[R-meta] forest plot details

[Viechtbauer, Wolfgang (SP)]

Hi Norman,

R does not a zoom button. I suspect you are using RStudio, which has such a button. But what you really should do is save the plot using something like png() or pdf() (or whatever type of file you would like to create). You can then play around with the 'width', 'height' and 'pointsize' arguments until it looks the way you like. That way, you have full control over the dimensions and resolution of the figure. This also creates a fully reproducible workflow instead of using some tool to do screen capture.

Remember to use dev.off() when using something like png() so that the 'plotting device' is closed after you have created the figure.

Best,
Wolfgang
