Bubble plots for meta-regression models
bubble(bg, covariate, fit = TRUE, label = TRUE)A simple bubble plot in ggplot style.
Dot sizes are proportional to inverse of variance of each study (more precise studies are larger).
a baggr() model using summary-level data, with covariates
one of the covariates present in the model
logical: show mean model prediction? (slope is mean estimate of fixed_effects(), intercept is hypermean());
if you have more than two groups and the covariate is a factor, this will be ignored
logical: label study/group names?
labbe() for an exploratory plot of binary data in similar style
