I discovered that it doesn't work when the pattern "...." is not on one
line.
Here's an example of file read with readLines :
Lines <- c("line one example",
"line two example",
"example \"comment on one line it works \" end of the line",
"example \" comment on two lines",
"the end of the comment \" without ' inside",
"example \" comment on one line with ' inside it works \" end of the line",
"example \" comment on two lines with '",
"inside it doesn't works \"")
s <- Lines
f <- function(x) chartr(paste(squote, dquote), paste(dquote, squote), x)
gsubfn('["][^"]*["]', f, s)
[1] "line one
example"
[2] "line two
example"
[3] "example 'comment on one line it works ' end of the
line"
[4] "example \" comment on two
lines"
[5] "the end of the comment \" without '
inside"
[6] "example ' comment on one line with \" inside it works ' end of the
line"
[7] "example \" comment on two lines with
'"
[8] "inside it doesn't works \""
