Dear R users, I have two nonlinear equations, f1(x1,x2)=0 and f2(x1,x2)=0. I try to use optim command by minimize f1^2+f2^2 to find x1 and x2. I found the optimal solution changes when I change initial values. How to solve this? BTW, I also try to use grid searching. But I have no information on ranges of x1 and x2, respectively. Any suggestion to solve this question? Thanks, Kate

Hi R-users, Recently, I use maxNR function to find maximizer. I have error appears as follows Error in maxNRCompute(fn = fn, grad = grad, hess = hess, start = start, : NA in the initial gradient My code is mu=2 s=1 n=300 library(maxLik) set.seed(1004) x<-rcauchy(n,mu,s) loglik<-function(mu) { log(prod(dcauchy(x,mu,s))) } maxNR(loglik,start=median(x))$estimate Does anyone know how

Hi, My code is as the following, ratio<-seq(0,1,by=0.01) payoff<-NULL for (i in 1:length(ratio) ) { payoff1<-100*(ratio[i]>=0.7)+max(100*(1+(ratio[i]-1)*2),0)*(ratio[i]<0.7) payoff<-c(payoff,payoff1) } plot(ratio,payoff, xlab='ST/S0', ylab='Payoff',type='l') I have the discontinuous point at ratio=0.7. I do not want to have the line at 0.7, and would

Thanks Gabor and Duncan! It works. For those interested, I added this to the beginning of the \details{} section: \if{html}{\out{ <script id="MathJax-script" async src="https://cdn.jsdelivr.net/npm/mathjax at 3/es5/tex-mml-chtml.js"> </script> }} And then I can use: \if{html}{\out{\(B_{x(a,b)} = \int_0^x t^{a-1} (1-t)^{b-1} dt\)}} or

Interesting. I gave this a try, but couldn't make this work. One would have to infuse something like <script id="MathJax-script" async src="https://cdn.jsdelivr.net/npm/mathjax at 3/es5/tex-mml-chtml.js"> </script> or <script id="MathJax-script" async src="<url-to-your-site>/mathjax/tex-chtml.js"> </script> into

Hi All, After some tinkering, and with support from Duncan, I put together a package that allows for easy inclusion of MathJax equations in Rd files. The package has been submitted to CRAN, but those who want to try this out already can get it here: https://github.com/wviechtb/mathjaxr or in other words: install.packages("remotes")

Hi, I'm using the densCols function for a scatterplot and cannot figure out 1) how to extract the computed densities, and 2) how to create a legend based that represents the upper and lower ranges of the densities. For example: movers.den <- densCols(move$x, move$y) table(movers.den) #08306B #083775 #083B7C #083D7E #3989C1 #3F8FC4 28 22 101 25

Thank you. This is a very useful idea!

I have installed the kate editor on Centos 6.7 but it seems to be a very old version, 3.3.4, installed as part of kdesdk. On Centos 7 I can simply run 'yum install kate' but, alas, not on Centos 6. What is the recommended way of updating kate on Centos 6? Thank you.

About the media type, my understanding was that text was for actual text, not binary that could be decoded into text. If you think another would be more appropriate, please tell which. If it would be text/x-kate, I'd see

I'm trying to create files that contain a video stream, one or more audio streams, subtitles, and DVD-like chapter information. ATM, I use ogm containers that can handle all this. But although ogm is supported e.g. by xine (including chapters), it seems to be an unofficial hack. Is that correct? I'd like to move to ogg containers, since ogm doesn't support theora videos. My final

Hi, Actually I am facing a similar problem. I would like to fit both an ordinary (symmetric) and a non-central t distribution to my (one-dimensional) data (quite some values.. > 1 mio.). For the symmetric one, fitdistr or funInfoFun (using fitdistr) from the qAnalyst package should do the job, and for the non-central one.. am I right to use gamlss(x ~ 1, family=GT()) ? Anyway, I am a little

Dear R-users, I've recently switched to Ubuntu and I've decided to use Kate to edit my R code. I really like how Kate allows one to simply pipe their code to the terminal. However, I would find it even better if I could actually get the Kate console to display error messages (or any console outputs in fact) in red and my input in a different color. The instance of xterm that Ubuntu

hi, is there a way to make r open the help file in a separate window? i'm quite new to linux(kubuntu) and used to work with r under windows... thanks, katharina

Hello list, We have recently introduced the codecs (optional) parameter on the Ogg media types for easier identification of encapsulated codecs in conditions were it's not feasable to examine the streams directly. I received a comment from the IESG that we should have some sort of list to describe how Ogg mapping strings translate to codec parameter strings, so I went ahead and compiled a

Dear UseRs!, Everything about UseR! 2010 was terrific! I really mean "everything" - the tutorials, invited talks, kaleidoscope sessions, focus sessions, breakfast, snacks, lunch, conference dinner, shuttle services, and the participants. The organization was fabulous. NIST were gracious hosts, and provided top notch facilities. The rousing speech by Antonio Possolo, who is the chief

Hi, this patch adds: - kate support (what else) - this bumps the Javascript API to 1.1 - a few build fixes (note that the adding of -L/usr/X11/lib -lX11 looks suspect to me, that shouldn't be needed, so you may want to leave it out if you think so as well - it's odd as X11 using programs do configure fine on that box) - bad pointer dereference fix (mouse callback) - avoid the input
