Subject: [R] Read text file
How do I read a block of space-delimited numbers into a column vector
using the read.table command? Thank you.

I am not sure what you mean by "a block", but you can probably use
scan() instead of read.table():
> txt <- "1 21 41 61 81"
> d <- data.frame(Numbers=scan(text=txt, what="numeric", quiet=TRUE))
> d
Numbers
1 1
2 21
3 41
4 61
5 81

Hi,
There is no GPGLL or GPGLA entries in the data. You can use ?grep to read
those lines.
##Modifying the input data

Since you don't have a header on the first line, just use 'read.table'.

Hello,
See the "fill" option of the "read.csv" function. But be careful, it
might lead to erroneous results, as explained in the help page...
And there is neither $GPGLL nor $GPGLA in your example.
Regards,
Pascal

Chuck,
Thanks so much, these both work like a charm. The first method, though,
is very, very slow for a large dataset (<100,000) while the second is
reasonable in terms of speed. If you or anyone have any ideas for
speeding up the import send them my way otherwise the:

Hi All,
Can anyone direct me to a read function in R that will allow me to only
read in rows of a text file that begin with a particular value such as
