R help - Apr 2010 - Using read.table to read file created with read.table and qmethod = "escape"

df <- data.frame(a = "a\"b")
write.table(df, "test.csv", sep = ",", row = F)

Is there any to load test.csv into R correctly?  I've tried the following:
> read.table("test.csv", sep = ",")
[1] V1
<0 rows> (or 0-length row.names)
Warning message:
In read.table("test.csv", sep = ",") :
  incomplete final line found by readTableHeader on
'test.csv'
> read.table("test.csv", sep = ",", allowEscapes = T)
[1] V1
<0 rows> (or 0-length row.names)
Warning message:
In read.table("test.csv", sep = ",", allowEscapes = T) :
  incomplete final line found by readTableHeader on 'test.csv'

And I can't see any other options in read.table that would apply.

Regards,

Hadley

This worked for me in R 2.11.0 alpha:

df <- data.frame(a = "a\"b", v = 4, z = "this is Z")
write.csv(df, "test.csv", row.names = FALSE, quote = FALSE)
read.csv("test.csv", quote = "")
