Transparent Bands in R
Hello All,
My question is regarding the attached plot. I would like to have multiple
transparent green bands running the length (yaxis) of the plot the width of
which is determined by the green lines at y=0 in the plot. Can you suggest a
way to do it?
For those who can't or are unwilling to download the file the plot is at

Re-execute previous command
Hello All,
In bash, to re-execute a command, say, 'gnuplot plot.gnu', one can type
!gnu. Is there a similar feature in the R console? For example:
plot(g1$mean,g2$mean)
.
.
.
Lines, many lines of commands
->Here I want to repeat the previous plot command.
!plot and plot(+TAB) do not work.
This question was asked in this forum back in 2006 but the answer seems to
have been lost

Insert .eps files in to an R plot.
Hello Everybody,
I have an eps figure an awesome bacteria and a plot (generated using R) also
in eps format. Now it looks like there is space for only one figure and I
have to insert the picture of the bacteria into the plot. Is there a way to
insert figures (eps/png/jpg) in to plots (may be control over placement of
figures in the plot as well?) ? By plots I mean data represented using axes

Multiple figures margin problem
Hello All,
I am trying to make a figure with 3x2 plots in it. Let us name the plots as
such:
1 2
3 4
5 6
I begin my script with:
par(mfcol=c(3,2))
par(oma=c(0,0,0,0)) --> This is for a postscript figure so I really don't
need the outer margins.
d=5
par(mar=c(d,d,d,d)) --> This applies to all the 6 plots.
Now if d=0, plots 1-2,3-4 and 5-6 will have no gap between them and

Conditional read-in of data
Hello All,
I have a 40k rows long data set that is taking a lot of time to be read-in.
Is there a way to skip reading even/odd numbered rows or read-in only rows
that are multiples of, say, 10? This way I get the general trend of the data
w/o actually reading the entire thing. The option 'skip' in read.table
simply skips the first n rows and reads the rest. I do understand that once

Snom vs Polycom
Anyone got any subjective (!) views on the merits of these two ranges ,
using asterisk 1.4 ?
I need to supply approx 30 handsets to a new client, with the senior
managers (6) having some slightly more "managerial" phones than the base
phones which will be used for one line only.
TIA

Adjusted R-squared formula in lm()
What is the exact formula used in R lm() for the Adjusted R-squared? How can I interpret it?
There seem to exist several formula's to calculate Adjusted R-squared.
Wherry’s formula [1-(1-R2)·(n-1)/(n-v)]
McNemar’s formula [1-(1-R2)·(n-1)/(n-v-1)]
Lord’s formula [1-(1-R2)(n+v-1)/(n-v-1)]

entropy and conditional entropy for continous variables
Hi,
this is not a R question per se, but since I'm on the lookout for an R
solution I thought this was the best place:
I would like to calculate the entropy for a variable and the conditional
entropy between two variables, H(X|Y) for variables X & Y
I have coded the case for the categorical case but I'm having problems
understanding how to do it for the continous case.

function to compute entropy
Maybe its slightly off-topic, but can anybody
help with computing entropy on matrix of probabilities?
Guess we have a matrix of probabilites, A, 2x2, something
like this:
z
x 0 1 2 3 4
0 0.063 0.018 0.019 0.016 0.000
1 0.011 0.162 0.040 0.042 0.003
2 0.015 0.030 0.164 0.033 0.002

calculating joint entropy of many variables
Hello list.
I need help (e.g., a reference, code, package, etc.) in calculating the
joint entropy of many variables (some sure highly mutually-informative and
some not).
Is there anyone here who knows a computationally-efficient solution (such
as an R package)? I appreciate you help ...
Best, Reza

randomness entropy in DomU
Hello.
I was just digging around in the net and found the thread
http://lkml.org/lkml/2006/5/12/103
So my questions: Are there any (good) news concerning the implementation
of /dev/random in the kernel?
I just cat /proc/sys/kernel/random/entropy_avail
and saw I have about 250 in the DomU''s and 3500 on Dom0. I haven''t even
started to implement encryption for the different kind

Entropy based feature selection in R
I need to use entropy based feature selection to reduce term space while
doing text classification. Are there any R packages available that would
help me do this?
I can also make do with chi squared based algorithm, if there are packages
for that.
Thanks in advance.
