例子:
###restart session
#this example does not work
library(Hmisc)
library(tidyverse)
Hmisc::label(iris$Petal.Width) <- "Petal Width"
sumpct <- iris %>%
dplyr::group_by(Species) %>%
dplyr::summarise(med =median(Petal.Width),A40 = round(100*ecdf(Petal.Width)(.40),1),
A50 =round(100*ecdf(Petal.Width)(.50),1),
mns = mean(Petal.Width),
lowermean = mean(Petal.Width)-sd(Petal.Width),
lowermedian = median(Petal.Width) - sd(Petal.Width))

但是,第三个示例在我重新启动会话并在Hmisc之前加载tidyverse的情况下工作
第三个例子:
###switch order of loading packages and this works
library(tidyverse)
library(Hmisc)
Hmisc::label(iris$Petal.Width) <- "Petal Width"
sumpct <- iris %>%
dplyr::group_by(Species) %>%
dplyr::summarise(med =median(Petal.Width),A40 = round(100*ecdf(Petal.Width)(.40),1),
A50 =round(100*ecdf(Petal.Width)(.50),1),
mns = mean(Petal.Width),
lowermean = mean(Petal.Width)-sd(Petal.Width),
lowermedian = median(Petal.Width) - sd(Petal.Width))

所以我的问题是为什么我在使用package :: function()语法专门针对标记变量和tidyverse时加载包的顺序很重要?

更新:从避风港版本2.0.0开始,这个问题已经解决,因为避风港"标记"类被重命名"haven_labelled"为避免与Hmisc冲突.
tl;博士:订单很重要.
有关更详细的答案,让我们首先重现错误:

从原始summarise示例中逐个删除元素后,我设法将错误重现到这些代码行:
Hmisc::label(iris$Petal.Width) <- "Petal Width"
head(iris)
#> Error: `x` and `labels` must be same type
Run Code Online (Sandbox Code Playgroud)
我们可以查看回溯以查看是否可以找到可能导致错误的函数:
traceback()
#> 8: stop("`x` and `labels` must be same type", call. = FALSE)
#> 7: labelled(NextMethod(), attr(x, "labels"))
#> 6: `[.labelled`(xj, i)

该[.labelled调用看起来可疑.为什么甚至被称为?

啊,为Petal.Widthwith 设置标签Hmisc::label也添加了S3类.我们可以检查定义方法的位置getAnywhere:
getAnywhere("[.labelled")
#> 2 differing objects matching '[.labelled' were found
#> in the following places
#> registered S3 method for [ from namespace haven
#> namespace:Hmisc
#> namespace:haven
#> Use [] to view one of them
Run Code Online (Sandbox Code Playgroud)
的确,haven和Hmisc定义方法.并且由于haven之后加载Hmisc,它的定义首先被找到,因此被使用:
getAnywhere("[.labelled")[1]
#> function (x, ...)
#> {
#> labelled(NextMethod(), attr(x, "labels"))
#> }
#> <environment: namespace:haven>
Run Code Online (Sandbox Code Playgroud)
haven期望labelled对象具有不创建的labels属性
Hmisc::label:
attr(iris$Petal.Width, "labels")
#> NULL
Run Code Online (Sandbox Code Playgroud)
这就是错误的来源.
haven甚至装?它不附带library(tidyverse).后来发现,这haven被列为导入的包中tidyverse,这会导致当包装被安装它被加载(参见例如
在此).除了其他方面,加载包还会注册其S3方法:这是冲突的来源.
正因为如此,如果你想同时使用Hmisc和tidyverse,订购事宜.为了解决这个问题,可能还需要在程序包使用labelledS3类时进行源代码级别的更改.
