从R脚本在excel中打开CSV文件

Question

I have generated a csv file in R and would like my script to open this file in excel so that someone with no knowledge of R can modify the data. (Ideally when I run the script excel opens and loads this file). What is the best way to accomplish this?

Answer 1

The cmd command to open an excel file is open excel file.xlsx . In R you can run the command line using system . So putting these together:

excel_file_with_path <- "C:/Users/myusername/Documents/file.xlsx"
command <- paste("open excel", excel_file_with_path)
system(command)

Answer 2

The accepted answer does not work for me, although not sure why (Windows OS), and I keep having to search for this answer again and again- so here is the answer that works for future reference.

shell.exec(here::here("filename.csv"))

This should open any file with the default program. credit: answer lifted directly from Uwe Ligges outside of SO

(note: my use of the here::here() function is just an easy way to create a complete filepath, referenced to your RStudio project directory)
