Subject: st: Keep string data
Hi statalisters,
I have a dataset that contains information on the number of
registrations within a certain year for different cancer sites. The
variable name is siteterm and is stored at string10 type. When I am
analysisng the data I need to keep and drop certain cancer sites
however I am having trouble doing this. I have no problem dropping
variables that are stored as int and byte types for example
keep if year==1996
but when I try to do the following
keep if siteterm==lung
I have the error "lung not found; r(111)" returned.
Any advice would be appreciated as this is the last stumbling
block I am having in relation to my project.
Thanks in advance,
Christopher D Fergusson
