Hi R users, I am trying to use the optim function to maximize a likelihood funciton, and I got the following warning messages. Could anyone explain to me what messege 31 means exactly? Is it a cause for concern? Since the value of convergence turns out to be zero, it means that the converging is successful, right? So can I assume that the parameter estimates generated thereafter are reliable MLE

Hello everyone, I was trying to do some distribution fitting with a numerical field called Tolls. The sample size = 999 rows. Basically I assigned the Toll data to a new variable K by doing: k<-dtest$Toll After that, tried to fit a gamma distribution by doing: fitG<-fitdist(k, "gamma") Then the following messages showed (oh and I checked for empty rows before doing this):

...he item does not exist, ? (uninitialized) is produced. Note that multiple value suffixes are allowed, so, for example, DagList[i](1) would produce the first operand of the i-th dag in the list. 2. Add the !getdag() bang operator. !getdag(dag, index [, default]) This bang operator produces the same result as the (...) suffix. However, the default value can be specified as the third argument. If it is not specified, ? is used. 3. Add the !setdag bang operator. !setdag(dag, index1, value1, index2, value2, ...) This bang operator creates a copy of the top-level dag node a...

I have found a strange scoping problem in Sweave. The following Rnw file doesn't produce the same output in Sweave as it does if I produce an R file using Stangle and execute that: \documentclass[12pt]{article} \begin{document} <<R>>= election <- data.frame(A=1:3, B=9:7, C=rep(0,3)) partytotal <- rep(0, ncol(election)) for (i in 1:ncol(election)) { partytotal[i] <-

Is it possible to produce the same graphic in different formats in one shot? Now if I want to produce the same graphic in pdf, ps and jpeg I run the producing code, but I change the graphic device, and I choose successively : pdf(...) ps(...) jpeg(...) So in this case I run the same code 3 times, or I have to choose a format and use converters... Is it possible to produce the 3 graphics in once

...xpressions. \begin{description} \item[binary operators] addition, subtraction, multiplication, and division use the standard $R$ syntax, although multiplication only juxtaposes the arguments. For example, {\tt a+b}, {\tt a-b}, and {\tt a/b}, produce $a+b$, $a-b$, and $a/b$, but {\tt a*b} produces $ab$. \item[unary operators] positive and negative numbers are specified with standard syntax.

Hello there, I would like to produce a plot of x<-c(4,5,6),which is the mean of each group and y<-c('groupA','groupB','groupC'). plot (x,y) can not produce any graphics because y is not numerical. What should I do to produce this graphic? Thank you in advance Lisa Wang Princess Margaret Hospital Toronto,Ca

How do I specify which option should be initially selected when using the collection_select command? I''ve tried: collection_select(:selectionfilter, :producer_id, Producer.find(:all), :id, :name, {:include_blank => true, :selected_value => @initial_selection}) However it doesn''t return the desired results (the option with the value of @initial_selection selected).

Hi, sorry for repeating the question but this is kind of important to me and i don't know whom should i ask.
