I am meta-analysing some studies and drawing a forest plot for my results. However I can`t seem to get the forest plot to display the title.

An example of my code is:

require(meta)
parameter1<-metaprop(sm="PLOGIT", 
                 event=c(4,16,3,2,10,1,0,2), 
                 n=c(90,402,89,29,153,86,21,48), 
                 level = 0.95, 
                 studlab=c("study 1",
                           "study 2",
                           "study 3",
                           "study 4",
                           "study 5",
                           "study 6",
                           "study 7",
                           "study 8"), 
                 title="meta analysis 1")
forest(parameter1)

When it produces the forest plot, the title "meta analysis 1" is missing.

How can I add this in?

Thanks in advance,

Timothy
