Dear Klaow, You now that R is case-sensitive? That is, see the following: # Set interven <- "pzq" # Then interven=="pzq" # provides [1] TRUE # However, interven=="PZQ" # provides [1] FALSE That is, you have to spell the values in the code exactly as spelled in the data set.

I curious that yi/vi probably get problem and made the error happened.

Dear Klaow Without your data it is hard to be sure. I assume you have checked that the variable interven does indeed contain some values "PZQ"?
