Hello R people! How can one use a for loop (or something similar) in R? As I type in each line, I get syntax errors... I'm just confused how much to type in at each ">" prompt.

Dear all, I need to maximize the v: v= D' W D D is a column vector ( n , 1) W is a given matrix (n, n) subject to: sum D= 1 (BTW, n is less than 300) I´ve tried to use maxBFGS, as follows: ##################################### objectiveFunction<-function(x) { return(t(D)%*%W%*%D) } Amat<-diag(nrow(D)) Amat<-rbind((rep(-1, nrow(D))), Amat) bvec<-matrix( c(0), nrow(D)+1,

Hello useRs, I`m running structural equation models with R, but for one of my models the below error message apears. I`m trying to change startvalues but without success. The manual for sem package did not help me. Does anyone knows how to change startvalues for iteration in sem package? Or it can be another problem with the model? Error in startvalues(S, ram, debug = debug, tol = start.tol)

Dear All, I was trying to call a self-defined function that performs nonlinear regression and gets the corresponding prediction upper limit using nls2 package. However, weird thing happened. When I called the function in the main program, an error message "fitted(nlsmodel): object 'nlsmodel' not found" came up. But when I directly ran the codes inside the function, no error came

Hello, i know that i have to use optim, but i'm confused how its possible maximize the sum over all l[i] and get the optimized max(LL), r and alpha? LL <- function(trans,time){ for(i in 1:length(trans){ l[i] <- log(lgamma(r+trans[i] - gamma(r+1)*(alpha/alpha+t[i]))**r)*(t[i]/alpha+t[i]))**trans[i] } return(sum(l)) } i'm confused how i have to set r and alpha and i

After compiling and installing ssh-1.2.2 at home whenever I try to ssh to a host ssh freezes and never actually tries to establish a connection. Actually it depends on whether I'm dialed in or not (it has to do with dns lookups, I'm not sure exactly what it is doing). The problem seems to be caused by getaddrinfo in ssh.c, line 511. If I strace the process it keeps trying to connect to

Greetings... I'm struggling trying to set up a samba 3.0.23c PDC with ldap backend. The server is Fedora 5, OpenLdap version 2.3.19-4. I've got it so smbd and nmbd start properly and I can use a windows box and see the domain using srvmgr.exe and usrmgr.exe. I'm then able to signon from a windows XP computer with the command net use \\pdcserver\ipc$ /user:root rootpassword Some

Hi, I installed the package Hmisc with the command install.packages("Hmisc") without errors.

Aside from the fact that you're checking for i64 specifically instead of generally checking for illegal types, how much of this is really PPC specific? Would this be a reasonable enhancement to the SDAG logic in general? -Hal On 1/4/19 8:03 AM, Nemanja Ivanovic wrote: The changes seem fine to me.

Sorry if this question is more for the LDAP community, but since I ran into this via the Samba3 by Example book, I'm asking here. :) As described in Chapter 6, PAM and NSS Client Configuration, in the ldap.conf file, is it necessary to have the bindpw line? From what I have seen, ldap.conf needs to be world readable and having that entry would seem to me to be a security risk. Am I

Hello- If I input a variance-covariance matrix and specify NA for start values, how does sem determine the start value? Is there a default?

Hello, I finally run my measurement model in sem - successfully. Now, I am trying to print out the path diagram that is based on the results - but for some reason it's not working. Below is my script - but the problem is probably in my very last line: # ANALYSIS OF ANXIETY, DEPRESSION, AND FEAR - LISREL P.31 library(sem) # Creating the ANXIETY, DEPRESSION, AND FEAR intercorrelation matrix

Hi, I am running a simple linear model with (say) 5 independent variables. Is there a simple way of getting the variance-covariance matrix of the coeffcient estimates? None of the values of the lm() seem to provide this. Thanks in advance, Ritwik Sinha rsinha@darwin.cwru.edu Grad Student Case Western Reserve University [[alternative HTML version deleted]]

Hi Folks, There has been past correspondence regarding Catherine Loader's Bell Labs (oops, Lucent) paper "Fast and Accurate Computation of Binomial Probabilities" which gives the algorithm on which R's dbinom() is based.
