search for: textline

...ven possible to do it that way using the (.)a command? Thanks in advance Thomas code example that give a "no match". Fairly easy to read and understand example 1: ----------- for RFILE in $RLIST; do ed - RFILE <<- EOF H /\[matching_text_1\]/a This is the appended textline(s) for text1 . /\[matching_text_2\]/a This is the appended textline(s) for text2 . w q EOF done Another example that solve the above problem. But this example become very easy unreadable if the appended text is long and/or includes linebreaks. Example 2: ----------...

Dear R-help, This one is probably a piece of cake for regexp masters. I'd like to split a character vector (for simplicity, say of length one for now) that contains fields that are delimited by arbitrary number of white spaces (e.g., " a b c "). How do I get the character vector that contain the fields? In the example I gave, I've tried: > strsplit(" a b c

Hi I could only find some discussion on this wrt lattice graphics (which I'm not using). Apologies if I'm missing something obvious. I'd like to produce 3 rug plots under a kernel density plot for a population. The population is subdivided into 3 subpopulations, which I'd like the rug plots to highlight. Naturally, when I do 3 rug plots, they all plot over each other.

Trying to use R to build an interactive "slide show", to be displayed on a projector. The purpose of the presentation is to show how one could construct a simple graph using R. It is meant as a general overview rather than as detailed instruction. For example, something like the following sequence of commands. At lecture time, I want the interpreter to read these commands one at a
