Examples

### copy data into 'dat'
dat <- dat.bcg

### calculate log risk ratios and corresponding sampling variances
dat <- escalc(measure="RR", ai=tpos, bi=tneg, ci=cpos, di=cneg, data=dat)

### fit random-effects model
res <- rma(yi, vi, data=dat)

### get 95% CI for tau^2, tau, I^2, and H^2
sav <- confint(res)
sav

### turn object into a regular data frame
as.data.frame(sav)

### copy data into 'dat'
dat <- dat.berkey1998

### construct block diagonal var-cov matrix of the observed outcomes based on variables v1i and v2i
V <- vcalc(vi=1, cluster=author, rvars=c(v1i, v2i), data=dat)

### fit multivariate model
res <- rma.mv(yi, V, mods = ~ outcome - 1, random = ~ outcome | trial, struct="UN", data=dat)

### get 95% CI for variance components and correlation
sav <- confint(res)
sav

### turn object into a regular data frame
as.data.frame(sav)
