Dear Professor King,

I was doing some literature reading and I came across your software. I try the package with my own data but I got some error.

I modified my data and make it look like the example data in the file path of the package. yourprep runs smoothly with some data like below:

dta$data$`204500`

           rspi2   popu2 time

2004          NA 4858042 1994

2005          NA 4785805 1995

2024          NA      NA 2014

2025          NA      NA 2015

But then I got error with yourcast() command.

The scripts run below:

> dta <- yourprep(dpath='./GARY_KING_CHINA_mortality',index.code="ggggaa", tag="csid",

+                 year.var=TRUE, sample.frame=c(2004,2015,2016,2025),

Error in seq.default(smpvec[ind], smpvec[ln], by = 1) :

  wrong sign in 'by' argument

Thank you for your help!
