Hi, I have the following file, and I need to work out the linear regression for each sample. I tried the model(*) and receive the error message (**): > data=split(mydata,rep(1:(nrow(mydata)/6),each=6)) > arrang.linear=lapply(data,lm,formula=KA~PA) Erro em storage.mode(y) <- "double" : invalid to change the storage mode of a factor Al?m disso: Warning message: In

Please, I would like to know how to generate a truncated multivariate normal distribution k - dimensional, X ~ NT(mu, Sigma), where the elements of X to be non-negative (except the first), and the first dimension is strictly larger than zero. Example: X ~ NT_2(mu, Sigma), where mu=c(0.5, 0.5) and Sigma=c([120, 191], [191,154]), with X_1>0 and X_2>=0 Could anybody help

Hi. I'm trying to export a .wav file using the writeWave function from tuneR package in a different folder than the default getwd(). After reading through the manuals of some audio packages I couldn't figure it out. I'm picking one 3-hour .wav file and asking the function to take a sample of 1 minute (from minute 100 to minute 101 of the 3-hour file) and saving it in an object

1. Emma is performing an experiment that requires individual handling of some animals. The sizes of the animals are lognormally distributed: The natural logarithms of their sizes has a normal distribution with mean 3 and standard deviation 0.4. The time (in minutes) it takes to handle each animal is given by 10 + s · 1.5 + eε for animals with s ≤ 20 20 + s · 0.8 + eε for animals with s > 20

I was just wondering how (or indeed if) people use the %include directive in Kickstart configuration files when building systems via NFS. I've been trying to modularise our Kickstart files a little to make things more readable, having generic defaults and role specific stuff split out into separate configs. I've tried this configuration... [root at archive kickstart]# cat

Hi All, I have a very simple problem. I have several files in a same directory. I would like to send for an object only the files that finish in ".sens.". I execute the command below, files <- dir(pattern="*.sens") but it includes all of the files that have "sens", independent of they be in the end or in the middle of the name of the file. How could I solve

Hi, is it possible to use Asteriks for translating SIP to H323 and vice versa? I am looking to implement the following Setup SIP UAC <-> SIP-Server <-> SIP/H323 Proxy <-> H323 Server <-> H323 UAC Basicly i want SIP fones to talk to H323 fones and and SIP Fones to access PSTN Gateway(s) in a H323 network. Anyone got something similiar running? Any ideas? best regards,

I can call out fine etc. I did some network

Hi I would like to know how I can change the name of a model for each trainning cycle of a model. I work with the RSNNS package and to build a neural network, I used : for (i in 5:30) .... model_ANN <- mlp(X, Y, size=n,....) # where size is the number of neurons in the hidden layer but I need to save each time that the model that is build (the end of each cycle), e.g., when i = 5, I need to

Hola compañeros de la lista, qué tal. Los molesto con la siguiente duda: Tengo un experimento con dos factores A y B, cada uno de los cuales tiene los siguientes niveles (que son concentraciones de dos hormonas vegetales aplicadas a plantas): niveles del factor A: 0, 0.2, 0.5, 1 niveles del factor B: 0, 0.1, 0.2, 0.5, 1 y mi variable de respuesta es continua, todo dentro del set de datos

Dear All, I?m using lme to analyze a time series gene expression data. I don?t have all animals in all times, the number of animals in each time is different and I have lots of NA values. An example file can be downloaded at lbmp.fcav.unesp.br/leonardo and the code used is the following: teste<-read.table(file='example.csv',sep=',',header=T) B<-1366 library(nlme)

Hola a todos, Escribo para preguntarles sobre cómo programar algo, que estoy segura es algo bastante sencillo para muchos de Uds que tienen amplia experiencia programando. Lo describo a continuación. Tengo una base de datos (file = datos) de especies (de plantas) en donde cada fila es un individuo de una especie con ciertos atributos (alrededor de 1500 filas = individuos). Quería anexar en esta

Hi, I have a new (for me) situation. I have a function for one linear model: y = 9.7909-0.035*x I have the variance of system var = 13.01403 Is possible to create a random vector points of Y (simulating the real data) over this curve using the function and the variance? I need this to a discipline. I have this: | \ | \ -> y = 9.7909-0.035*x and var = 13.014 | \ | \ | \ | \
