Dear all,

I just started using R today. What I need to do is find a text string in a (large) text file and than copy the some position related lines (or text) to an other text file. Is this possible with R?

Example: Search string is: "Date"
write line of <search string> +0, +2, +6, +7, +8, +9

559 y1=1.9
560 x2=35
561 y2=870
..

etc

The new text file must contain:
########################################
Date: 01-10-03
Time: 17:52:23
x1=1.5
y1=2.9
x2=29
y2=704
Date: 01-10-03
Time: 18:04:11
x1=1.1
y1=1.9
x2=35
y2=870
etc
########################################

Is this possible??

Kind Regards, Gerard
