'sep' argument in reshape()
I wonder if the 'sep' argument in reshape() is being ignored
unintentionally:
## From example(reshape)
df <- data.frame(id=rep(1:4,rep(2,4)),
visit=I(rep(c("Before","After"),4)),
x=rnorm(4), y=runif(4))
reshape(df, timevar="visit", idvar="id", direction="wide", sep = "_")
id x.Before

ping latency using vhost_net, macvtap and virtio
Hi all,
I have been testing network throughput and latency and I was wondering
if my measurements are as expected.
For the test, I used Fedora 17 for both host and guest, using kernel
3.5.2-3.fc17.86_64.
Pinging an external server on the LAN from the host, using a gigabit
interface, the results are:
# ping -c 10 172.16.1.1

Hello,
could anyone explain what am I doing wrong. When I use colldiag function from package perturb I get different Variance Decomposition Proportions matrix in R than in SAS, although the eigenvalues and indexes are the same.
Thanks for your attention.

MCMCpack: Selecting a better model using BayesFactor
Dear R users,
Thanks in advance.
I am Deb, Statistician at NSW Department of Commerce, Sydney.
I am using R 2.9.1 on Windows XP.
This has reference to the package “MCMCpack”. My objective is to
select a better model using various alternatives. I have provided here
an example code from MCMCpack.pdf.
The matrix of Bayes Factors is:

write.table problem
Dear R helpers,
I have been using the loadings function from the multiv library and I

"Error in as.data.frame.default(x[[i]], optional = TRUE) : can't coerce
loadings into a data.frame" Any idea why write.table is doing that and

a +1 shift overlaying lines/points on a boxplot (PR#398)
Full_Name: Adrian Custer

When I create a boxplot, and then try to overlay a lowess fit or just the
points,
the points do not appear in the highest level and the lowess curve does not
reach
the highest level. However, if I add one to each of the models, the problem is
solved.

plot(survfit(fitCox)) graph shows one line - should show two
R 2.8.1
Windows XP
I am trying to plot the results of a coxph using plot(survfit()). The plot should, I believe, show two lines one for survival in each of two treatment (Drug) groups, however my plot shows only one line. What am I doing wrong?
My code is reproduced below, my figure is attached to this EMail message.

Diag "Hat" matrix
Hi R users:
What is the difference between in the computation of the diag of the
"hat" matrix in:
"lm.influence" and the matrix operations with "solve()" and "t()"?
I mean, this is my X matrix

newbie question on contrasts and aov
I try to move from SPSS to R/S and am trying to reproduce the results of SPSS
in R. I calculated a one-way anova with "spk" as experimental factor and erp

The result of the Anova are the same concearning the mean square, F and p
values. But I also wanted to caculate the contr.sdif(4) contrast on spk. The
results are completely different now. I hope anybody can

Systemfit
Sadly you failed to set your email program to send plain text and the data is corrupted at my end.
I also think you need to reduce the size of the data set... the intent here is to increase your understanding, not debug your particular analysis.
I will say that I am having a very challenging time understanding what you are trying to accomplish though. What are the equations that you think need
