Help for reading in "nlswork5_xtrccipw" dataset

[Anne Grossestreuer]

I am potentially interested in using the package "xtrccipw" to perform pattern-mixture analysis on longitudinal data and want to work through some examples. The examples are all from the "nlswork5_xtrccipw" dataset, with code to build in the appendix here: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5947963/. When I cut and paste the code (from the pdf, the website, and ePub), I get the error "` invalid name
r(198);" after the below chunk of code:

foreach outcomevar in union {
generate _firstyearRD1`outcomevar´ = (`outcomevar´ < .)
generate firstyearRD1`outcomevar´ = .
replace firstyearRD1`outcomevar´ = _firstyearRD1`outcomevar´ ///
if (yearidx == 1)
replace firstyearRD1`outcomevar´ = ///
_firstyearRD1`outcomevar´ * firstyearRD1`outcomevar´[_n−1] ///
if (yearidx > 1)
drop _firstyearRD1`outcomevar´
rename firstyearRD1`outcomevar´ RD`outcomevar´
replace `outcomevar´ =. if (RD`outcomevar´ == 0)
}

I do not want to alter the dataset because I want to use it to learn - does anyone know what is causing this error and how to fix?

Thank you very much,
Anne

There seems to be an issue with your rightmost macro quotes. This could be caused by copying to a text editor, or it might be related to how they are rendered in the PDF document. Try the following:

foreach outcomevar in union {
generate _firstyearRD1`outcomevar' = (`outcomevar' < .)
generate firstyearRD1`outcomevar' = .
replace firstyearRD1`outcomevar' = _firstyearRD1`outcomevar' ///
if (yearidx == 1)
replace firstyearRD1`outcomevar' = ///
_firstyearRD1`outcomevar' * firstyearRD1`outcomevar'[_n−1] ///
if (yearidx > 1)
drop _firstyearRD1`outcomevar'
rename firstyearRD1`outcomevar' RD`outcomevar'
replace `outcomevar' =. if (RD`outcomevar' == 0)
}
