[R-meta] Funnel plot from data frame

[meta at frankbosco.com]

Greetings to all,

 

I am building an R Shiny application that will display several funnel plots
made in metafor. The plots are created within a large, custom function and
all are saved in an R list. However, when I try to reproduce any of the
plots, a data.frame is returned (and not the plot).

 

In R, imagine the following two plots saved into a list:

 

#############################################

#Initialize list

   plotList <- list()

 

#Save 1st plot as list element 1

   plotList[1] <- funnel(data1, main = "Funnel for data1")

 

#Save 2nd plot as list element 2

  plotList[2] <- funnel(data2, main = "Funnel for data2")

#############################################

 

When I run plotList[1], I don't get the plot. I get a data.frame on which
the plot relies.

 

My question: Is there any way to return the plot itself or reproduce the
plot based on the saved data.frame (without saving the plot as an image
file)?

 

Thanks,


Frank
