[R] dims error

[Ivan Calandra]

  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,
Ivan
