Hi Myungjin, The funnel plot is no more than the precision of the estimates of related studies plotted against the estimates. That is, if your measure of precision is the sample size (SS) and the estimate is named E,
plot(E,SS) Look at the metafor package for good funnel plot functions. Egger's test can be misleading, see: https://training.cochrane.org/resource/identifying-publication-bias-meta-analyses-continuous-outcomes for a good introduction. Jim produces a very basic funnel plot. Enclosing lines or curves are usually added, forming the inverted "funnel".
