[R] problems with read.table

Dear R users,
I have the following problem:
I have a table in ASCII-format, separated with commas. I can read it as
long as no field contains a comma itself. If one does, read.table doesn't
function even though that field is double-quoted.


File "test.csv":

Jsaac,Gossauerstrassee 29,9100
Roth-Bernasconi,"20, ch. des Fauvettes",1212

adressen <- read.table("test.csv", header=T, sep=",")

results in an error as the comma in "20, ch. des Fauvettes" is interpreted
as a field delimiter. Playing around with read.table and also with scan I
found out that double-quotes are always interpreted as characters of their

What can I do? Thanks for any help.
