[R] Metafor: How to integrate effectsizes?

Hello! I am using the metafor package for my master's thesis as an R-newbie. While calculating effectsizes from my dataset (mean values and standarddeviations) using "escalc" shouldn't be a problem (I hope ;-)), I wonder how I could at this point integrate additional studies, which only state conh

[R] How to illustrate data of a csv file as table (xtable?)

Hello! I'd like to illustrate the data of an csv file as a nice table and copy it into my word-sheet. Currently, I am trying this with the xtable () function (latex output). Example Code: dfchar <- data.frame(Author = dat$author, Year = dat$year, Age = dat$age) xtable(dfchar) Now, since there a

Re: [R] How to illustrate data of a csv file as table (xtable?)

hey guys, thank you very much for your help! Sorry for the confusion! I write my thesis in word (So it would be "word sheet" - which is obvisously not a word at all :-D sorry again), but for generating tables I use xtable () with latex output. The data for the table is stored in an excel sheet.

[R] Metafor: Strange Trim and Fill Outcome?

Hey guys, I have tested the metafor trim and fill function (y:SD, x:SMD)on my data set and yielded the following result: 1. missing studies on the right: 34 2. open circles on the rights side appear to be the number of additional effects 3. adjusted d would be higher than observed d. Since nor

[R] Metafor: forest plot for subset

Hey, I want to build a forest plot which states author and year for a subset of studies. But if I use this argument: resultREML <- rma(yi=yi, vi=vi, method = "REML", data = subset(empa, task=="x")) resultREML forest(resultREML, , slab=paste(empa$author, empa$year,sep = ",")
