Partitioning matrix
Let say, I have following matrix :
dat <- matrix(rnorm(40), 2, 20)
Now I want to partition this like this :
dat1 <- dat[1,]
dat2 <- dat[2,]
But point is that, dat1 and dat2 become vector object. How can I force them
to be matrix object with dimension (1x20) ?
Thanks,

plot error -- figure margins too large
...up IDs.
The set is similar to the following df.
df <- NULL
for ( i in 1:20)
{
tmp1 <- runif(1000,0,5)
tmp2 <- cbind(tmp1,i)
df <- rbind(df,tmp2)
}
Now I would like to plot the numeric column, stratified by the group IDs, in a single figure.
First, I partitioned the frame into a 1x20 array. Then I plot the numeric values of each group in a sub-plot.
Note that only should the left most y-axis be shown, and the x-axis is only the group numbers.
Also the margin between two sub-frame should be fairly small so it looks like only one figure, rather than 20 figures.
The following cod...

Stacking matrix columns
I wish to stack columns of a matrix into one column. The following
matrix command does it. Any other ways? Thanks.
