我正在观察 R 的一个非常奇怪的行为。
当我将以下代码逐行键入到从终端运行的 R 实例中时，以下代码将起作用。（操作系统是 Debian Linux。）
但是，当我尝试运行时它不起作用source("script.R")。
它也不能在 R Studio 中工作。
具体来说，它无法生成带有autoplot. 写入 pdf 文件不起作用，如果我删除pdf()和dev.off()行，则不会打开包含该图形的窗口。
这是我的脚本的副本...
library(lubridate)
library(ggplot2)
library(matrixStats)
library(forecast)
df_input <- read.csv("postprocessed.csv")
x <- df_input$time
y <- df_input$value
df <- data.frame(x, y)
x <- df$x
y <- df$y
holtmodel <- holt(y)
pdf("autoplot.pdf")
autoplot(holtmodel)
dev.off()
为方便起见，这里有一个数据文件。

很困惑，因为它看起来像一个微不足道的脚本！
