Thank you very much. I will use 1.7.1 version. Have you had time to look at
the issue regarding a weird behaviour of multinomial glmnet when alpha=0? I
posted it to r-help more than two weeks ago and maybe you missed it. Damjan

Hi,
when I use the install.packages() function this make a download of

Dear R users,
I'd like to announce the PairedData package (version 0.5). This package
provides a set of graphical tools (based on ggplot2), statistics, effect sizes
and some classical and robust tests, confidence intervals and random simulation

Dear expeRts,
I would like to color a certain region in a levelplot. The region for z = 0.02
should have a dark gray color. Below is a minimal example. It almost does what
I want, but The region between z=0.02 and z=1 is also colored in dark gray
(instead of just the region for z = 0.02).

Colleagues,
I am working with a CSV file; for testing purposes, I created an XLS version of

Hi all,
Are there base functions that do the equivalent of this?
fliptb - function(x) x[nrow(x):1, ]
fliplr - function(x) x[, nrow(x):1]
Obviously not hard to implement (although it needs some more checks),
just wondering if it had already been implemented.

I have two large datasets (156K and 2.06M records). Each row has the
hour that an event happened, represented by an integer from 0 to 23.
R's histogram is combining some data.
Here's the command I ran to get the histogram:
histinfo - hist(crashes$hour, right=FALSE)
Here's histinfo:

Hi,
I think you're not understanding quite what's going on with hist. Reread the
help, and take a look at this small example. The solution I'd use is the last
item.

1 2 3 4 5 6 7 8 9 10

can you please tell me how to do it??? I know it is extremely

you can help
Hadley:
Dunno.
But if not, it seems to me that it should be added as an array method
to ?rev with an argument specifying which indices to rev() over.

Presumably for fliplr you meant ncol(x)
fliplr - function(x) x[, ncol(x):1]

Here is a test I ran and looks fine, but then I created the data, so
it might have something to do with your data:
x - sample(0:23, 10, TRUE)
a - hist(x, breaks = 24)
a[1:5]
$breaks
[1] 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23
$counts
[1] 8262 4114 4186
Fast fingers; notice that there is still a problem in the counts; I
was only looking at the last.

If you just want a plot of the frequencies at each hour why not just call
barplot on the output of table? Histograms create bins and count in those,
which doesn't sound like what you're after.
