.
## S3 method for class 'list.rma' as.data.frame(x, ...) ## S3 method for class 'list.rma' as.matrix(x, ...) ## S3 method for class 'list.rma' x[i, ...] ## S3 method for class 'list.rma' head(x, n=6L, ...) ## S3 method for class 'list.rma' tail(x, n=6L, ...) ## S3 replacement method for class 'list.rma' x$name <- value

For the `[`
method, any variables specified as part of the i
argument will be searched for within object x
first (see ‘Examples’).

### copy data into 'dat' and examine data dat <- dat.viechtbauer2021 ### calculate log odds ratios and corresponding sampling variances dat <- escalc(measure="OR", ai=xTi, n1i=nTi, ci=xCi, n2i=nCi, add=1/2, to="all", data=dat) ### fit mixed-effects meta-regression model res <- rma(yi, vi, mods = ~ dose, data=dat) ### get studentized residuals sav <- rstudent(res) sav ### studies with studentized residuals larger than +-1.96 sav[abs(sav$z) > 1.96,] ### variables specified are automatically searched for within the object itself sav[abs(z) > 1.96,] ### note: this behavior is specific to 'rma.list' objects; this doesn't work for regular data frames
