Hello, I see that "mclust" is a pacakge that handles fitting mixtures of normals. Are there any other packages out that that can handle mixtures of gammas or other exponentials? Additionally, are there any packages out there that can fit bimodal distributions without mixtures? i.e., Cobb et al. 1983 using moment recursion relations? Thank you! mw Marion Wittmann, Ph.D.

Hi, I have a data matrix in which there are 1000 rows by 30 columns. The first column of each row is a numeric indicating the number of trips taken to a particular location with location attributes in the following column entries for that row. I want to repeat each row based on the number of trips taken (as indicated by the number in the first column)...i.e., if 1,1 indicates 4 trips, I want

Greetings, I am using the nlm function in a minimization exercise but have consistently received the code: "last global step failed to locate a point lower than 'estimate'...." So it seems that this function is only finding a local minimum, not necessarily a global minimum. Does anyone have a suggestion or recommendation for an alternative package or function within R

Hi, Marion, I believe the package FlexMix provides a more generalized version of finite mixture modeling than is found in mclust/mclust02.

Hello, I am using the package "flexmix", specifically the function "stepFlexmix" and was hoping for some assistance: Here is my input: fit <- stepFlexmix(trips~.,data=data.frame(traveldata),k=1:5,nrep=5,model=FLXMRglm( family="gaussian")) And I recieve the following error message: *Error in FLXfit(model = model, concomitant = concomitant, control =

Hello, I am using the bubble plot and have been able to overlay two different data sets on the same graphic successfully. I would like to do the following and cannot: 1) suppress the zero values such that there is no representation of them on my plot (i.e., the "zeroes" show up as the smallest dot size, and I can't change this) 2) Give values to y or x axes with values, and

hi, i hope i'm not reporting something well-known; i tried to understand the available bug tracking information. please excuse me if my problem report should not meet your standards, but i want to direct your attention to the following: http://koffein.org/av/rsync-bugreport/ problem report for rsync 2.6.9 on linux/IA32, 09 Dec 2006 Herwig Wittmann

Dear all, As I resume my dissertation work next month, I'd like to actually start an R package this time around. I haven't done so because I update my code very often (still in development phase), so running the skeleton function, running checks, building, and re-installing the package onto the system seemed like a long and tedious process. I would like to hear your experience on how

Dear list, I remember running into a thread on this topic in one of the R mailing lists before but I can't seem to find it now. Basically, I remember a discussion on how one can set up where R packages can be installed so that when we upgrade the R version on the machine, the packages are still accessible. One can back up this package location as well and bring it to a new computer. I

Dear R-users, i have a simple problem maybe, but i don't see the solution. i want to find the entry-wise closest element of an vector compared with another. ind1<-c(1,4,10) ind2<-c(3,5,11) for (i in length(ind2):1) { print(which.min(abs(ind1-ind2[i]))) } for ind2[3] it should be ind1[3] 10, for ind2[2] it should be ind1[2] 4 and for ind2[1] it should be ind1[1] 1. but with the

Dear R useRs, with the following piece of code i try to find the first value which can be calculated without warnings `test` <- function(a) { repeat { ## hide warnings suppressWarnings(log(a)) if (exists("last.warning", envir = .GlobalEnv)) { a <- a + 0.1 ## clear existing warnings rm("last.warning", envir = .GlobalEnv) }

I'm interested in feedback on my latest blog post, "Seamless web video within reach": http://ossguy.com/?p=424 It primarily describes how to get Theora working in Safari and Internet Explorer and how to bring it all together with tools like Mv_Embed. In addition, I'd like to find people that are interested in developing and testing the solutions I outlined (especially Mac and

Hi, R-users, data is a matrix like this AMR BS GE HR MO UK SP500 1974 -0.3505 -0.1154 -0.4246 -0.2107 -0.0758 0.2331 -0.2647 1975 0.7083 0.2472 0.3719 0.2227 0.0213 0.3569 0.3720 1976 0.7329 0.3665 0.2550 0.5815 0.1276 0.0781 0.2384 1977 -0.2034 -0.4271 -0.0490 -0.0938 0.0712 -0.2721 -0.0718 1978 0.1663 -0.0452 -0.0573 0.2751 0.1372 -0.1346

Assuming I have a Rails application running in the root folder of my domain. Now I want to put a clients'' app in a subfolder on that domain for review (or at least it *should* look like a subfolder). Can this be accomplished via .htaccess? It should not interfere with the Rails routing in the root folder. If .htaccess is the way, please help me out here, I suck at mod_rewrite... --

Dear R useRs, i wanted to ask if the folded normal destribution (Y = abs(X) with X normal distributed) with density and random number generator is implemented in R or in any R-related package so far? Maybe i can use the non-central chi-square distribution and rchisq(n, df=1, ncp>0) here? Thanks and best regards Andreas

I''d like to set up routes like /<section>/<article>. Using a route like map.connect '':section/:article'' works just fine, but I''ve also got an admin area that is accessed through the route ''admin''. Inside the admin area I''ve got subpages like admin/sections and admin/articles. This is conflicting with the other routes

I'm trying to find the total number of letters in a row of a data frame. Let's say I have the following data frame. f1 <- data.frame(keyword=c("I live in Denver", I live in Kansas City, MO", "Pizza is good")) The following function gives me the number of characters in each string. So for "I live in Denver", I get 1, 4, 2, and 6. However, I want to

Hi all, I dunno what I've done wrong, but since I upgraded my Samba 2.2.1a to 2.2.2 (Mandrake 8.0) I can see share called "nobody" in the list of shares on the server. Even I can't open it ( it asks for the password - I used guest, my login, root no success ) I can't seem to understand it. I have no share with this name in the smb.conf so I don't know what does it

Denver Gingerich has put together a quick frontend for ffmpeg2theora. It's written in Qt, so will run on OS X, Windows, and X11. You can find it here: http://github.com/ossguy/qtheorafrontend It doesn't do any sort of error checking right now, and currently assumes the video file is in the current directory and called "test.flv". It will convert the file, showing
