Re: [R] GREP - Choosing values between two borders

Another way you can do it, if the data has the pattern shown in your sample, it to select all the lines that start with a numeric: input - FILE-CONTENT ## + EXAM NUM:2 + - + EXAM #1 + ASTIG:-2.4D + AXIS:4.8 + START OF HEIGHT DATA + 0 0.0 0. + 0 0.1

[R] GREP - Choosing values between two borders

Hello, I import datas from an file with: readLines But I need only a part of all measurments of this file. These are between two borders START and END. Can you tell me the syntax of grep(), to choose values between two borders? My R Code was not succesful, and I can't finde anything in the help.

Re: [R] grep question

You have to be careful if the strings are embedded: x - c('xxxFarrahxxx' ,'more than last time', 'some Common numbers', 'last one') setdiff(x, grep('Farrah|Common', x)) # not correct [1] xxxFarrahxxxmore than last time some Common numbers last one ForC - grep('Farrah|Common', x)

Re: [R] grep question

Forget the last reply. I left the 'value=TRUE' off the grep. x - c('xxxFarrahxxx' ,'more than last time', 'some Common numbers', 'last one') setdiff(x, grep('Farrah|Common', x, value=TRUE)) [1] more than last time last one ForC - grep('Farrah|Common', x) x[setdiff(seq(along=x), ForC)] [1]

If all you need to do is extract the subset of elements of txt that do not contain 'foo', then txt[-i] will do the job. Provided that at east one element of txt contains 'foo', that is. -Don At 2:59 PM +0200 6/23/05, Marcus Leinweber wrote: hi, using the example in the grep help: txt -
