[R] paste dimnames problem

[Peter Wolf]

Try:
<<*>>=
n<-list(c("new","old","prg"),
        c("04h","24h", "48h"),
        c("000mM","010mM","025mM", "050mM", "100mM"))
unlist(lapply(1:3,function(x) paste(n[[1]][x],n[[2]][x],n[[3]][x],sep=".")))

@
output-start
Tue Apr 27 12:03:57 2004
[1] "new.04h.000mM" "old.24h.010mM" "prg.48h.025mM"
output-end

>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.
