How to display text with Quotes in R? [duplicate]

Answer 1

Use a backslash :

x <- "say \"Hello!\""

And you don't need to use c if you don't build a vector.

If you want to output quotes unescaped, you may need to use cat instead of print :

R> cat(x)
say "Hello!"

Answer 2

Other answers nicely show how to deal with double quotes in your character strings when you create a vector, which was indeed the last thing you asked in your question. But given that you also mentioned display and output, you might want to keep dQuote in mind. It's useful if you want to surround each element of a character vector with double quotes, particularly if you don't have a specific need or desire to store the quotes in the actual character vector itself.

# default is to use "fancy quotes"
text <- c("check")
message(dQuote(text))
## “check”

# switch to straight quotes by setting an option
options(useFancyQuotes = FALSE)
message(dQuote(text))
## "check"

# assign result to create a vector of quoted character strings
text.quoted <- dQuote(text)
message(text.quoted)
## "check"

For what it's worth, the sQuote function does the same thing with single quotes.

Answer 3

As @juba mentioned, one way is directly escaping the quotes.

Another way is to use single quotes around your character expression that has double quotes in it.

> x <- 'say "Hello!"'
> x
[1] "say \"Hello!\""
> cat(x)
say "Hello!"
