[R] paste dimnames problem

[Dimitris Rizopoulos]

Dear Arne,

you could use something like:

n <- list(c("NEW", "OLD", "PRG"), c("04h", "24h"), c("000mM", "010mM",
"025mM", "050mM", "100mM"))
dnames <- apply(expand.grid(n), 1, function(x) paste(x, collapse=""))
dnames

I hope this helps.

Best,
Dimitris

> I'm trying to define a generic function that generates meaningful
names from this list, e.g. NEW.04h.000mM would be the first name, then
NEW.04h.010mM, ... . Overall this would generate 30 names (3*2*5).
Here, this would be 3 cascaded loops, but the dimensions of the array
should be flexible.
