I must have missed something simple, but still, i don't know what. I obtained my basic data as follows: x <- sprintf("SELECT m_id,sale_date,YEAR(sale_date) AS sale_year,WEEK(sale_date) AS sale_week,return_type,0.0001 + DATEDIFF(return_date,sale_date) AS elapsed_time FROM `merchants2`.`risk_input` WHERE DATEDIFF(return_date,sale_date) IS NOT NULL") moreinfo <- dbGetQuery(con,

I am feeling rather dumb right now. I created what I thought was a data.frame as follows: aaa <- lapply(split(moreinfo,list(moreinfo$m_id),drop = TRUE), fun_m_id) m_id_default_res <- do.call(rbind, aaa) print("==========================================") m_id_default_res print("==========================================") ndf <- m_id_default_res[, c('mid',

Dear maintainer, I used bioconductor package, pdInfoBuilder, to make a microarray platform annotation package. I named this package, pd.pdinfo.gpl11164.ndf.txt. This "self-made package" is to be used with oligo package. Prior to using oligo package, I need to install the annotation package, pd.pdinfo.gpl11164.ndf.txt, and cannot just copy it to the library tree. I tried using the

Hello, I am a new user of R and Linux (debian squeeze), and I am trying to install the ncdf library. First I don't know wich is the best to use (ncdf or ncdf4), But not matter the one I tried to install, it always failled. I try to find a solution to this common problem on the web, but I never find the good way to solve it. I hope you could help me I try many things during two days and now I

Hello! I have a function: zywnoscCalosc<- function( jedzenie, n1, n2, n3, n4, d1, d2, d3, d4 ) { ndf <- data.frame(nn1=n1,nn2=n2,nn3=n3,nn4=n4) ddf <- data.frame(dd1=d1,dd2=d2,dd3=d3,dd4=d4) for (i in 1:length(n1)){ wekt_n = ndf[i,] wekt_n_ok = wekt_n[!is.na(wekt_n)] dl_n = length(wekt_n_ok) wynik = (1*wekt_n_ok)/(1*dl_n) } } and I get an error like this: Error in 1 * wekt_n_ok :

There was a BioConductor thread today where the poster wanted to find pairwise difference between columns of a matrix. I suggested the slow solution below, hoping that someone might suggest a faster and/or more elegant solution, but no other response. I tried unsuccessfully with the apply() family. Searching the mailing list was not very fruitful either. The closest I got to was a cryptic chunk

Hello, I want to know what do you think about my function. I know that it isn't briliant :/ but what do you think? What I should do that my function will be better? (now is very slow and not ideal, sometimes I also get a mistake!) ########## My function ############################################# dzieci<-transform(dzieci, zywnosc=0) zywnoscCalosc<- function( jedzenie, sklep, n1, n2,

Hello, In the attached file training.csv (I apologize for the large file) I have 238 objects belonging to 13 classes, which are described by 183 properties. I would like to find a svm model for these objects. I tried the following R statements. library('e1071') datatraining <- read.csv("training.csv",head=TRUE) names<-names(datatraining) print("before

Hi, I have run into another problem using offsets, this time with the predict function, where there seems to be a contradiction again between the behavior and the help page. On the man page for predict.lm, it says Offsets specified by offset in the fit by lm will not be included in predictions, whereas those specified by an offset term in the formula will be. While it indicates nothings about

Hi, I am looking for a R package to draw 3d plot. But not in a static way like scatterplot3d or stuff like that. I would like to make rotate the plot, to zoom/unzoom etc..., actually to render the graph 'dynamic'... (for the biologist and bioinformatician, a R package which permitts to reproduce what pdb viewer does). Does a Way exist to do something like that in R ? Thanks,

Thanks a lot for help in advance. I am switching from matlab to R and I guess I need some time to get rolling.

Hi, I have a matrix of data values like the example bellow. I would like to extract a subset of the matrix for the values where the first column is negative. I am using the subset function. However, I am getting an error message that the conditional variable doe snot exist. For some reason, the subset operation only works if I transform the matrix to a data set using as.data.set().

Hello, we successfully migrated from a Samba 3.x NT Domain to a Samba AD Domain using Samba 4.7.x. However, there are still some issues and I hope for your help. The biggest problem so far follows: For historical reasons our Samba file servers carry a lot of aliases. Now that they have become AD Members I did set a lot of CNAMEs in the AD DNS (using the Windows DNS Tool). Most of the aliases

I'd say don't use simple dns aliases (cnames) in a DC, but use SPNs instead (see samba-tool spn). This will manage CNAMEs too, and also manages the KRB tickets and proper autentication of the server to the

Hi Everyone, I am currently reviewing the DNS records for the organization I work for and have one area I would like other peoples thoughts on. Would there ever be a situation where you need to have multiple A records pointing to the same IP Address? Currently we have a small number of cases where one IP Address has multiple A Records. This seems like a bad idea to me and I would replace
