或者

这些看起来像是需要互动使用的文件（例如，在RStudio中打开它们），因为它们包含到文件的绝对链接（例如 read.table("c:/Work08/StatDesignSC08/Data/Alfalfa.txt", sep = "", header = TRUE)）。我建议您下载它们，然后打开。例如，使用以下命令：
source_file <- "http://archived.stat.ufl.edu/casella/StatDesign/WebRPrograms/Alfalfa.R"
download.file(url = source_file, destfile = basename(source_file))
file.edit(basename(source_file))
然后编辑您需要的路径。否则，您将不断遇到“无法打开文件”的错误。
英文:
These look like files that you need to use interactively (e.g., open them in RStudio) as they contain absolute links to files (e.g. read.table("c:/Work08/StatDesignSC08/Data/Alfalfa.txt",sep = "",header=T)). I would suggest you download them and then open them. For example using these commands:
source_file <- "http://archived.stat.ufl.edu/casella/StatDesign/WebRPrograms/Alfalfa.R"
download.file(url = source_file, destfile = basename(source_file))
file.edit(basename(source_file))
And then edit the paths you need. Otherwise you will constatntly run into cannot open file errors.

你可以使用devtools包中的source_url函数。
library(devtools)
source_url("http://archived.stat.ufl.edu/casella/StatDesign/WebRPrograms/FishTank.R")
请注意，在Windows上，这也应该有效：
source("http://archived.stat.ufl.edu/casella/StatDesign/WebRPrograms/FishTank.R")
英文:
You can use the function source_url from devtools package.
library(devtools)
source_url("http://archived.stat.ufl.edu/casella/StatDesign/WebRPrograms/FishTank.R")
Please note that on windows this should also work:
source("http://archived.stat.ufl.edu/casella/StatDesign/WebRPrograms/FishTank.R")
