comma within paste in R

问题

I would like to paste something that has "" within.

> i = 4
> paste("var", i, "option="juk"", "--opt2 12")

Error: unexpected symbol in "paste("var", i, "option="juk"

What the pasted phrase should look like (which included comma within)

var 4 option = "juk" --opt2 12

Is there any way to solve this ?

回答1:

One option would be

(x <- paste("var", i, 'option="juk"', "--opt2 12"))
# [1] "var 4 option=\"juk\" --opt2 12"
cat(x)
# var 4 option="juk" --opt2 12
