symbol in the plot

a graph question. Thanks a lot in advance.

I made two scatterplots on one graph (sigma vs. delta1, sigma vs. delta2)
(20 observations of delta1, delta2 and corresponding sigma) the x-axis is
sigma, the y-axis is either delta1 or delta2. I connected both
scatterplots. To seperate them, one curves is a line with circles, the
other curve is a line with squares on it. 

I want to make a notation either on the y-axis or on the graph. The
notiaion is "delta1--square; delta2--circle". So when people look at the
graph, they can easily tell each curve's meaning. The curve with squares
on it means the sigma vs. delta1, and the curve with circles on it means
sigma vs. delta2. I think I can use 'expression' to write delta1, delta2
and sigma in greek letters, but I am not sure how to denote the square and
cirle I graphed.

TO be specific, here is how I graphed

plot(sigma, delta1, ylim=range(-0.5, 2), xlab='sigma',
ylab='delta1--square delta2--circle', pch=22, type='o')
par(new=TRUE)
plot(sigma, delta2, ylim=range(-0.5, 2), xlab='sigma',
ylab='delta1--square delta2--circle', col='red', axes=FALSE, type='o')

Thanks a lot

How about

plot(sigma, delta1, ylim=range(-0.5, 2), xlab='sigma', ylab='delta',
pch=22, 
type='o')
points(sigma, delta2, col='red', axes=FALSE, type='o')
legend("topleft",c("Delta1","Delta2"),fill=TRUE,col=c("black","red"))

Send runnable example next time.

Thanks for your reply.  It is very helpful. I am sorry I didn't make  
my
queston clearer.
I have two concerns about this graph.
One thing is denote 'sigma' and 'delta' as greek letters, usually I  
use
'expression'. But I don't know how to use 'expression' in the 'legend'
The other thing is, the graph will also be print out with black and  
white. I
try to use circle and squre to seperate 'delta1's curve and  
'delta2's curve.
So even someone read the black and white handout, they can tell  
which graph
is which.  It will be nice if there is a notation on the graph, next  
to a
square symble, it says 'delta 1', next to a circle symble, it  
says'delta 2'.
I wrote it on the label with phrases, looks not professional.

Thank you for any suggestons.

my runable code is as follows:

sigma=c( 0.00625, 0.06250, 0.12500, 0.18750, 0.25000, 0.31250,  
0.37500,
0.43750, 0.50000,
0.56250)
delta1=c(0.90768, 0.90489, 0.901788,0.898681, 0.8955, 0.89557,
0.892474,0.88936, 0.886262, 0.179959)
delta2=c(0.90830, 0.9110998, 0.914203, 0.917308, 0.920412, 0.923517,
0.926623, 1.71524, 1.7153, 1.7154)

plot(sigma, delta1, ylim=range(-0.5, 2), xlab='sigma', ylab='delta1-- 
square
delta2--circle', pch=22, type='o')
par(new=TRUE)
plot(sigma, delta2, ylim=range(-0.5, 2), xlab='sigma', ylab='delta1-- 
square
delta2--circle', col='red', axes=FALSE, type='o')

Joh, thank you very much. sorry for confusing you. I didn't make my
question
clear.  I tried your code it looks much better than my original one. Just
I prefer I can write the greek letter delta1 and delta 2 instead of words
'delta1' and 'delta2'. Also, it will be nice if there is a square symbol
next to delta1 and a circle symbol next to delta 2, since sometimes I have
to print the graph in a white and black paper. Thanks for any suggestions.
Sorry for not asking question clearly.

Thank you again, Joh

Based on your code seems I solved the problem.
new code as follows:
cs<-expression(delta[1], delta[2])
plot(sigma, delta1, ylim=range(-0.5, 2), xlab='sigma', ylab='delta',  
pch=22,
type='o')
points(sigma, delta2, col='red', axes=FALSE, type='o')
legend("topleft", cs,    pch = c(21, 22), lty=1, col=2:1)

only concern is there is a waring message in R: Warning message:
In plot.xy(xy.coords(x, y), type = type, ...) :
 "axes" is not a graphical parameter

You should not be specifying axis types or flags to a function, [ 
points() in this case] that is not intended to do anything with the 
axes. To be Biblical: If thine warning offend thee, pluck it[the 
argument] out.

Dear All,

One more nlmeODE question:

I have a differential equation where one of the parameters depends on 
time. Values of this parameter at fixed time points are known but need 
to be interpolated between these known points. Can it be implemented in 
nlmeODE solver?

Thanks
Leonid
