R.010mM.04h.NEW.1 0.07 010mM 04h NEW

R.100mM.24h.OLD 0.40 100mM 24h OLD
I'd like to create a sub data frame containing all rows where Batch == "OLD"
and keeping the 4 colums. Assume that I don't know the order of the rows
(otherwise I could just do something like x[1:20,]).
I've tried x[x$Batch == 'OLD']...

paste dimnames problem
Hello,
I've the following list n:
> n
[[1]]
[1] "NEW" "OLD" "PRG"
[[2]]
[1] "04h" "24h"
[[3]]
[1] "000mM" "010mM" "025mM" "050mM" "100mM"
where
n <- dimnames(some.multidim.array)
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,...

This data frame is not the problem since, it gets generated on-the-fly per gene and is discarded afterwards (just that it takes some time to generate it).
Here comes the problematic routine:
