Hi everyone, I currently do some statistics about my heart rate variability. I've a CSV file which looks like this: Date Time ts_mean_RR ts_sdnn_RR ts_mean_HR ts_sdnn_HR ts_rmssd 1 20110905 07:21:50.0 1139.8298 40.3053 52.7393 2.2824 45.7958 2 20110906 07:11:37.0 1182.7333 49.1861 50.8665 2.4983 60.2329 3 20110907 07:21:31.0 1136.6028 49.4682 52.9566

Thanks people! another question, is there something similar to sort for dates? sort(x, decreasing = FALSE, ...)

How do I sum 15 years to my dataset? original dataset dates val 1 2001-01-12 1.2 2 2001-02-12 1.2 3 2001-03-12 1.2 result dates val 1 2016-01-12 1.2 2 2016-02-12 1.2 3 2016-03-12 1.2

Hi, I wanted to learn how to solve a date and time manipulation where i can do the following two 1. difference of two dates eg (differnce between 5th jan 2013 and 1st jan 2013) 2.Suppose i have week number of the year, i want to know if i can find out the day it refers to eg( say week 2 of 2013 would be 6th jan 2013 and the day is sunday) i need my result to tell me that its

Hola a todos/as: Tengo una curiosidad: ¿existe una función en R que devuelva el nº de horas a partir del nº de años?. Se trataría de computar cada año con 6 horas extra sobre las 365, para así "prorratear" las 24 horas del año bisiesto. El cálculo es sencillo de hacer, lógicamente, pero me pregunto si hay algo hecho al respecto... Gracias. Eva [[alternative HTML version deleted]]

Hi all, hope someone can help me out with this. Background Introduction I have a data set consisting of data collected from a questionnaire that I wish to validate. I have chosen to use confirmatory factor analysis to analyse this data set. Instrument The instrument consists of 11 subscales. There is a total of 68 items in the 11 subscales. Each item is scored on an integer scale between 1 to 4.

Greetings, I am trying to model a time series using arima(). For getting the model order components(p, d, q and P,D,Q) I am using procedure discussed in [1] in section 3.2 . It is most likely hit and trial method based on lower AIC value. I want to know what is the correct way to find model order components or the method described in [1] is the appropriate one. thanks in advance. -- [1]Automatic

I'm searching for an r command that will notify me if I create a time that does not exist due to Daylight Savings Time. For example, if I run the following command on a windows machine > ISOdatetime(2010,03,14,2,10,0, tz = "") # My system time is set to the United States Central Time Zone [1] NA R returns NA, which is the behavior I want. However, if I run the same command on a

Hello, I want to start testing using the MNP probit function in stead of the lrm function in my current experiment. I have one dependant label and two independent varaibles. The lrm is simple model <- lrm(label ~ val1 + val2) I tried the same thing with the mnp function and got an error that I don't understand model <- mnp(label ~ val1 + val2) I get back an immediate error that

I use mnp to run a multinominal probit regression model, but the summary doesn't contain the model statistics, such as the log-likelihood and degree of freedom, for the assessment of the goodness-of-fit of the fitted model. Is there any way that I can generate these statistics for the fitted model in R? Many thanks in advance! SC

I am using AUTO ARIMA for forecasting. But it is not detecting 'seasonality term' of its own for any data. Is there any other method by which we can detect seasonality and its frequency for any data? Is there any method through which seasonality and its frequency can be automatically detected from ACF plot? -- Siddharth Arun, 4th Year Undergraduate student Industrial Engineering and

I'm trying to apply a function defined in the VW R docs, that attemps to convert a data.table object to Vowpal Wabbit format. In the process i'm getting the error in printf mentioned in the subject. The original function is here: https://github.com/JohnLangford/vowpal_wabbit/blob/master/R/dt2vw.R Below there is a small example that reproduces the error. The function works great with

Wouldn't it make sense to have this in the man page? The 8192-byte limitation for 'fmt' is mentioned but not this one. Thanks, H.

Hola, soy nuevo en R y en esta lista de distribución, pero a ver si alguien me puede echar una mano. Tengo una matriz de datos con 1539 filas, constituida por 171 eventos distintos medidos 9 veces cada uno. Lo que quiero es, para cada evento, hacer una regresión lineal entre la variable dependiente medida 9 veces en cada evento y el tiempo, y obtener el valor de 'r' para cada evento.

All- I am interested in estimating a parameter that is the starting value for an ODE model. That is, in the typical combined fitting procedure using nls and lsoda (alternatively rk4), I first defined the ODE model: minmod <- function(t, y, parms) { G <- y[1] X <- y[2] with(as.list(parms),{ I_t <- approx(time, I.input, t)$y dG <- -1*(p1 + X)*G +p1*G_b dX <-

Hello, I am trying to select the following headers from a data frame but when I try and run the command it executes halfway through and give me an error at V188 and V359.

Dear list members, I would like to ask two questions, although the second one must have been answered a thousand times. 1) is there a simple way to estimate the influence of individual variables in PCR and PLS models? What I have in mind is a way to rank the variables according to their influence, using some numerical value of a statistic. 2) what is the proper way to cite a CRAN package? How

I am updating my lab manual in Spanish. How should I cite your supplements to Venables and Ripley 1997 and the scripts. Thank you very much Peter B. -- Peter B.

Dear R users, I used the multivariate random numbers generation function in MASS for my study. I wonder what is an approriate way to cite the library and its authors in my publication to express my gratefulness? best regards, Yu-Kang
