funnel() axis label

[wviechtb]

Hi Dan,

Nice tutorial! One thing: You use funnel() with xlab = "Correlation coefficient", but since you are analyzing r-to-z transformed correlations, the values on the x-axis correspond also correspond to r-to-z transformed correlations. You can also use atransf = transf.ztorr in funnel() in which case the x-axis would correspond to (raw) correlation values. The labeling of the x-axis should actually be handled automatically by the funnel() function, so unless you have good reasons for doing so, there is no need to adjust the xlab argument.
