The dQuote() function in R is used to add double quotes around a string.
This function is specifically helpful when you need to present strings in a formatted way, such as in printed output or in constructing messages and plots.
Syntax
dQuote(x)Parameters
x: It is a string or character vector.
Return value
It returns a character vector with double quotes around each element.
Example 1: Basic usage
string <- "Expelli Armus"
dQuote(string)Output
[1] "“Expelli Armus”"Example 2: Pass integer as a string
expression <- "1 + 2 / 2 * 4"
dQuote(expression)Output
[1] "“1 + 2 / 2 * 4”"For single quotes, use the sQuote() function, which works similarly.
