Answer 1

尝试这个：

date<-as.character(Sys.Date())
  write.csv(dummy_opp, file = paste0("//ant/dept-as/XYZ2-User/Mega_data/File Management/SOA/Assignment-",date,"/Workbook.csv"),row.names = FALSE)

file将会：

"//ant/dept-as/XYZ2-User/Mega_data/File Management/SOA/Assignment-2018-02-19/Workbook.csv"

或者，如果您想要更紧凑的代码：

  write.csv(dummy_opp, file = paste0("//ant/dept-as/XYZ2-User/Mega_data/File Management/SOA/Assignment-",Sys.Date(),"/Workbook.csv"),row.names = FALSE)
