R-help Digest, Vol 124, Issue 12
Folks, Sorry for butting in here. I ran the code from John Kane below and it worked fine. I did however get a deprecation message suggesting the use of ggpairs from the GGally package to make this chart. Unfortunately I haven't found the correct incantation to get the diagonal to display the density plots using the "diag" parameter. Any suggestions? Just trying to learn,

Creating yyyymm regexp strings on the fly for aggregation.
Folks, This question is somewhat related to a previous posting of mine. I just can't seem to create a generic solution. Here is a function that I found searching around the internet: splitIt <- function(x, n) {split(x, sort(rank(x) %% n))} I use it like so: > splitIt(1:12, 2) $`0` [1] 1 2 3 4 5 6 $`1` [1] 7 8 9 10 11 12 Or > splitIt(1:12, 4) $`0` [1] 1 2 3 $`1` [1] 4 5 6

The ZFS Read / Write roundabout
Hey all - Was playing a little with zfs today and noticed that when I was untarring a 2.5gb archive both from and onto the same spindle in my laptop, I noticed that the bytes red and written over time was seesawing between approximately 23MB/s and 0MB/s.
