Dear all, I have been trying to fit my data (only right censored) with gumbel distribution using fitdistrplus. I am getting very high standard error. I have been wondering why. The followings are the outputs: fit1=fitdistcens(dr0, "gumbel", start=list(a=99, b=0.6), optim.method= "L-BFGS-B", lower = 0.0, upper = Inf) > summary(fit1) FITTING OF THE DISTRIBUTION ' gumbel

Hi Jean, This is my last attempt at trying to use speex for a project we are working on. I have contacted you before, but i have had no joy what so ever trying to find a working example in c++ that shows how to add a header to a raw speex file, so that it an be played using windows. If you do know of a working example can you please supply a link. As this is a commercial project maybe you could

Sorry, that name is a misnomer.

Hello all, I've been working with R & Fridolin Wild's lsa package a bit over the past few months, but I'm still pretty much a novice. I have a lot of files that I want to use to create a semantic space. When I begin to run the initial textmatrix( ), it runs for about 3-4 hours and eventually gives me an error. It's always "ERROR: cannot allocate vector size of xxx

Hello, I am trying to calculate a 31 day running mean in some temperature data along ROWS. Rollmean() works great along columns, but how do I perform this same action on my rows? The data is a matrix of 365 columns (days of the year) by 5,000 rows (lat/long coordinates). I would like to perform a 31 day running mean along the 365 days. I am new to R so any help would be greatly appreciated!

Hello, I am developing an application using Qt framework and C++. I want to use R as statistics engine of my application. After doing some search on internet; I came to the conclusion that RCPP, MPI with RInside is what I need. The next logical task was to quickly tryout "qtdensity" project of RInside, for understanding the build and other settings. I hit some roadblock here and got

Hello, I'm new to R and would like to know how to create a vector of "rolling sums". (I have seen the Rmetrics package and the rollMean function and I would like to do the same thing except Sum instead of Mean.) I imagine someone has done this, I just can't find it anywhere. Example: x <- somevector #where x is 'n' entries long #what I would like to do is: x1

Hello useRs, I'd like to perform a moving average on the dataset, xx. I've tried combining the functions Reduce and rollmean but it didn't work. > r <- function(n) rollmean(n, 2) # where 2 = averaging interval > output < - Reduce("r", x) Error in f(init, x[[i]]) : unused argument(s) (x[[i]]) Is there anything wrong with the code in the first place? where

Hi, I used RODBC to import data from an Excel spreadsheet "*.xls", but some columns were returned as zeros. When I looked at these columns in Excel, I found that thery are results of formula calculations and not entry. My question is: Is there any parameter or command I need to use in order to overcome this problem? Thank you Ahmad Abu Hammour

Dear all, I am having a vector of around 300.000 elements and I Want to slide fast a window from the first element until the last-Windowsize what I have so far is the following for statement:  for (i in 1:(length(data[,1]) - windowSize)) {         out[i] <- mean(data[i:(i + windowSize - 1), ])         elements[i]<-length(i:(i + windowSize - 1))       } but this of course takes ages to

Hi, P-values in Durbin-Watson test obtained through the use of functions available in packages "lmtest" and "car" are different. The difference is quite significant. function "dwtest" in "lmtest" is much faster than "burbinwatson" in "car". Actually, you can take a nap while the latter trying to calculated Durbin-Watson test.

Hello all, Have some time series data stored in a data.frame, and am plotting it with ggplot2 (which is totally awesome). I have explored the documentation and mailing list archives, and I can't see any way to plot a 'smoother' that is just the K-step moving average. For example, imagine I had a data.frame called 'sleep' with 'date' as the date (from as.Date()) and

Hello R users, I am a researcher at the University of Michigan looking for a solution to an R problem.

Could anyone tell me a better way to achieve the output of this for loop? It seems to run quite slow. I'm sure there must be a more consise way to sum from FN to LN, excluding positive values, for each row. #sum between FN and LN, excluding positive values for(i in 1:R){ for(j in FN[i]:LN[i]){ if(Temp[i,j]<0) sum[i] <- sum[i] + sum(Temp[i,j])}} Cheers, R -- View this message in
