Hi. The local below comprises of observation values within a variable "Disease". I am to merge two datasets only for the observation values mentioned in the local. However, the code in the loop deletes each disease case/observation value in the local before running the next. So, instead of getting a new dataset which has merged values for all the observation values in "classList", I only get a dataset merged for the last observation value "Cancer, solid, unspecified". What am I missing here? Any help would be much appreciated. Thanks.
Code:
clear
#delimit ;
local classList
Asthma
"Pain, nociceptive, general"
"Cancer, unspecified"
"Hypertension, unspecified"
"Inflammatory disease, unspecified"
"Cancer, breast"
"Infection, HIV/AIDS"
"Diabetes, Type 2"
"Arthritis, rheumatoid"
"Cancer, solid, unspecified"
;
#delimit cr
foreach class of local classList {
use "${datadir}\Pharmaprojects_Disease_reshaped", clear
keep if Disease == "`class'"
merge 1:m DrugNameX using "${datadir}\Pharmaprojects_DevelopmentStage_step1", keep(match)
save "${dodir}\Disease+Stage", replace
}
