Hi,
Here are a few ways:
rep( list( new("track") ), 5 )
lapply( 1:5, function(x) new("track") )
list( new("track") ) [ rep(1, 5 ) ]

Hi
I am doing an simulation, and I a large proportion of the simulation
time is taken up by memory allocations.
I am creating an object, and storing it in a list of those objects.
essentially:
x <- list()
for (t in 1:500) {
x[1] <- new("track")
}
I would like to initialize in one go, to avoid the continuous
reallocation of memory when a new "track" is added, and fill it wit
the object created by new("track").
How can I do this?
thanks
Rainer
