Question

我想在Windows上使用R软件包skim中的函数skimr。不幸的是，在许多情况下，hist列打印不正确（带有许多类似<U+2587>的符号），如下例所示。

问题：是否有一种简单的方法可以禁用“ hist”列并阻止其打印或完全禁止计算？是否有类似hist = FALSE的选项？

capture.output(skimr::skim(iris))

将语言环境更改为中文（如this answer）不能解决问题，但会使情况更糟：

Sys.setlocale(locale = "Lithuanian")
df <- data.frame(x = 1:5, y = c("Ą", "Č", "Ę", "ū", "ž"))

Sys.setlocale(locale = "Chinese")
capture.output(skimr::skim(df))

#> Error in substr(names(x), 1, options$formats$.levels$max_char) : invalid multibyte string at '<c0>'

Answer 1

skim_with(numeric = list(hist = NULL))在“使用Skimr”小插图中。

Answer 2

您也可以使用skim_without_charts代替skim。
