similar to: fwdmsa package: Error in search.normal(X[samp, ], verbose = FALSE) : At least one item has no variance

I'm using the fwdmsa package to identify deviant cases in a Mokken scale analysis. I've run into a problem. When I use scales comprising a few items, iI tend to get an error: Error in y[order(res[-msamp])][1:(length(samp) + 1 - length(msamp))] : only 0's may be mixed with negative subscripts I understand that the error is triggered when the algorithm is fetching cases to enter

For each zone are provided several informations in the colums from data frame: - longitude e latitude from the geografic centre - median age of houses in the zone (housingMedianAge) - total number of houses in the na zone

Dear R users, experimenting with the lm function in R, I've encountered some behaviour I don't understand with my limited knowledge of regression. I made a data-'set' of three measurements (see syntax below). Using lm (linear model) to fit the regression-line, I expected to find an intercept of 2.0 and a slope of 0, but in fact the slope is slightly below zero. Amazed by

Please help.. I have been searching for two days trying everything that I can find to solve this problem. Let's do the setup.

I'm failing to understand how getrusage() works, which is a bit perplexing, because it doesn't seem like it would be terribly complicated. I've attached the code. My aim is to verify that I can use getrusage() to do (admittedly crude) instrumentation of which functions in my program are allocating lots of memory[1]. So I figure I can call getrusage() at various points and look at

> That's one of the reasons I don't like Let's Encrypt, with one year certs it is easier to look at the certs and see what is going to expire in the coming month needing a new private key. I use dehydrated (with Cloudflare DNS challenges) and as far as I know, it seems to generate a new private key every time. All newly generated certs are generated with the timestamp in the

Seems wrong to me too, Robert. If you put your private key inside your certificate, won't it be sent to the client along with it ? Bastian, are you using an old version of thunderbird ? googling for "SSL alert number 42" gave me two results indicating a bug in thunderbird versions 31,32 and 33.

R-help readers, I''m having a problem with an R script (see below), which regularly generates the error message, Error in start:(start + (sample.length - 1)) : NA/NaN argument , for which I am unsure of the cause. In essence, the script (below) generates the start and end points for random subsamples from along a vector (in reality a transect (of a given length,

After running into several web application that rejected any e-mail address on the new gTLDs because the apps were badly written to validate with a hard-coded list of valid TLDs, I wrote a e-mail validation function that I *think* does things properly.

Hello, I am new to R and I have a question about the difference between correspondence analysis in R and SPSS.

Hello R-users, I am trying to obtain Type III SS for an ANOVA with subsampling. My design is slightly unbalanced with either 3 or 4 subsamples per replicate. The basic aov model would be: fit <- aov(y~x+Error(subsample)) But this gives Type I SS and not Type III. But, using the drop() option: drop1(fit, test="F") I get an error message: "Error in

Dear All, First of all I would like to say I do not have much knowledge about this subject, so most of you can find it really easy. I am doing a linear regression and I want to test if the slope of the curve is 0. R gives the summary statistics: Call: lm(formula = x ~ s) Residuals: Min 1Q Median 3Q Max -0.025096 -0.020316 -0.001203 0.011658 0.044970 Coefficients:

Dear all, I would like to randomly split a sample in two equally large subsamples. The sample data is stored as a matrix with each row representing an individual and each column representing some variable (e.g., name, age, sex, etc.); the first row contains the names of the variables; the first column contains the individual number (1:n, for n individuals); the number of individuals is even (so,

hi, I would like to subsample the array c(1:200) at random into ten subsamples v1,v2,...,v10. I tried with to go progressively like this: > x<-c(1:200) > v1<-sample(x,20) > y<-x[-v1] > v2<-sample(y,20) and then I want to do: >x<-y[-v2] Error: subscript out of bounds.

Dear R users, This is more a statistical question rather than an R question. I'd appreciate it if you can give me some suggestions. I have a sample of a time series (sample size 500, fat tail in density). I am trying to calculate the Standard error of standard deviation of a sub-block-sample (sample size 250). I take 100 this kind of sub-block-sample, randomly. For these 100 subsamples, I

Hello, I'm most grateful for your time to read this. I have a uber size 30GB file of 6 million records and 3000 (mostly categorical data) columns in csv format. I want to bootstrap subsamples for multinomial regression, but it's proving difficult even with my 64GB RAM in my machine and twice that swap file , the process becomes super slow and halts. I'm thinking about generating

Hey there! I got a pseudo code and don't know how to apply it to R, maybe someone can help me: Input: A dataset X, kmax: maximum number of clusters, num_subsamples: number of subsamples. Output: S(i; k) - a distribution of similarities between partitions into k clusters of a reference clustering and clustering of subsamples; i = 1 to num_subsamples Requires: T = cluster(X): A hierarchical
