Documenting R package with Rd file
I have trouble documenting an R package. In my .Rd file (sixth line below), I have
uhat<-m%*%y
but when the package is built (successfully), the matrix multiplication part does not show up in the documentation. The line become (missing %*% y)
uhat<-m

\examples{
x<-c(1,2,3,4,5)
y<-c(1,1,2,2,4)
x<-cbind(1,x)
m<-mmat(x)
uhat<-m%*%y
dstat(uhat)
}
