Question

尝试在R中创建散点图时，我收到错误消息。当使用相同的数据集和相同的代码时，我的教授没有收到此错误消息。我重新安装了R，RStudio和所有R软件包但没有成功。情节看起来很好，所以我不明白为什么会抛出这些错误。

由于我正在使用RMarkdown（不在此特定代码段中，但我想将此图包含在RMarkdown文件中），因此错误消息会与图形一起出现在RMarkdown输出中，我想删除这些错误消息从输出中看起来很干净。

数据集取自https://wps.pearsoned.co.uk/wps/media/objects/12401/12699039/datasets3e/datasets/caschool.xlsx。

我将不胜感激任何暗示（1）抑制警告信息，因为情节实际上看起来很好（2）或解决潜在的问题。当然，选项（2）更可取。

library(readxl)
caschool <- read_excel("../dataStockWatson15/caschool.xlsx")

library(car)
scatterplot(testscr~str, reg.line=FALSE, smooth=FALSE, spread=FALSE, boxplots=FALSE, span=0.5, ellipse=FALSE, levels=c(.5, .9), data=caschool)
warnings()

警告：

警告似乎是在汽车套件的最新版本中创建的，我认为你正在运行。至少，在将软件包从版本2.1.6更新到版本3.0.0之后，并添加了软件包openxlsx_4.0.17和rio_0.5.10之后，我可以复制警告。

如果没有简单地忽略警告，那么解决方案似乎就是安装汽车包2.1.6版。您可以在此处下载源代码：https://cran.r-project.org/src/contrib/Archive/car/。
