R help - Apr 2012 - Reading first line before using read.table()

So far I have figured out that the following line 
reads our time series files into R OK. 
dtLs$dta <- read.table("C:/TryRRead/datFiles/JFeqfi4h.rta", header
= TRUE,
sep = ",", colClasses = "character")
But I have to remove a main-title line so 
that the first line is the column titles line.
This leads to having two sets of data files around when 
we would rather have just one set. 
How can I read just one line from the file to
get the main title in before using the read.table() call?

Not sure I understand correctly, but would something like this do?

R> title.line <- readLines('file.rta', n=1)
R> dat <- read.table('file.rta', skip=1, header=TRUE, ...)

Thanks so much. The following are the actual lines I used for testing, and
they worked. 

 titleline <- readLines("C:/ad/dta/TryRRead/pureCos2.dta", n=1) 
  print(titleline) 
  dta <- read.table("C:/ad/dta/TryRRead/pureCos2.dta", skip = 1,
header TRUE, sep = ",", colClasses = "character")
  linDta <- linearizeTime(dta); 
#  plot(linDta) 
  spec.pgram(dta[2],log="no",taper=0,xlim=c(0,.05))
