R help - Dec 2005 - 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)
        The following object(s) are masked from ovendata ( position 3 ) :

         D Eight Five Four One Seven Three Two 


        The following object(s) are masked from ovendata ( position 4 ) :

         D Eight Five Four One Seven Three Two 


        The following object(s) are masked from ovendata ( position 5 ) :

         Eight Five Four One Seven Three Two 


        The following object(s) are masked from package:stats :

         D 
> print(ovendata)
     D One Two Three Four Five Seven Eight
1 1130 254 252   375  384  252   375   876
2  127 250 250   384  386  251   378   875

Eric

I see no error here, let alone an error in read.table as claimed in your 
subject line.

The posting guide does specifically ask `Use an informative subject line'.

Please distinguish warnings about _your_ usage from errors in R.

The first warning is that R fixed up an error in your file: it is missing 
a newline at the end of the last line (we can't see that in your listing).

The remaining warnings come from attach() and say you have already 
repeatedly attach()ed ovendata.  Learn to use detach() to match attach().
Also, in attaching ovendata you mask the function D in package stats, 
which is probably OK as you are not using it, and your D is a not a 
function.
