In that case it simplifies to the following (same as before except
for definition of f):
library(gsubfn)
squote <- "'" # single quote. This is a double quote, single quote, double quote
dquote <- '"' # double quote This is a single quote, double quote, single quote
s <- "[\"...\" \"...'...\"]"
f <- function(x) chartr(paste(squote, dquote), paste(dquote, squote), x)
gsubfn('["][^"]*["]', f, s) # "['...' '...\"...']"
