More difficulties in getting data into R
In order to get around the problems of my posting a few minutes ago, I
thought:
$ awk -F\| '(NR > 2) {print $2}' cmie_firm_data.text > col2
$ awk -F\| '(NR > 2) {print $4}' cmie_firm_data.text > col4
$ paste col2 col4 | head -2
-510.45 -510.27

$ paste col2 col4 | tail -2

Drawing ticks in the 3rd and 4th row of a lattice
Dear all,
I want to draw ticks on the 3rd and 4th row of a lattice. How do I do this
? In my search of the help, I discovered a parameter alternating,which kind
of says where the ticks will be but does not suffice for me.
I am running this command : -
barchart(X03/1000~time|Company,
data=df1[which(df1$time!=1),],

I'm getting an error message (Error in round) when summarising a glm.nb

[RFC PATCH v6 00/92] VM introspection
The KVM introspection subsystem provides a facility for applications running
on the host or in a separate VM, to control the execution of other VM-s
(pause, resume, shutdown), query the state of the vCPUs (GPRs, MSRs etc.),
alter the page access bits in the shadow page tables (only for the hardware
backed ones, eg. Intel's EPT) and receive notifications when events of
interest have taken place

Help with saptial analysis (cluster)
Hi R-users
I'm a beginner with R and statistics, so I need some help to start my data
analysis. I've been reading some docs and tutorials on R and cluster analysis.
I've got a large dataset (102000 points) with values of longitude, latitude and
temperature and want to see if I can find groups (clusters).
Following some tutorials I can look for principal components but get an error

RODBC sqlFetch
Hi,
Thanks for showing me how to use RODBC and odbcConnect.
Now works nicely. The question I've got now is:
noms <- list.files(pattern=".DBF")
# removing extension names:
noms <- sapply(noms, function(x) as.character(strsplit(x,".DBF")) ,
USE.NAMES=F)
for (i in 1:length(noms)) {
s <- sqlFetch(bdades, noms[i])
# etc.
}
But it seems that sqlFetch()

chi-squared test
I don't quite understand the difference between the two methods for
performing a chi-squared test on contingency tables: summary(table())
and chisq.test()
They may different results. E.g.:
aa <- gl(2, 10)
bb <- as.factor(c(1,2,2,2,1,2,1,2,2,2,1,2,2,2,1,1,1,2,1,1))
aa <- c(aa, aa)
bb <- c(bb, bb)
table(aa, bb)
summary(table(aa, bb))
chisq.test(aa, bb)
Could somebody give me

Instalar paquetes antiguos en Windows 10

Estoy intentando instalar algunos paquetes antiguos en R (3.3.0), como ?devtools? en su penúltima versión, y me está resultando imposible. Instalé Rtools y R me dice que funciona, pero no consigo hacer que se instale el paquete. He probado bajando el paquete en formato .tar.gz y luego con las instrucciones:

Memory Read Only Enforcement: VMM assisted kernel rootkit mitigation for KVM
Hi,
This is my first set of patches that works as I would expect, and the
third revision I sent to mailing lists.
Following up with my previous discussions about kernel rootkit mitigation
via placing R/O protection on critical data structure, static data,
privileged registers with static content. These patches present the
first part where it is only possible to place these protections on
memory

matrix to coordinates
Dear R-users,
I'm sure it must be a specific function or a better way to convert
matrix to x,y,z coordinates (and viceversa), than my function below (it
works). Any help?
m2coord <- function(m)
{
k <- nrow(m)*ncol(m)
aa <- data.frame(r=1:k, c=1:k, v=1:k)
k <- 0
for (i in 1:nrow(m))
for (j in 1:ncol(m))
{
k <- k+1
aa$f[k]=i; aa$c[k]=j; aa$v[k]=m[i,j]
}
aa
}
