...statistics to calculate for a large number of variables. I created a simple function to apply to variables. I would like the variable name to be placed automatically. I tried the following function but is not working. desc = function(x){ media = mean(x, na.rm=T) desvio = sd(x, na.rm=T) cv = desvio/media*100 saida = cbind(media, desvio, cv) colnames(saida) = c(NULL, 'M?dia', 'Desvio', 'CV') rownames(saida) = c(x) saida } desc(Idade) M?dia Desv...

...ear members, I am trying to use boot () to compute the distributions of a statistic of a data set. The statistic is defined in the following code: eds<-function(x) { r<-cor(x) paren<-1-abs(r)/2 denom<-sum(sum(paren)+0.5) desvio<-sd(x) media<-mean(x) a<-desvio/media nom<-sum(a*(sum(paren)+0.5)) eds_abs<-nom/denom print(eds_abs) } I need to calculate the nonparametric bootstrap confidence intervals for "eds_abs", but I...

...r *a las 3 variables númericas. Para la variable Aporte por ejemplo: descrip<-function(data) { grupos <- group_by(data, distrito) result <- summarise(grupos, media = mean(Aporte), maximo = max(Aporte), minimo = min(Aporte), desvio= sd(Aporte) ) return(result) } Pero me gustaría automatizarla para que corra para todas las variables del dataframe (3 en este caso pero van a ser mas de 23). Sugerencias??? Muchas gracias -- [[alternative HTML version deleted]]

Estimados todos: Me es grato escribir a esta lista de ayuda para R, ya que comparto 100% la filosofía de Software libre en especial software en Estadística ya que es la carrera que estoy siguiendo. El motivo de este mensaje es por un par de dudas que no pude resolver: 1. He utilizado las funciones para realizar pruebas de normalidad (kolmogorov-smirnov, cuando n>50) y (Shapiro, cuando

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I am trying to set the CDR(userfield) to a certain vaule using the application map of features.conf but I am not able to do it. When I receive a call I would like to tag it with a client code (3 digit numeric) so I can referenci it later from the CDR. I have edited features.conf with something like: code => #111,self,SET(CDR(userfield(111)) or

Yo, Inspired by the example in the tips & tricks-section of "http://www.junghanns.net/asterisk/", I built a more elaborate call divert-feature. This one validates if the extension a call-forward is to be set to is actually valid for the current context and additionally saves this context into the DB and always uses it to originate the divert from, as you can't expect the
