R-beta: Read_Table?

[Kryp33]

Hello All !
Can anybody help me with simple question, please? I have tried to input some
data to R and I use the read.table function. The exactly form that I type was:

>  test1 <- read.table("D:\Rstat\Work\Abt.data",header=T,sep=",")

I've got the response from R:

Error: "scan" can't open file

The file that I specify above "Abt.data" is a standard ASCII table file with
names of fields in the first line and data below. The beginning of the file
looks like:

"Open","High","Low","Close","Volume"
29.500,29.750,28.625,28.875,1269000
28.875,29.750,28.625,29.500,977300
29.750,30.625,29.625,30.125,2894100

I am new to R-program. It seems that I've done very simple mistake in my first
attempts. Please, help me with that or give me any  references where I can get
the answer. I use Windows 95 OS and follow instruction in "Notes on R" by Bill
Venables & Dave Smith.
Thanks a lot!
Sergey
