Regex for Special Characters under Grep
Hi all,
I am trying to capture lines of a file that DO NOT
start with the following header: !, #, ^
But somehow my regex used under grep doesn't
work.
Please advice what's wrong with my code below.
__BEGIN__
in_fname <- paste("mydata.txt,".soft",sep="")
data_for_R <- paste("data_for_R/", args[3], ".softR", sep="")
# my regex construction
cat(temp[-grep("^[\^\!\#]",temp,perl=TRUE)], file=data_for_R, sep="\n")
dat <- read.table(data_for_R)
___END__

Help with subset
...nt. The "x116" line has the merge
field, in this case "Bases-K Ammonium Acetate-2008-116". This changes for
each soil sample, and for each type of analysis. ##

Documents/R_Statistics/NAPT/NAPT_09/CertIn2010/Data_for_R/readin_all_for_2010_cert.csv
