我是 R 的工程师新手,并且有一个必须在 linux 上运行的脚本,我进行了很多搜索,但找不到在 linux 上运行脚本的简单命令。我必须将我的工程软件与 R 结合起来,所以我也需要在 linux 上运行它。
My script name is myscipt.R and I want to use 2 cpus to run that script.
请帮助我启动。
最好的祝福。

这对我有用:
R CMD BATCH myscript.R
例如,以下应生成随机生成矩阵的 .csv 文件。我一直用“.R”扩展名来命名这个脚本,但我不确定这是必要的。
要调用的脚本(名为“testscript.R”)包含以下代码行:
set.seed(1)
M<-matrix(runif(20),5,4)
write.csv(M, file="M.csv")
然后在您的控制台中调用此脚本,如上图所示:
R CMD BATCH testscript.R
在我的机器上,这会生成“M.csv”文档,如下所示:
"","V1","V2","V3","V4"
"1",0.2655086631421,0.898389684967697,0.205974574899301,0.497699242085218

此外,还会生成一个“testscript.Rout”文件,提供 R 控制台输出:

希望能更好地解释它。
