BUG: Standard Time v. DST calculated wrong by Samba Server
FYI, the same bug apears if one mounts the file system
using "cifs":

More flexible aggregate / eval
Dear list,
I would like to do some calculation using different grouping variables.
My 'df' looks like this:
# Some data
set.seed(345)
id <- seq(200,400, by=10)
ids <- sample(substr(id,1,1))
group1 <- rep(1:3, each=7)
group2 <- rep(1:2, c(10,11))
group3 <- rep(1:4, c(5,5,5,6))
df <- data.frame(id, ids, group1, group2, group3)
df <- rbind(df, df, df)
df$time <-

Samba bug: 1 out of 387 files off by 1 hour (DST/ST bug)
Summary:
There appears to be a bug in the "time range" Samba is using on
dates where time is scheduled to "Spring Forward" from Standard
to Daylight Savings time. Might want to review the code for
"Falling back", as well...
Details:
This started out with my thinking it was an rsync problem, but
it appears to be something to do with how samba is exporting the
file

Substituting inside expression
I am having following problem:
I?m constructing model for calculation of area of triangle.
I know sides a, b, and gamma angle.
I wish to calculate the area using heron?s formula:
S <- sqrt(s*(s-a)*(s-b)*(s-c))
where
s <- (a+b+c)/2
and c is calculated using law of cosines:
c <- sqrt(a^2 + b^2 -2*a*b*cos(gamma))
since i am calculating a regression model, i need derivation of this

Incorrectness of mean()
I have found following problem:
I have a vector:
> a <- c(1.04,1.04,1.05,1.04,1.04)
I want a mean of this vector:
> mean(a)
[1] 1.042
which is correct, but:
> mean(1.04,1.04,1.05,1.04,1.04)
[1] 1.04
gives an incorrect value.
how is this possible?
thanks,
zbynek

How can I draw a line in empirical distribution function?
I've got the graphic with this:
a=c(120,40,75,85,55,75,55,90,90,55,155)
plot(ecdf(a))
How can I draw lines to show the lower quatile and upper quartil?
I only know there is the argument lines(),
but I don't know how to use it

How do I output all the R-squares of an SUR? summary(fitSUR$eq[[1:4]])$r.squared does not work
Greetings R Users,
I have a system of equations for which I would like to output all the
R-squares. Assume there are four equations in my system, the only way I
found to output all the R-squares is by calling them out one by one as this:
summary(fitSUR$eq[[1]])$r.squared
summary(fitSUR$eq[[2]])$r.squared
summary(fitSUR$eq[[3]])$r.squared

How to optimize function parameters?
Hi,
I have a dataset and I want to fit a function to it.
The function is variogram model (http://en.wikipedia.org/wiki/Variogram)
The variogram model is defined by three parameters and I want them to be
automatically optimized for real time data.
I tried to use gafit {gafit} for this, but there are some data
configuration, where optimal results given by gafit() are negative, which is
not correct

systemfit - SUR
Hello to everyone,
I have 2 problems and would be very pleased if anyone can help me:
1) When I use the package "systemfit" for SUR regressions, I get two
different variance-covariance matrices when I firstly do the SUR
regression ("The covariance matrix of the residuals used for
estimation") and secondly do the OLS regressions. In the manual for

Extreme AIC in glm(), perfect separation, svm() tuning
Dear List,
With regard to the question I previously raised, here is the result I
obtained right now, brglm() does help, but there are two situations:
1) Classifiers with extremely high AIC (over 200), no perfect separation,
coefficients converge. in this case, using brglm() does help! It stabilize
the AIC, and the classification power is better.

function to create multiple matrices
Hi All,
If given a dataframe (long form) with Year, Species, and Location,
How would I write a function that would create a unique matrix of Species &
Location for each Year?
What I've tried doing is the following:
data #dataframe
dataT<-table(data$Species,data$Location,data$Year) #creates tables of
Species vs Location for each Year
But I'm encountering issues individually

Stepwise logistic discrimination - II
I apologise for writing again about the problem with using stepAIC +
multinom, but I think the reason why I had it in the first place is
perhaps there may be a bug in either stepAIC or multinom.
Just to repeat the problem, I have 126 variables and 99 cases. I don't
know if the large number of variables could be the problem. Of couse the
reason for doing a stepwise method is to reduce this

R-alpha: is.vector(.., mode=..) bug (old)
It is clear, I think, that
is.vector(o, mode = "any")
should be TRUE whenever any of
is.vector(o, mode = "<something>")
is TRUE.
This is not yet the case, however, see below.
Consider the following examples which should be self-explaining.
Besides the above bug, they also show you that -- for S compatibility --
the mode argument should really use strings as
