bootstrap vs. resampleing
Hi,
I understand bootstrap can be used to estimate 95%
confidence interval for some statistics, e.g.
variance, median, etc. I have someone suggesting that
by resampling certain proportion of the total samples
(e.g. 80%) without replacement, we can also get the
estimate of confidence intervals. Here we have an
example of 1000 obsevations, we would like to estimate
95% confidence intervals for odds

Converting to XTS loses data.frame structure
...bles:
However, converting to an XTS seems to break that.
Example:
=============================================
d <- (read.csv(file.path(dataDir,thisFile), as.is=T))
myXTS <- as.xts( d, order.by=as.POSIXct(strptime(paste(d$Date, d$Time), '%m/%d/%y %H:%M')))
head(d)
Date Obsever Val.1 Time
1 10/12/09 PL 15 12:44
2 10/12/09 PL 15 12:44
head(myXTS)
Date Obsever Val.1 Time

plot the number of replicates at the same point
Dear R-helper,
I want to plot the following-like data:
x y
1 1
1 1
1 2
1 3
1 3
1 4
......
In the plot that produced, I don't want to show the
usual circles or points. Instead, I want to show the
number of replicates at that point. e.g. at the
position of (1,1), there are 2 obsevations, so a
number '2' will be displayed in the plot.
Is my narrative clear? Is there a way to make the

Re: Biplot function of PCA
[was sent a wrong R-help address; manually resent by MM]
Hello
I'am using the 'biplot' and 'biplot.pincomp' functions of the 'mva'
package for my studies.
The biplot represents both the observations and the variables of a
matrix of multivariate data on the same plot.
The observations are represented by their numbers (the line of the data
matrix), but I would need to

help with interpreting what nnet() output gives:
Greetings list,
I am new to programming in R, and am using nnet() function for a project on
neural networking.
Firstly I wish to ask if there is any pdf explaining the algorithm nnet
uses, which could tell me what the objects of the nnet class, like 'conn',
'nconn, 'nsunits', n and 'nunits' mean, and how weights are calculated.
The package pdf has little or no

samba 3.0.0 Authentication with NTsp4
We have been running Samba 2.2.x for some time without problems.

On upgrading the Samba server to 3.0.0, (smb.conf file unchanged):
All WinNt clients fail to authenticare.
Win2k clients authenticate correctly.
On reverting back to Samba 2.2.x, all cleints
