The lintr package has a check for single-quoted strings, and single quotes are discouraged elsewhere (e.g. ?Quotes). Single and double quoted strings work identically in R, so is there a reason why single quotes are considered bad practice?
Citations to canonical documents especially welcome. To be clear: I'm asking about the reasons given by the R core team for discouraging single quotes; not about people's own opinions on the topic.
I guess because R by default prints using double quotes. This way the 'other quote character' in a string gets
a) handled normally if its a single quote
b) escaped when its a double quote
when printing. Using double-quotes discourages the use of double-quotes in a string.
Take the following example:
Double Quoted
"It's my car"
Prints
"It's my car"
Single Quoted
'It"s my car'
Prints
"It\"s my car"
