Very concise and easy to follow. I had to pause at times to figure out how to adjust the codes [for calculating the effect sizes] for the type of data I'm using. However I was able to keep up with this tutorial. Thank you

I'm glad it was helpful! You may have found this already, but just in case you didn't, here's the documentation for escalc() that describes different effect size calculations: wviechtb.github.io/metafor/reference/escalc.html

Thank you Dr. Noah. I just tried to use the escalc function, however, the reply from the R is Error in escalc(measure = "SMD", m1i = AAGmean, sd1i = AAGstd, n1i = AAGnumber, : could not find function "escalc". Is there any miss from my formula? Thank you

If you're getting the error saying it could not find escalc(), my guess is that you may have forgotten to load the metafor package (which happens to all of us from time to time, as it is easy to overlook on accident!) If you have never installed metafor, you need to install it first. The code would be: install.packages("metafor") Each time you open the R session, you'll need to load metafor. This is the step it seems like you may have missed on accident. This should be run before running using the escalc() function The code for that would be: library(metafor) Regarding your escalc() code, it does seem incomplete, but that may be from copy-pasting the error code. My best guess is you may have forgotten to load the metafor package library, so I would start there.
