Hi! I can compile R on macOS with standard BLAS but how can I compile R myself to get this vecLib BLAS which is added in binary distribution for Mac on CRAN? regards, Tomek. [[alternative HTML version deleted]]

Is there a simple method under R to solve an overdetermined system of linear equations Ax=b with A being a matrix m*n? I know that solve() seems to work for m*m matrices, but I had no luck...

Dear R developers and users! I have calculated metric MDS by cmdscale from matrix of distances (dissimilarities). I would like to ask you how can I estimate how well this new mapping represents characteristic features of my data set? Thank...

Hi, I have data in form: label, x, y. How can I make a scatter plot from the data, so that the label will be just next to the x, y point? Tomek -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read http://www...

I'm a bit ashamed, because it actually works, but I'd some problems with the privilages because it is not working when I set wd to c:\, when I changed I used default wd everything is working. Thanks for...

Hi, I want to perform goodness of fit test for multinominal distribution. The easiest way would be to use Chi2, but the measurment errors are not normally distributed. I thought about using some bootstraping method to perform the analysis. How...

Hi, I can't save a plot in R. Even the most simple examples taken from the internet doesn't work: jpeg('rplot.jpg') plot(1:10) dev.off() The message that I receive is: "> jpeg('rplot.jpg') > plot(1...

lm.fit(A, b)$coefficients seems to do what I want, but, as you have rightly pointed out, the deviations most probably will not have constant variance (but should be normally distributed). Basically, I make measurements from which I obtain...

Hello! My three Groschen: On MacOS (Intel CPU) and R 4.4.3 I report: > dput(.Machine$double.xmax, control = 'hex') 0x1.fffffffffffffp+1023 > dput(sqrt(.Machine$double.xmax), control = 'hex') 0x1.fffffffffffffp+511 > dput(sqrt(.Machine$double.xmax)^2...

Dear Stephen, Thanks a lot! now I see that cmdscale is not the best option for my problem So I am wondering if you can advice me other method of MDS or different approach to my problem: I have matrix...

Thank you Simon! configure with this option seems to work fine and produce: "External libraries: pcre2, readline, BLAS(Accelerate), curl Additional capabilities: PNG, JPEG, TIFF, NLS, cairo, ICU Options enabled: framework, shared BLAS, R profiling" However after starting compilation I...
