[R-meta] meta-analysis of data summarised as means and SD

[mark walton]

Hi
I wonder if anyone can suggest a way of looking at the impacts of various
factors (eg habitat, climatic zone, analysis method, minimum particle
detection size) on the sampled microplastic densities? My data is already
summarised as mean and SD for each study.
I was using the "metamean" package but this can only look at a single
factor at a time.
Thanks
Mark
