What bugs me is that I think it would import fine if the folks who created the csv had used double quotes "" rather than an escaped quote \" for those pesky internal quotes. Since that's the case, I'd think there would be a solution within read.csv() ... or perhaps scan()?, I just can't figure it out.
What you say doesn't make sense. Let me paraphrase:
"The folks who sent me the data created a weird, non-standard .csv file.
You'd think read.csv() could handle it."
The standard way to handle quotes in strings is to double them. They
didn't, so you've got a weird file on your hands.
You can probably fix it by doing a global substitution of all "backslash
doublequote" pairs with "doublequote doublequote". Unless they have
some "backslash backslash doublequote" triples that they want you to
interpret as "backslash doublequote". Or some other weirdness.
I'd suggest you try the global subst mentioned above. or ask them for
data in a reasonably standardized format.
