Acumulate assign on lapply list
Hi R users:
f1<-function(l1,idx){
f2<-function(i,l1) l1[[i+1]]<<-c(l1[[i]],l1[[i+1]][-1])
lapply(idx,f2,l1)
return(l1)
}
l<-list(c(1,2,3),c(4,5),c(6,7,8))
l2<-f1(l,1:(length(l)-1))
l2
I got:
[[1]]
[1] 1 2 3
[[2]]
[1] 1 2 3 5
[[3]]
[1] 4 5 7 8
But what I want in the last position of l2 is the acummualte of the
assignations...
I would like to have:
[[1]]
[1] 1 2

Probabilities from survfit.coxph:
Hello:
In the example below (or for a censored data) using survfit.coxph, can
anyone point me to a link or a pdf as to how the probabilities appearing in
bold under "summary(pred$surv)" are calculated? Do these represent
acumulative probability distribution in time (not including censored time)?
Thanks very much,
parmee
*fit <- coxph(Surv(futime, fustat) ~ age, data = ovarian)*
*pred <- survfit(fit, newdata=data.frame(age=60))*
*summary(pred)*
time n.risk n.event survival std.err lower 95% CI upper 95% CI

help (Crear bucle para generar un dataframe a partir de datos .mdb)
Hola,
Tengo un conjunto de bases de datos de una encuesta industrial para
diferentes años (1995-2014). Las bases de datos están en formato .mdb. A su
vez, cada base de datos tiene 3 tablas con una variable "ID" común (la
"llave") para vincular las tablas.
Quiero realizar análisis estadísticos para analizar la evolución de ciertas
variables.
Quiero armar un dataframe que

for() to lapply()
...-----------------------------------------------------------
LIST: list of data frames.
m:point of start merging.
result<-merge(LIST[[m]],LIST[[m+1]],by="key",all.x=T)
for (i in (m+2):length(LIST))
{
result<-merge(result,LIST[[i]],by="key",all.x=T)
}
The problem is the acumulative: "result<-merge(result,...)"
I can think in a function like this:
mergeListelem<-function(i,LS,m)
{
merge(LS[[m]],LS[[i]],by="key",all.x=T)
}
ind<-m:length(LIST)
lapply(ind,mergeListelem,LIST,m)
But I just obtain a list of merged data.frames,
and I don伮伌t kno...

Cisco vs Asterisk
Hello all,
A client of us, is thinking to migrate their actual PBX to a Cisco
CallManager. We want to sell him an asterisk box to complement the
Cisco PBX.
I think to use asterisk as a Voicemail server (Replazing the Cisco Unity)
Has asterisk all the functionalities to replace a CIsco Unity server?
Which functionalities Cisco Unity has than asterisk could cover?
How could asterisk complement the
