如何在linux上提交R作业？

Question

我是R的工程师新手并且有一个我必须在linux上运行的脚本，我搜索了很多，但是无法找到一个简单的命令来在linux上运行脚本。 我必须将我的工程软件与R耦合，所以我需要在linux上运行它。

My script name is  myscipt.R and I want to use 2 cpus to run that script.

请帮助我创业。

最好的祝福。

这对我有用：

R CMD BATCH myscript.R

例如，以下内容应生成随机生成矩阵的.csv文件。 我总是用“.R”扩展名命名这个脚本，但我不确定这是否有必要。

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
"2",0.37212389963679,0.944675268605351,0.176556752528995,0.717618508264422

"4",0.908207789994776,0.62911404389888,0.384103718213737,0.380035179434344

此外，生成“testscript.Rout”文件，给出R控制台输出：

希望能更好地解释它。
