[R-meta] Error Stopped because k = 0 after sub setting​.

[Klaow sota]

Dear Michael,

Thank you so much for your suggestions.
I attached the data(details of my analysis) below.
yi and vi needed to run for rma. However, I got that error message as I mentioned in the previous email.

# fit random-effects model in the three subgroups
res.s <- rma(yi, vi, subset=(interven=="PZQ"),data=dat)-->Got error
->Error: Stopped because k = 0 after subsetting.
res.r <- rma(yi, vi, subset=(interven=="Integrated"),data=dat)-->Got error
res.a <- rma(yi, vi, subset=(interven=="Health Ed"),data=dat)-->Got error

# add summary polygons for the three subgroups

addpoly(res.s, row=18.5, cex=0.90, atransf=exp, mlab=mlabfun("RE Model for Subgroup", res.s))
addpoly(res.r, row= 7.5, cex=0.90, atransf=exp, mlab=mlabfun("RE Model for Subgroup", res.r))
addpoly(res.a, row= 1.5, cex=0.90, atransf=exp, mlab=mlabfun("RE Model for Subgroup", res.a))

Is it error source of yi or vi? How should I solve this problem? Should I cut some data?

Best,
P SOTA

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"?
