R help - Jun 2003 - Hmisc multiple imputation functions

Dear all;

I am trying to use HMISC imputation function to perform multiple imputations 
on my data and I keep on getting errors for the code given in the help 
files.

When using "aregImpute" the error is;
>f <- aregImpute(~y + x1 + x2 + x3, n.impute=100)
Loading required package: acepack
Iteration:1 Error in .Fortran("wclosepw", as.double(w), as.double(x), 
as.double(runif(lw)),  :
        C/Fortran function name not in load table

When I use "transcan" it is;
>f  <- transcan(~y + x1 + x2, n.impute=10, shrink=FALSE)
Error in transcan(~y + x1 + x2, n.impute = 10, shrink = FALSE) :
        Must specify data= when using R

I am not sure what I am missing.

You did not specify the version of Hmisc nor the output of the version command
to provide the OS and version of R.

Please see above.  If you are running under Windows, perhaps the wclosepw
routine was omitted from the Windows distribution of Hmisc.

That is an error in the documentation which I just fixed.  Add

 d <- data.frame(y,x1,x2)
 f <- transcan(~y+x1+x2, ......., data=d)
