linux - 如何在 Linux 上提交 R 作业？

Question

我是 R 的工程师新手，有一个必须在 Linux 上运行的脚本，我搜索了很多但无法找到在 Linux 上运行该脚本的简单命令。我必须将我的工程软件与 R 相结合，因此我还需要在 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。

最好的问候。

Answer 1

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”扩展名命名这些脚本，但我不确定是否有必要。

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
"2",0.37212389963679,0.944675268605351,0.176556752528995,0.717618508264422
"3",0.572853363351896,0.660797792486846,0.687022846657783,0.991906094830483
"4",0.908207789994776,0.62911404389888,0.384103718213737,0.380035179434344
"5",0.201681931037456,0.0617862704675645,0.769841419998556,0.777445221319795

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。
