Hi Jesse,
Here is another option by using a function, which argument is the file's
name:
# A function
rmf<-function(filename){
x<-readLines(filename,warn=FALSE)
res<-which(x=='data table' | x=='end table')
x<-x[seq(res[1]+1,res[2]-1)]
mydata<-read.table(textConnection(x))
closeAllConnections()
mydata
}
As you see, I used some ideas from Jim Holtman's post (I hope you don't mind
Jim). Here is how 'rmf' works:
> rmf('ex.txt') # I saved the data you sent as 'ex.txt' keeping the same
structure
V1
1 1000
2 10110
3 11
Now, if you have a lot of files with the same structure and you want to
extract the same information, then using *apply you will be able to do the
job. All you need is the name of them.
HTH,
Jorge
