There are at least three packages available from CRAN (meta, metafor, 
rmeta) which draw forest plots so it would help us if you had told us 
which one you are using.

Are you really using a forest plot for a meta-analysis or for some 
other purpose?

It would be unusual to have a meta-analysis with so many studies 
included so I assume you are doing something else.
