Hi all, Is there a better to way to subset the ROWs (in the sense of NROW) of an vector, matrix, data frame or array than this? subset_ROW <- function(x, i) { nd <- length(dim(x)) if (nd <= 1L) { x[i] } else { dims <- rep(list(quote(expr = )), nd - 1L) do.call(`[`, c(list(quote(x), quote(i)), dims, list(drop = FALSE))) } } subset_ROW(1:10, 4:6) #> [1] 4 5 6 str(subset_ROW(array(1:10, c(10)), 2:4)) #> int [1:3(1d)] 2 3 4 s...

Another nicety may be handling network drives. I''ve been using a ruby script which manipulate using the "net use" command to map network drives, disconnect network drives, query to see what drives are connected, etc..., but it''d be sweet if this type of functionality was included in win32 pack...

Dear List, I am trying to solve a problem: I have approximately 100 Excel spreadsheets each with approximately 4 sheet each that I would like to download and import in R for analysis. Unfortunately i realized (i also sent an email to the author or xlsReadWrite() ) that the read.xls() doesn't allow to import the file in R from internet. Here it is the the code: ciao<-read.xls("http://www.giustizia.it/statistiche/statistiche_dap/det/seriest...

I''m attempting to run Puppet 3.2.3 on RHEL6 and am running into key problems.

I'm trying to fit a naive Bayes model and predict on a new data set using the functions naivebayes and predict (package = e1071). R version 2.5.1 on a Linux machine My data set looks like this. "class" is the response and k1 - k3 are the independent variables. All of them are factors. The response has 52 levels and k1 - k3 have...

Hi, I'm trying to convert my LDAP server into a LDAPS server to secure the users logins, but I don't know what's the procedure to do it. Someone knows any guide to do it? For now: - I've created a CA cert on the server - I've created the cert and key for the domain pdc - I've signed that cert with CA cert. - I've followed the post in samba wiki about LDAPS ( https://wiki.samba.org/index.php/Setup_LDAPS_on_a_DC). Now my quesiton is if i've to do anyting on Windows Machines to enable the LDAPS, because after enable the c...

Hello All, Recently I added some Nokia N95 customers and it worked pretty good. Now the customers are complaining about the dialing rules... They are used to dialing +12486543210 and +4479XXXXXX for long distance calls. Is there anyway to create a "+" sign dial plan which will allow them to dial a number with "+" sign. Cheers, Nit...

Dear friends. Please see the program below and answer if it does simulate a population of 1.000.000 families, each with at max 20000 children (typical in Denmark, you know), constructed such that each family stops having children when more boys than girls are present ? Equal numbers of boys and girls are g...

Perdón por anticipado ante una pregunta sólo achacable a mi ignorancia en programación. Estoy creando un nuevo paquete con una estructura "decente", en vez de las chapuzas que hacía hasta ahora. Defino una función que ajusta unos datos a una distribución que podemos llamar ND. La sintaxis de esta función sería, de forma resumida: ND.fit<-function(x, start, ...){ ... structure(li...

...d guess that -P imlplies -p, but that's an issue for your ssh maintainer. Also: you don't ordinarily distribute the private key. You need the PUBLIC key in $HOME/.ssh/authorized_keys on any system you want to access with the private key. Maybe i'm seing your application backward, and you are creating the key on the system being accessed, and putting the private key on all the systems accessing it. Anyway, the ssh-keygen -p changes only the private key. You could actually generate a key pair, put the public key on the system you want to access, put the private key on all...

Hello, I'm using pscl to run a hurdle model. Everything works great until I get to the point of making predictions. All of my "count" predictions are lower than my actual data, and lower than the "response" predictions, similar to the issue described here ( https://stat.ethz.ch/pipermail/r-help/2012-August/320426.html) and here ( https://stackoverflow.com/questions/48794622/hurdle-model-prediction-count-vs-response ).

But now i like to aggrigate the data by time. I tried to use time and frequency to make plots about values and time (e. g. plot the date over one day). Here a example of my...
