Hello all,
I'm a new user of R, experienced with Octave/MATLAB and therefore
struggling a bit with the new syntax.
One of the easy things in Octave or MATLAB is to plot multiple lines or
sets of points by using a matrix where either the columns or the rows
contain the y-values to be plotted. Both packages automatically give
each line/points their own unique colour, character etc.
I'm wondering how I get the same functionality in R. For example, if X
is a vector of x-values and Y is a matrix whose rows contain the
y-values, I can do,
apply(Y,1,lines,x=X)
... but of course everything is all in black, with the same type of line
or points. I'd like each line to have its own unique colour and/or style.
Another thing I'd like clarification on is the ability to update an
existing plot. For example if I do,
plot.window(xlim=c(0,100),ylim=c(0,1))
and then after plotting data decide I want ylim=c(0,0.5), how do I
update the graphic? A new plot.window() command does nothing.
Many thanks,
-- Joe
