Hi, I would like to use the segments command within a lattice graph. Is this allowed in R in the same way as in SPlus? If not, what is the alternative? For example, the following produces vertical line segments between points in SPlus but in R the line segments are not shown. (I want to replicate in R what I see in SPlus.) What is my mistake? library(lattice) set.seed(123) dat <-

I have some difficulties in reading big dataset; I have to import a dataset with 1'661'852 observations saved in a 51.4Mb - txt file. I was wandering if this is a memory size problem or if I realy can't import such big datasets. If the memory allocated to my R is not enough, I would like to know exactly which comands I should use in order to read and use my large dataset. I

Hi, How can I include accents and signs like '?' '?' in the plots generated by R? I try, but R automatically transforms the name ex: > countries <- c("M?xico", "Espa?a") > countries [1] "M\216?xico" "Espa\216?a" > I've seen in some Spanish texts about R how is it normal to include labels of the plots and other names with

Hi everybody, I have some troubles by using R with weighted data. It is very easy to obtain the mean of a weighted data set due to the function weighted.mean, but unfortunately, such a function is not available for any other estimators. Is there a comfortable way to consider the column with the weights which would not lead to an expansion of the sample (what would apply by using the rep()

hi, I want develop a cli cmd to create snapshot, but glusterd op sm & hook looks complex, Are there development guides or docs about cli & glusterd backend process? Thanks. --terrs

Dear R-"helpers"! May I kindly ask the pure statistics-experts to help me for a purpose which first part is not directly concerned with R. Consider two distribution functions, say f and g. For both, the median is smaller than a half. Now, the multiplicative or additive linkage of both distribution leads to a new distribution function, say h, whereas the median of h is greater than a

Hi, I have troubles when trying to login to my SAMBA Domain, joinung the workstations to the domain was no problem, browsing shares is no problem, but no damain login.

Hello all, Would somebody be kind enough to show me how to do a KS test in R for a lognormal distribution with ESTIMATED parameters. The R function ks.test()says "the parameters specified must be prespecified and not estimated from the data" Is there a way to correct this when one uses estimated data?

Thank you for your prompt answer. The breathing signal observations are the amplitude values as a function of time and phase. According to our model the hidden states are the different breathing types. Subjects, whose respiratiion process is regular, are likely to breathe, keeping the same cycle pattern/type, for many consecutive cycles. therefore dwelling in the same hidden state. The more

Hi All, I'm setting up a gluster cluster that will be accessed via smb. I was hoping that the quotas.

I've Looked over the list of Auth methods that dovecot can use But i didn't see a option for a custom auth option. Would it be possible to add in a way for dovecot to call a script to check a users login info. have it able to retun the the homedir,gid/uid, and weather or not the password matched. -- Chris L.

Dear all, I'm trying to make an R code for the drought severity index (DSI) developed by Philips and McGregor (1998). You can refer to the description of the algorithm on page 19 from http://dissertations.port.ac.uk/229/01/MaloneS.pdf The code is given in Excel as the following and can be found on page 60 from the same link. C7 = IF(C6<0,IF(@SUM(A6:A1)<0,C6+A6,"0"),

Dear Community, does anybody have an idea on how to estimate a system of three seemingly unrelated regressions, two of which being TOBIT and one OLS? Background: I am currently estimating a translog cost function and two corresponding cost share equations using systemfit and the seemingly unrelated regression ("SUR") specification. However, I consider it more appropriate to estimate

I need to split some information up between two servers, and wanted to use REST for it. I can write the REST server really easily...but I don''t know how I can actually use it. I downloaded Rails trunk to mess with ActiveResource, but it seems that it doesn''t have create functionality enabled yet. Is it possible to use AR fully? If not, what''s the best way to consume

Hi guys, I'm quite new to R but quite enthousiastic. I'm trying to rewrite a bit of code in order to make it faster, so instead of nesting for loops I'm trying some apply functions. Since it's a combination of lists of matrices and other matrices, I would like to use lapply() on the list and still be able to use the list index to index in the matrices. So, in "code
