Hi there, I was wondering if anyone could explain how you should set tol in the prcomp function. Using help(prcomp) explains it as "a value indicating the magnitude below which components should be omitted. (Components are omitted if their standard deviations are less than or equal to tol times the standard deviation of the first component.) With the default null setting, no components

Hello, I'm trying to run a lagsarlm (maximum likelihood estimation of a spatial lag model) in the spdep library ; but R gives following error message: Error in solve.default(inf, tol = tol.solve) : system is computationally singular: reciprocal condition number = 4.20137e-12 I get the same message when I try to run de lagsarlm with a bigger data set (4333 regions). The command

Martin, I fully agree. This becomes an issue when you have big matrices. (Note that there are awesome methods for actually only computing a small number of PCs (unlike your code which uses svn which gets all of them); these are available in various CRAN packages).

As I see it, the display showing the first p << n PCs adding up to 100% of the variance is plainly wrong. I suspect it comes about via a mental short-circuit: If we try to control p using a tolerance, then that amounts to saying that the remaining PCs are effectively zero-variance, but that is (usually) not the intention at all. The common case is that the remainder terms have a roughly

Hi, Does anybody know how to have output from print, without the leading [1]?

Following from the R-help thread of March 22 on "Memory usage in prcomp", I've started looking into adding an optional 'rank.' argument to prcomp allowing to more efficiently get only a few PCs instead of the full p PCs, say when p = 1000 and you know you only want 5 PCs. (https://stat.ethz.ch/pipermail/r-help/2016-March/437228.html As it was mentioned, we already

Hi, I'm using the "ncdf" library for creating ncdf files. But I need to create about 100 variables per file (e.g. single rivers), So I do not like to create each variable separately. Unfortunately I found no way to make this work, as I'm unable to create a correct list of class "var.ncdf". ###code piece river=list(mode='var.ncdf', length=nriv)

Dear gls-experts, while reading and testing some examples of the book "introductionary time series analysis with R", I encountered the following fact which puzzles me. Confidence intervals for global temperature time series (P99) computed from general least squares (GLS) to fit the time series. I repeat the example from the book and get the same results: temp.gls=gls(temp ~

Hi. Until Fedora 15, I used qsynth+Fluidsynth+alsa+biab and everything worked fine. But not anymore with Fedora 16. I can't see any midi drivers in band-in-a-box. I'm sure about my setup. Everything seems fine. I dont know which one is failing, but I suspect wine. The midi ports are ready: $ aconnect -o client 14: 'Midi Through' [type=kernel] 0 'Midi Through

I agree with Kasper, this is a 'big' issue. Does your method of taking only n PCs reduce the load on memory? The new addition to the summary looks like a good idea, but Proportion of Variance as you describe it may be confusing to new users. Am I correct in saying Proportion of variance describes the amount of variance with respect to the number of components the user chooses to show? So
