This is a general question about Design of experiments. If i am not allowed to post general questions like this here please accept my apologies and ignore the question. I did a DOE with six factors in eight runs. I know i cannot check for interactions using this design, but i tried the interaction plot and it showed me many interactions. After this I foldover the design and ran the 8 runs to learn

Hello, I'm using ROCR to plot ROC Curves and I want to automate the saving of plots into PNG files using a custom function. My data frames are named like test1, test2, test3. Each data frame has three variables: method1, method2, goldstandard. Right now, for each plot I have to run: png('test1_method1.png') plot(performance(prediction(test1$method1, test1$goldstandard),

Let's say I have a data.frame like A B C TS other columns 1 1 1 12345 1 1 1 56789 1 2 1 23456 1 2 2 23457 2 4 7 23458 2 4 7 34567 2 4 7 45678 and I want the last row for each unique combination of A/B/C, where by "last" I mean greatest TS. A B C TS other columns 1 1 1 56789 1 2 1 23456 1 2 2 23457 2 4 7 45678 I did this simply in SAS: proc sort data=DF; by A B C descending TS

I have a set of time-series climate data with missing entries. I need to add rows for these missing entries to this data set. The only way I know to do this is unsing a foreloop, but this won't work on a list. I've tried to convert the list to a data frame, but that won't happen, either. I want to fill rows in this table: > newtest[10:15,] yrmos yearmo snow.sum snow.mean

Hi, I recently spent quite a bit of time trouble shooting a function that I had written only to discover that the problem I was having was with the comparison operator. I assumed that the following would return TRUE: > testMean <- 82.8 + 0.1 > testMean [1] 82.9 > testMean == 82.9 [1] FALSE Apparently this has to do with deciml places. Look: > newTest <- 82.0 > newTest [1]

Hi Accesses the $new method for a class defined in a package fails if the methods package is not loaded. I have created a test package with the following single code file: newTest <- function() { cl <- get("someClass") cl$new } someClass <- setRefClass("someClass") (This is similar to code actually used in the testthat package.) If methods is not loaded,

I have having problems trying to take a file recorded with Monitor and convert it to MP3. When I use 'play' to play the .wav file, it sounds fine. After bladenc'ing it, it plays at lightening speed, and the voices are all high pitch. I tried using sox to resample to 32000 before encoding, but that didnt work either. Do any of you convert your .wav files to mp3? Monitor call:

Hi, Is there anyone know if BUGS language allows the combination of variables as response such as Y[i] <- a*X1[i]+b*X2[i] Y[i] ~ dnorm(c,d) It seems doesn't work in my model. The problem is between two ######. The error message is > modelCheck("BayesBioMarker.BUGS") model is syntactically correct > modelData(paste("BUGS_data.txt",sep="")) data

Dear expRts, I just realized that the "..." argument in a function cannot be used without taking precautions sometimes. The following behaviour is what I stumbled upon: > myrepl <- function(length, fun, ...) { + replicate(length, fun(...))} > myrepl(20, sample, 1:5) [1] 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 > myotherrepl <- function(length, fun, ...) { + args <-

Dear R colleagues, as a result of my calculations regarding the inter-observer-variability in bronchoscopy, I get a confusion matrix like the following: 0 1 1001 1010 11 0 609 11 54 36 6 1 1 2 6 0 2 10 14 0 0 8 4 100 4 0 0 0 0 1000 23 7 12 10 5 1001 0 0 4 0 0 1010 4 0 0 3 0 1011 1 0 1 0 2 11

Dear R-colleagues, another question from a newbie: I am creating a lot of simple pivot-charts from my raw data using the reshape-package. In these charts we have medical doctors judging videos in the columns and the videos they judge in the rows. Simple example of chart/data.frame "input" with two categories 1/0: video 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 1 1 0 0

Hi all, First at all, excuse if this is not the right place for sending this email. I'm using ubuntu 14.04 server edition and i'm trying to deploy some virtual machines in a server in such a way that they are visible in the same network that the host machine. The tools I'm using are the uvtool package and libvirt. The error I'm getting is the following: "uvt-kvm: error:

Hi guys. Does anyone have problems with a similar configuration (mdbox)? Just tested with latest version (stage servers installation: dovecot 2.3.7), also affected. Not critical, but have complaints from users, 1-2 per month. 26.06.2019 12:05, Aleksandr ?????: > Copying or moving with email client: thunderbird, roundcube (webmail), mutt or any other email client via imap protocol. >
