For many entries, it would be faster, if you just allocate
the array that should be written, by just writing 0 into it,
or empty strings or something like this...
mydat[1:100] <- 0
Simpler is
mydat <- numeric(100)
> mydat
[1] 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
0 0 0 0 0 0
[38] 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
0 0 0 0 0 0
[75] 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
mydat <- 1
mydat[2] <- 33
mydat[3] <- -4
mydat
[1] 1 33 -4
instead of "mydat[1:100] <- 0"
use the length of the itemlist as second parameter.
Ciao,
Oliver
