Re: [R] Linear optimization with quadratic constraints

I did't really feel like digging through your HTML-contaminated email [1] that has nothing concrete in it, most notably R code and input data, nor an expected result that the code should yield. (Before you protest that you are LOOKING for R code, please go read about reproducible R examples

Re: [R] About populating a dataframe in a loop

Hello, I believe you should follow Jeremiah's sugestion to first read all csv files into a list and then rbind them. Something like the following. file_list <- list.files(pattern = "*.csv") df_list <- lapply(file_list, read.csv) result <- do.call(rbind, df_list) Hope this helps, Rui

[R] recoding responses in a numeric variable

Hello, I am working with a dataset in R studio, and I have created a numeric variable which I have called fear by using a factor variable (called vn35). Here is the piece of code: fear<-gles_reduced$vn35 levels(fear) table(fear, as.numeric(fear), exclude=NULL) Then I have coded the levels "don't

Re: [R] which parallel routine

There is always overhead in starting and stopping parallel processes, but the "per subject terms ... slow and complex" suggests to me that this is already a small price. Mcapply tends to be good when you need to share a lot of the same data with all processes and have many processors with

[R] which parallel routine

I'm looking for advice on which of the parallel systems to use. Context: maximize a likelihood, each evaluation is a sum over a large number of subjects (>5000) and each of those per subject terms is slow and complex. If I were using optim the context would be fit <- optim(initial.values,

Re: [R] testing whether clusters in a PCA plot are significantly different from one another

Significance tests for group differences in a MANOVA of lm(cbind(pc1, pc2) ~ group) will get you what you want, but you are advised DON'T DO THIS, at least without a huge grain of salt and a slew of mea culpas. Otherwise, you are committing p-value abuse and contributing to the notion that

Re: [R] What is c1 file and how to open it (.c1) in R program?

There is no guarantee that a filename having a particular extension has any particular format inside it. You can make guesses and hope they are right, but the only dependable way to know what format is inside is to receive communication from the author about it or open it in a text or binary
