read.table error

Hey, Once again I ask for some quick help.

Here is some code:
ovendata<- read.table("ovens.dat",header=TRUE)
attach(ovendata)
print(ovendata)

Here is the .dat file:
D    One     Two     Three   Four    Five    Seven   Eight
1130    254     252     375     384     252     375     876
127     250     250     384     386     251     378     875

Here is the R Console output:

ovendata<- read.table("ovens.dat",header=TRUE)

Warning message:
incomplete final line found by readTableHeader on 'ovens.dat'

attach(ovendata)

D One Two Three Four Five Seven Eight

2  127 250 250   384  386  251   378   875

I've never seen anything like theis before. What's going on?
