R help - Jul 2005 - error with scan

Hi:

I am trying to read a large (500000+ lines) with scan() as read.table  
is unable to read it.

I get a strange error (below) which says that 'a real' was expected  
and '5' was read. Can someone help?

Thanks,
jp

 > type=list(a=0,b=0,c=0,d=0,e=0,f="",g=0,h=0,i=0)
 > tmp2 <- scan(file="tmp2.txt", what=type, sep=",",
quote="\"",
dec=".", skip=1, nmax=541502)
Erreur dans scan(file = "tmp2.txt", what = type, sep = ",",
quote =
"\"",  :
     scan() attendait 'a real' et a re??u '5'

Can you show us the first line of the file?

The error means that in one of the values you specified as numeric (first,
second, third, fourth, fifth, seventh, eighth, ninth), it found the character
value it displayed.

Otherwise, this looks like a good use of scan.
