Thanks for looking at this.

The actual code looks something like this:

peaklabelNames <- c()
for(i in sequence(10)){
peaklabelNames <- append(
peaklabelNames,
substitute(i^{z+phantom()}*" ("*a*"AMU)",list(i="y2",z=2,a=0))
)
}

and is than used after 'plot' as

text(somex,somey,labels=peaklabelNames)

That doesn't work as described above.

Thanks for your time, Joh

I do not know what you mean by vectorized form. Can you give an example 
what you want to achieve and what you tried to do so?

[R] plot labeling and expressions

2008-01-15 Thread Johannes Graumann 
Hi all,

I'm trying to use an iteration that appends something to vector 'peaklabels'
like so:
peaklabelNames <- append(
peaklabelNames,
substitute(i^{z+phantom()}*" ("*a*"AMU)",list(i="y2",z=2,a=0))
)
The vector is supposed to be used with 'text' to put labels on signals in an
impulse plot.

While not vectorized
substitute(i^{z+phantom()}*" ("*a*"AMU)",list(i="y2",z=2,a=0))
works for me, the vectorized form doesn't. The labels are represented as 
"y2"^2 (AMU)
(note the '"' in the printed string). Can anyone please give me a hint on
how to resolve this?

Thanks, Joh
