boxplot help
Hi, im a newbie with very wobbly coding abilities.
Tearing my hair out over getting the boxplot i want...
I have a dataset called 'eagle' which consists of year (2011 or 2012), month
(jan - dec), roof (TT6, TT13 or BARE) and temp (the continuous variable that
i want to plot).
So i want boxplots of the three roof treatments in every month organised in
chronical order along x axis 2011 -

Mixed effect models
I am using two mixed effect models. Firstly, what I am trying to do is to
compare green roofs abundance with brownfield, green roof with green space
abundance, and finally green
space with brownfield abundance. I am unsure if I have done the
correct model. I have to use a mixed effect model because my data is
nested.
This is the code and output

ntp time server
Currently, my time server is a Sun v240 with a 32-pci gps card (with a
proprietary Solaris driver) attached to our gps receiver via an sma
cable up to the roof of my building. As I'm migrating almost all of
our Solaris servers and services over to CentOS, I'd like to know what
other people are using for time server hardware. Any suggestions?

Find reason for heavy load
My Centos 5 server has seen the average load jumped through the roof
recently despite having no major additional clients placed on it.
Previously, I was looking at an average of less than 0.6 load, I had a
monitoring script that sends an email warning me if the current load stayed
above 0.6 for more than 2 minutes. This script used to trigger perhaps once
an hour during peak periods. Even so, I

XP 2.2.8a issues
I have some 30 XP boxes in one offices joined to a w2k domain. The w2k
server has no problem mapping drives on the samba server, however, the
XP workstations refuse. Put in user name and password in the box after
mapping, and it just pops back up like you've entered a wrong pass/user
name. I have changed signorseal to 0 in registry to no avail. Of
course, when the server was NT4, I

Do I need a dedicated firewall?
Hi All,
So my electricity bill is through the roof and I need to pair down some
equipment.
I have a CentOS 6.5 Server (a few TB, 32gb RAM) running some simple web
stuff and Zimbra. I have 5 static IP's from Comcast. I am considering
giving this server a public IP and plugging it directly into my cable
modem. This box can handle everything with room for me to do more.
Doing this would allow

Contour lines in a persp plot
Hello folks,
i'm a R beginner and i want to put in a same plot both contour lines
and persp plot.
For example,
fn<-function(x,y){sin(x)+2*y} #this looks like a corrugated tin roof
x<-seq(from=1,to=100,by=1) #generates a list of x values to sample
y<-seq(from=1,to=100,by=1) #generates a list of y values to sample
z<-outer(x,y,FUN=fn) #applies the funct. across the combos of x

Load Testing
Guys.
How and which tools to use to load test an asterisk install? Say for
example, you need to see how many calls can be routed thru before losing
quality and making the cpu jump to the roof?

2 sample wilcox.test != kruskal.test
Hello,
I think I am right in saying that a 2 sample wilcox.test is equal to a 2
sample kruskal.test and
a 2 sample t.test is equal to a 2 sample anova. This is also stated in the
?kruskal.test man page:
The Wilcoxon rank sum test (wilcox.test) as the special case for two
samples; lm together with anova for performing one-way location analysis
under normality assumptions; with Student's t

creating a file of p.values
Hi all,
I am performing hundreds of kruskal wallis tests and trying to figure out
how to create a file of the p.values I obtain.
This is the code I use for the tests:

A3<-kruskal.test(X3~treatment)
A4<-kruskal.test(X4~treatment)
A5<-kruskal.test(X5~treatment)

DNS issues after FSMO seize
Aaaaaaand more problems... Welcome to the continuing saga of FILER.
It appears that neither SOA or NS records were updated during the process
of moving fsmo roles to CBADC01. SOA entries on all three active DCs point
to FILER. There aren't any NS records for any of the new DCs, only FILER.
In RSAT each DNS server's properties show filer.cb.cliffbells.com is the

Kruskal Walllis test
Hi all
My data table (g) contains a continues data column (plant.height) and other

each with number of levels of different factors. ANOVA test was done and
the p-values were extracted
as follos:
a <- function(x) anova(lm(plant.height ~ x))$"Pr(>F)"[1]
r<- apply(g[,8:57],2,a)

post-hoc test with kruskal.test()
Dear R users,
I would like to know if there is a way in R to execute a post-hoc test
(factor levels comparison, like Tukey for ANOVA) of a non-parametric
analysis of variance with kruskal.test() function. I am comparing three
different groups. The preliminary analysis using the kruskal-wallis-test
show significance, but I still don''t know the relationship and the
significance level

contour lines on persp plot
Hello folks,
I am a beginner R user. I have been able to make a 3D surface plot using
'persp'. The surface is made by a grid of lines emanating perpendicularly
from each of the x and y axes at regular intervals.
I can get rid of that grid by setting 'border=NA'.
Can anyone suggest some ways to replace the grid with contour lines, to
create a 3-dimensional contour map?
Thanks
