Dear R users I have a really simple question (hoping for a really simple answer :-): Having estimated the spectral density of a time series "x" (heart rate data) with: x.pgram <- spectrum(x,method="pgram") I would like to compute the power in a specific energy band. Assuming that frequency(x)=4 (Hz), and that I am interested in the band between f1 and f2, is the

Hi all I am running a 2-way repeated measure anova with 1 between-subjects factor (Group=treatment, control), and 1 within-subject factor (Time of measurement: time1, time2). I extract the results of the anova with: summary(aov(effect ~ Group*Time + Error=Subj/Time, data=mydata)) Now, this must be clearly a dumb question, but how can I quickly extract in R all the post-hoc t-tests for the

Dear all, I am unsure about how to specify a model in R and I thought of asking some advice to the list. I have two groups ("Group"= A, B) of subjects, with each subject undertaking a test before and after a certain treatment ("Time"= pre, post). Additionally, I want to enter the age of the subject as a covariate (the performance on the test is affected by age),

Dear R list I am looking for a function in R that computes the integration of a discrete curve, such as a power spectrum, in a specified interval (in my case, that would be 'power in a certain frequency band'). I found only functions, such as 'integrate', that perform adaptive quadrature on analytic functions, and not on a curve specified as a set of (x,y) pairs. I have the

Hello, I am trying to plot a few correlograms on the same figure, with the function corrgram() from the package corrgram. However, the function does not seem to use the base graphic system, as setting out the multiple figure layout with, e.g., par(mfrow=c(2, 2,)) does not work. Does anybody know a workaround for this? Many thanks in advance for any advice best giuseppe -- Giuseppe Pagnoni,

Dear all, I am having quite a hard time in trying to figure out how to correctly spell out a model in R (a repeated-measures anova with a within-subject covariate, I guess). Even though I have read in the posting guide that statistical advice may or may not get an answer on this list, I decided to try it anyway, hoping not to incur in somebody's ire for misusing the tool. For the sake of

Dear all, I am estimating a mixed-model in Ubuntu Raring (13.04¸ amd64), with the code: fm0 <- lme(rt ~ run + group * stim * cond, random=list( subj=pdSymm(~ 1 + run), subj=pdSymm(~ 0 + stim)), data=mydat1) When I check the approximate variance-covariance matrix, I get: > fm0$apVar [1] "Non-positive definite

Dear R community, I am currently fitting non-linear models using nlm and nls. 1) I would like to compare the different models analogous to the comparison of linear models with anova(). Is there a function in R which allows to do that? 2) I would like to constrain the parameter ranges to positive values only. Is there an option in nlm or nls which allows to constrain parameter ranges? (So far I

What's the best approach to running latent class analysis with R? I've downloaded both randomLCA and poLCA packages, but I am interesting in running a standard LCA with individual records (not frequency table) as input data.

I am struggling with R code optimization, a recurrent topic on this list. I have three arrays, say A, B and C, all having the same number of columns. I need to compute an array D whose generic element is D[i, j, k] <- sum_n A[i, n]*B[j, n]*C[k, n] Cycling over the three indices and subsetting the columns won't do. Is there any way to implement this efficiently in R or should I resign to

Thanks Denis, I was looking for the option 'dns:x' in the wiki but I didn't find it. Now it works. I used    log level = 3 auth:3  dns:0 auth_audit:3 gives me unknown class message But where I can find a complete list of classes for log level? I'll also give a try on the last version of samba with json. Thanks again Giuseppe On 1/18/2018 4:52 PM, Denis Cardon wrote:

Hello, I was wondering who to contact to see about somehow interconnecting or integrating the programs R and Epi Info. I have been involved in the development of Epi Info which is a software program developed by the Centers for Disease Control and Prevention (CDC) in Atlanta (www.cdc.gov/epiinfo<http://www.cdc.gov/epiinfo>). Epi Info allows for creating data entry systems and performs

I was posed the following problem/teaser: given two matrices, come up with an "elegant" (=fast & short) function that returns a matrix with all and only the non-duplicated columns of both matrices; the column order does not matter. In essence, a matrix equivalent of union(x,y), where x and y are vectors. I could not come with anything nice. Any ideas? Giuseppe -- Giuseppe A.

Hi, I have two Samba domain controllers version 4.6.4 on Centos 7.3. I need to log every login/logout from windows PCs and I read on the wiki that I have to set log level >=3, this works. The problem is that my log.samba is filled by internal DNS messages, most of them about forwarding. in my smb.conf:         log level = 3 auth:10         vfs objects = full_audit I googled around but

the script is not complete. It isnt stopping samba and as the wiki says, DONT backup a running samba.
