similar to: lapack routines cannot be loaded [Help request]

Dear R-help fellows good afternoon. I am struggling in the attempt to impose some graphical conditions (changing point symbols, colors, etc) to biplot function (I am using it to visualize the results of princomp) but I can't apparently manage to change anything but the axis... and I have been browsing manuals and vignettes without finding any explicit suggestions on how to operate... Can

Hi BioC user, I have a problem extracting the gene set I would like to work with. Here is I work with my data: normData <- read.delim("normalizedData.txt",sep ="\t") ######### two class unpaired comparison # y must take values 1,2 classes <- c(-1,-2,1,2) #prepere the data for the samr analysis data.x <-as.matrix(normData[,8:11]) d=list(x=data.x,y=classes,

Thanks Andris, Michael and Petr for your prompt and kind feedbacks. I will try generating my own biplot from low-level graph commands... I hope it will work.

I installed R in (what I believe is) the standard way by adding the following line to /etc/apt/sources.list deb http://cran.us.r-project.org/bin/linux/ubuntu precise/ All was well, until I recently upgraded from 2.15.1 to 2.15.2 by running sudo apt-get update sudo apt-get upgrade Now, when I try to do simple things, I get an error. e.g. R> PP.test(rnorm(1000)) Error in

I usually ran different statistical analysis in R with routines that use lapack like gam() lm(), etc but after several updates of libraries the following error appears: library(mgcv) This is mgcv 1.7-22. For overview type 'help("mgcv-package")'. model <- with(chlaR,gam(ClorMAX ~ s(DegDay_NM))) Error en eigen(St, symmetric = TRUE) : lapack routines cannot be loaded Adem?s:

Dear all, I was willing to use the library "rgl" to plot some 3D graphics, but unfortunately, I wan't able to instal the library. The error message is below. I would be very grateful if you could give me any clues about how I can solve this.

Hi, All: What tools exist for diagnosing singular gradient problems with 'nls'? Consider the following toy example: DF1 <- data.frame(y=1:9, one=rep(1,9)) nlsToyProblem <- nls(y~(a+2*b)*one, DF1, start=list(a=1, b=1), control=nls.control(warnOnly=TRUE)) Error in nlsModel(formula, mf, start, wts) : singular gradient matrix at initial

Hello, I'm using the following for loop to find regression curves using a list of functions (formList), a list of starting values (startList), uppervalues (upperList) and lower values (lowerList). A sample of the list of function I use in the loop is the following: FormList <- list(PTG.P ~ fz1(Portata, a, b), PTG.P ~ fz2(Portata, a, b), PTG.P ~ fz3(Portata,a, b, d, e), PTG.P ~

Hi, In function chol2inv with the option LINPACK set to false (default), it raises an error when the matrix is 1x1 matrix (i.e. just a real) saying 'a' must be a numeric matrix This error is raised by the underlying C function (modLa_chol2inv in function Lapack.c). Everything is normal, but I wonder if we could have another behavior when we pass a 1x1 matrix. I spent time this morning

Hi, I'm trying to use Frank Harrell's Design:::ols function to do regression of y (numeric) on the interaction of two factors (x1 and x2), but Lapack throws an error: > library(Design) ... > load(url("http://www.csse.unimelb.edu.au/~gabraham/x")) > ols(y ~ x1 * x2, data=x) Error in chol2inv(fit$qr$qr) : 'size' cannot exceed nrow(x) = 20 > traceback()

Hi, While exploring how summary.lm generated its output I came across a section that left me puzzled. at around line 57 R <- chol2inv(Qr$qr[p1, p1, drop = FALSE]) se <- sqrt(diag(R) * resvar) I'm hoping somebody could explain the logic of these to steps or alternatively point me in the direction of a text that will explain these steps. In particular I'm puzzled

Hi, I am running simulations that does multiple comparisons to control. For each simulation, I need to model 7 nls functions. I loop over 7 to do the nls using try if try fails, I break out of that loop, and go to next simulation. I get warnings on nls failures, but the simulation continues to run, except when the internal call (internal to nls) of the chol2inv fails.

Dear all, OS: x86_64-suse-linux 9.2 CPU: Intel(R) Xeon(TM) CPU 3.20GHz R-version: R-2.1.0 I've started using a new Linux server, upgraded at the same time to R-2.1.0 (see above) and have problems with some elementary analysis that ran without a problem on my previous configuration. anova.glm gives the following error: Error in La.chol2inv(x, size) : lapack routines cannot be loaded This

Good morning to all, I am encountering a blocking issue when using the function 'breackpoints' from package 'strucchange'. *Context:* I use a data frame, 248 observations of 5 variables, no NA. I compute a linear model, as y~x1+...+x4 x4 is a dummy variable (0 or 1). I want to check this model for structural changes. *Process & issues:* *First, I used function Fstats.* It

Dear list, I am sorry to bother you with this. I just upgraded yesterday to R 2.0.0 (using apt-get under Debian Sid), and now have problems running e.g., summary(lm(...)) the lm is calculated, but the summary statement gives me the following error: Error in La.chol2inv(x, size) : lapack routines cannot be loaded In addition: Warning message: unable to load shared library

Dear helpers, I wrote a code which estimates a multi-equation model with generalized least squares (GLS). I can use GLS because I know the covariance matrix of the residuals a priori. However, it is a bit slow and I wonder if anybody would be able to point out a way to make it faster (it is part of a bigger code and needs to run several times). Any suggestion would be greatly appreciated. Carlo

Dear WizaRds, I would like to fit a curve to ten points with nls() for one unknown parameter gamma in the Kahnemann/ Tversky function, but somehow it won't work and I am unable to locate my mistake. p.kum <- seq(0.1,1, by=0.1) felt.prob.kum <- c(0.16, 0.23, 0.36, 0.49, 0.61, 0.71, 0.85, 0.89, 0.95, 1) ## how to find a function that fits these points nicely? plot(p.kum,

Hi - I am doing a monte carlo experiment that requires to do a linear regression of a matrix of vectors of dependent variables on a fixed set of covariates (one regression per vector). I am wondering if anyone has any idea of how to speed up the computations in R. The code follows: #regression function #Linear regression code qreg <- function(y,x) { X=cbind(1,x) m<-lm.fit(y=y,x=X)
