optimize simultaneously two binomials inequalities using nlm( ) or optim( )
Dear R users,
I?m trying to optimize simultaneously two binomials inequalities (used in
acceptance sampling) which are nonlinear solution, so there is no simple
direct solution. Please, let me explain shortly the the problem and the
question as following.
The objective is to obtain the smallest value of 'n' (sample size)
satisfying both inequalities:
(1-alpha) <= pbinom(c, n, p1)

optimize function help!!
Dear R users,
I?m trying to optimize simultaneously two binomials inequalities used to
acceptance sampling, which are nonlinear solution, so there is no simple
direct solution.
The 'n' represents the sample size and the 'c' an acceptance number or
maximum number of defects (nonconforming) in sample size.
The objective is to obtain the smallest value of 'n' (sample size)

multiword synoyms
I am using synoyms and cannot determine how to use them in following
example:
$db->add_synonym('Zfoobar','Zfoo Zbar')
or
$db->add_synonym('Zfoobar','Zfoo AND Zbar')
Or is this general not possible?

Unexpected result with lag() et diff() in plm package.
I have an unexpected result with the functions lag() and diff() in the plm
(panel data) package when used with transform(). These plm-specific
functions are supposed to generate lags and first differences within each
panel.
lag() does not work properly the first time (it reproduces the same
series--this is a common time series pitfall), BUT then it does work
properly when it is run a second

draw stripes in a circle in R
dear R users,
I would like to fill a circle with yellow stripes instead of a uniform
yellow color. To draw the circle I used the following command after
having loaded the (very nice !) plotrix library :

draw stripes in a circle in R
I don't see a question. If your question is whether R supports pattern fills, AFAIK it does not. If that is not your question, ask one.

problem with the behaviour of dashed lines in R plots
dear R users,
I am performing a linear regression with lm, and I would like to plot
the regressor in dashed lines. I know that the lty=2 option is the way
out, but it has a very strange behaviour: the line starts dashed but
then the spaces between each dash becomes very tiny and so the line
become somehow continuous for the human eye. Do you know how to fix that
problem, in order to have a

draw stripes in a circle in R
Sorry for that. Yes my question was whether or not and how is it possible to fill a circle of yellow stripes in R? Is it something that I have to precise in the color argument?
Thanks, best

problem with the behaviour of dashed lines in R plots
Hi,
It's because you are plotting a line between each of the points in
your data frame, and they are very close together:

1.8.1 Make problem on SunOS
I am trying to make R-1.8.1 on (SunOS shell1 5.8 Generic_108528-15 sun4u sparc SUNW,UltraAX-i2). I did
./configure

Configure output seems ok. The make proceeds until the following line appears, repeated indefinitely (until I break):

I suspect that this may involve write permissions (and maybe

abline is not plotting
Hello there,
I have some data I want to plot together with a best-fit line. (see MWE
below)
The points from the first plot does appear as expected, but the abline does
not appear, no matter what I change. I removed the log parameter before, but
the abline is a very steep line around the origin. I really want to keep the
logarithmic scale, plus a working abline.
Can someone help me with that?

draw stripes in a circle in R
hi david
Thank you very much for the hack of draw.circle that you proposed me.
I don't understand some part of the code, why do you pass radius as a
vector in the function (if I understand well the purpose of the for
loop) ? Also what is ymult?
If I set the radius to the value 0.85 as I wanted (so as a scalar), I
don't see any difference in the result when I call this function

Default value of the option initial in the ses function in the forecast package.
Dear All,
I am trying to use the function ses from the forecast package.

Usage:
ses(y, h = 10, level = c(80, 95), fan = FALSE, initial = c("optimal",

My query is that if I do not mention the initial value will its default
value be "optimal".

pictex
The example at ?pictex does not work (the driver apparently uses
'rotatebox') for me as stated. It did compile after including the
graphicsx package. A MWE is at the help page for pictex. I tried to
get in touch with Valerio but his email bounced. Probably we want to
add a \usepackage{graphicsx} to the help page and try to track down
Valerio.

legend: interplay between title and y.intersp
Hi,
my MWE is not working as expected:
plot(c(0,1), c(0,1), type="n")
legend("top", legend=c("", "", "a"), col=c("blue", "red", "green"),
title="test", y.intersp=0.2, lwd=1)
The lines are not below the title. I want (nearby) lines as in the plot,
but below the title. Is there a way to achieve this?

Some matrix and sandwich questions
Dear R-help,
I have a four-part question about regression, matrices, and sandwich package.
1) In the sandwich package, I would like to better understand the
meat() function.

(1/n * X'X)^(-1)
That is, for a simple regression (per the documentation on bread()):

Question: llvm-link type merge behaviour of c++ classes
Hi LLVM community,
I'd like to ask a question regarding the behavior of llvm-link:
My code contains Classes which are structurally equivalent but they are totally unrelated and distinct on a c++ point of view.
However, if the compiled IR gets processed by llvm-link, these types are merged together.
My question is: Is this expected behavior or a bug?
To explain it more in detail, a reduced
