Hello,
Here is a link to some data:
http://www.epa.gov/emap/html/data/surfwatr/data/mastreams/9396/wchem/chmval.txt
I am trying to read this in, and want to use:
chmval <-
read.table("http://www.epa.gov/emap/html/data/surfwatr/data/mastreams/9396/wchem/chmval.txt";,
sep=",", skip= 84, header=T)
the # 84, for 84 lines skipped needs to be derived from the 5th line of the
txt file
# Header Records: 85
so, I need that # (-1) for input into the read.table statement above
I've tried grep but that didn't work:
(for this I downloaded the txt file and manually removed that hash mark!)
grep("Header Records:", read.table("chmval.txt", header=T))
Error in scan(file, what, nmax, sep, dec, quote, skip, nlines, na.strings,
:
line 1 did not have 5 elements
Any ideas?
Can I just extract the 5th line?
