Re: [R] Memory usage reported by gc() differs from 'top'

[R] mixed effects meta-regression: nlme vs. metafor

ts belong to the same study, i.e., have a common random effect. What I am missing is an equivalent to the "random" statement in the "lme()" command above. Adding an option like "slab=as.character(dat$study)" only seems to affect the labeling but not the actual computation.
