Dear all,
Possibly a rudimentary question, however any help is greatly appreciated. I
am sorting a large matrix into an array of dim(p(i),q,3). I put each entry
into a corresponding matrix (1 of the 3) based on some criteria. I figure
this will assist me in condensing code as I can loop through the 3rd
dimension of the array instead of generating 3 separate matrices and using
the same block of code 3 times. My question is how to get the colnames of
the 3 nested matrices in the array to match the colnames of the data
matrix. In other words...
DATA:
Exp region Qty Ct ...q
1 S CB 3.55 2.15 .
2 S TG 4.16 2.18 .
3 C OO 2.36 3.65 .
4 C . . .
. . . . .
. . . . .
. . . . .
p ...........................
ARRAY
1
[,1] [,2] [,3] [,4]...q
1 SOME DATA WILL FILL THIS .
2 . . . .
3 . . . .
4 . . . .
. . . . .
. . . . .
. . . . .
P(1) ...........................
2
[,1] [,2] [,3] [,4]...q
1 SOME DATA WILL FILL THIS .
2 . . . .
3 . . . .
4 . . . .
. . . . .
. . . . .
. . . . .
P(2) ...........................
3
[,1] [,2] [,3] [,4]...q
1 SOME DATA WILL FILL THIS .
2 . . . .
3 . . . .
4 . . . .
. . . . .
. . . . .
. . . . .
P(3) ...........................
Again, how to get those [,1], [,2]... to read (and operate) in the same
fashion as the column names in the data matrix? Also, am I interpreting the
dimensions of the array incorrectly? Please feel free to post any helpful
links on the subject, as I have found "dimnames" and "array" in the R-help
documentation unhelpful. Any help is greatly appreciated.
