Hi,
I'm not sure if this is a question for just the maintainer, but I'm having
issues with the pan package. Using the author's example code
*data(marijuana)
# we only use the complete data to illustrate
marijuana <- subset(marijuana,!is.na(y))
attach(marijuana)
pred <- with(marijuana,cbind(int,dummy1,dummy2,dummy3,dummy4,dummy5))
xcol <- 1:6
zcol <- 1
# Now we can fit the model.
result <- ecme(y,subj,occ,pred,xcol,zcol)*
It works just fine. But, if you comment out the third line
*#marijuana <- subset(marijuana,!is.na(y))*
I get an error
*Error in ecme(y, subj, occ, pred, xcol, zcol) :
NA/NaN/Inf in foreign function call (arg 26)*
The problem is that ecme is an imputation algorithm. But it only works if
there's no missing data on y. Is there any way around this? Or is it just a
coding error on the part of the maintainer?
Dustin
P.S. I'm using R 2.15.3 and I just installed the pan package today (version
.6)
