[R] What does it mean by initial value not available?

Dear friends. I use ConstrOptim( ) and got error message initial value not available. My understanding of initial value not available is that one of the following 3 cases happens: 1.The objective function is not well defined at the point of the initial value. 2. The differentiation of the

[R] artificial data matrix with 100000 rows

Hi guys, I tried to made the matrix with this size by either matrix() or array(). However, there seems to be default limit of number for rows made. I got sort of error message from R .To be specific, m--matrix(ncol=3,nrow=10) error message:[ reached getOption(max.print) -- omitted 7

[R] Sweave figure aspect ratio

Hello, using Sweave, is there any option to preserve the original aspect ratio of plots generated from R code? Consider this Sweave chunk: test,echo=F,fig=T,width=2,height=2= x - 1:10 y - sin(x) par(mar=c(4,4,0,4)) plot(x,y, xlab=x label, ylab=y label ) @ In Latex, I want to

Re: [R] Problem in installing packages on linux machine...

Your problem is not related to missing file permissions but to a problem with the linker (ld). As you can see from the error message, ld cannot find a compatible libR.so so compilation fails. You did not specify which architecture you're on but in case it is a 64-bit platform, the following thread

[R] NA in AR model residuals

Hi, This may be a stupid question, but why when creating an AR model, why does R set the first n components of the ar object's resid vector to NA (where n is the order of the model)? Regards, NC [[alternative HTML version deleted]] __

[R] loop execution problem

This is bizzare. The for loop I set seems to go infinitly because the hourglass cursor never disappers and I never get the result. But when I click on X of the window try to exit R, the execution finishes right after I abort exiting when RGui asks me to save the workplace or not. Please help

I assume that you want to do the fitdistr on one of the columns of the dataframe that you have read in. What does 'str(ONES3)' show? If the data is in the first column, try: fitdistr(ONES3[[1]],chi-squared) On 9/9/07, Terence Broderick [EMAIL PROTECTED] wrote: I am trying to fit the

Dear Professor Mordoch. Thank you very much for your help! Your time is highly appreciated! I do intend to optimize over 3 parameters and the way I did it is constrOptim(c(0.5,0.3,0.5), fit.error, fit.error.grr, ui=ui,ci=ci). Also, There is a missing value for both sigmae and ss. (The last 3rd

Re: [R] Sweave figure aspect ratio

Many thanks for the quick reply, Duncan. Now I see that something is going wrong in R already. I overlooked this because the R window was so big. I have to persuade plotViewport() not to create a square area but one which takes the different margins into account. Best regards, Werner ---
