Hi
If the file is tab delimited you could try something like this:
a<-read.delim(file, skip = 9, header=F, na.strings=NA)
Are you sure you want to skip 10 lines? (Is there a blank line
somewhere?)

R-help,
I have the following file I want to import to R (some lines
removed)
Calibrated CTD data for station:00280001
Calibrated:23/8 2001, Salinity Unsmoothed, Fluorescence Uncalibrated
Maximum observed depth: 36 m
QUAL has one digit for each of pressure, temp., sal. and fluor.
QUAL=1:Uncal., QUAL=2:OK, QUAL=6:Interp., QUAL=9:No data
DEPTH CTDPRS CTDTMP CTDSAL RAWFLU NUMB. QUAL
M DBAR IPTS-68 PSS-78 OBS.
******* ******* ******* *******

9 9.1 5.9792 35.1629 .113 11 2221

If I use :
read.table(file, skip = 10)
it works fine but sometimes the missing data are not only
in line number 1 ( 1 1.0 2999)
but in lines 1,2,3,,, and therefore R fails to import the data file
How can I fix it?
I have tried with the arguments
strip.white = TRUE
, fill = TRUE
, blank.lines.skip = TRUE
but still not get what I want
Thanks in advance
