Yaacov,
I cannot really help you, I don't even understand what you're trying to do!
What's the link between your function and all the information you've
just sent (by the way, you forgot to send it to the list)?
By the way, attachments are not really advised, you'd better use dput()
I've never used these packages and functions, that could explain why I
don't understand.
Maybe someone else will be able to help you
Ivan

Thanks for your response Ivan. Below is the call and attached are the
referenced tables. My sense is that it's related to the table, but I'm not
quite sure why.
library(statmod)
library(rgenoud)
aE<- read.table("Z:\\Measurement Grant\\TCC linking\\f1p1.dat",
header=T,sep="\t")$mean[1:20]
bE<- read.table("Z:\\Measurement Grant\\TCC linking\\f1p1.dat",
header=T,sep="\t")$mean[31:50]
cE<- rep(0,25)
aB<- read.table("Z:\\Measurement Grant\\TCC linking\\f1p28.dat",
header=T,sep="\t")$mean[1:20]
bB<- read.table("Z:\\Measurement Grant\\TCC linking\\f1p28.dat",
header=T,sep="\t")$mean[31:50]
cB<- rep(0,25)
theta<-seq(-4, 4, length=20)
nxi<- 40
std<- sqrt(c(0.306))
item<- c(9,8)
ax<-aB
cx<-cB
bx<-bB
ay<-aE
cy<-cE
by<-bE
testlet.linking.coefficients(ax, cx, bx, theta, nxi, std, item, ay,
cy, by,"Z:\\Measurement Grant\\TCC linking\\f1P28p1OUT.txt")

Hi,
Maybe knowing what you provided to the function call as a, b, c, and xi would
help!
Since you're at it, think about using the dput() function to provide
copy/pastable objects ;)
HTH,

Greetings,
I am a very novice user with R, and in the course of running a linking
procedure :
P.old<- function (a, c, b, xi){
#a contains a parameters
#c contains c parameters
#b contains b parameters
#xi is a one column vector containing quadrature
points for xi(=theta-gamma)for one item
tmp<- a*(xi-b)
p<- c+(1-c)*pnorm(tmp)
return(p)
}
I receive an error which states:
Error in P.old(a[i], c[i], b[i], node) :
dims [product 40] do not match the length of object [0]
I'm not exactly sure to what I should attend in changing the code. Any help
would be greatly appreciated!
