R等待系统可执行文件完成

Question

我正在尝试通过位于我的C：/ GenSoftware / Colony /目录中的可执行文件Colony2.exe运行一系列输入文件（位于我的C：/ GenSoftware / Colony / datFiles /目录中）。我尝试重命名文件1，将其复制到与可执行文件相同的目录，使用包rcolony中的run.colony函数（粘贴在底部）运行Colony2.exe，删除文件，然后继续执行文件2。

但是，代码尝试在可执行文件完成之前继续。如何让我的循环等到Colony2.exe完成后再进入下一行代码，然后重新运行循环。 run.colony调用系统命令（粘贴在底部）。

到目前为止，这是我的代码......

rm(list=ls())

setwd("C:/GenSoftware/Colony/")
getwd()
datFiles <- list.files("datFiles")
library(rcolony)



d <- 0
for (d in 1:length(datFiles))
{
  d <- d+1
  setwd("C:/GenSoftware/Colony/datFiles/")
  file.rename(datFiles[d],"Colony2.DAT")
  file.copy(from = "C:/GenSoftware/Colony/datFiles/Colony2.DAT",to = "C:/GenSoftware/Colony/")
  datPath <- "C:/GenSoftware/Colony/Colony2.DAT"
  setwd("C:/GenSoftware/Colony/")
  run.colony(colonyexecpath = "Colony2.exe", datPath, wait = TRUE, monitor = FALSE)
  unlink(x = "C:/GenSoftware/Colony/Colony2.DAT", recursive = FALSE, force = TRUE)
  setwd("C:/GenSoftware/Colony/datFiles/")
  file.rename("Colony2.DAT",datFiles[d])
}

########我的代码结束，run.colony CODE开始

run.colony

    wait = FALSE, monitor = TRUE)

        flush.console()

    }
