Hello, Try the following. library(reshape2) # Don't need 'cbind' mat - data.frame(sp1=c(rep(0, 5), rep(1, 5)), sp2=sample(c(rep(0, 6),rep(1, 4))), fac=c(rep(a, 3), rep(b, 3), rep(c, 4))) mat.new - matrix (c(0, 1, 1, 1, 1, 1), nrow=2, ncol=3) rownames(mat.new) - c(sp1, sp2)

[R] (Slight) calculation discrepancy in escalc (metafor package)

Hello, I recently started using the metafor package (version 1.6-0) in R (2.15.1, 64-bit Windows 7) and noticed that I was getting slightly different values when I manually calculated the standardized mean difference versus what escalc was giving me. Here's a very simple example:

[R] Irregular splits in dataframe

Hello, Re framing my previous question, my dataframe (Soil Type) looks something like below. I want the code to find / first and split the string into 2 or 3 depending on the number of /. I don't want to specify the number of columns after split. How can I do that ? Granitic Hills 16-20 PZ

Re: [R] (Slight) calculation discrepancy in escalc (metafor package)

The pooled standard deviation is calculated exactly how you describe it. There are, however, two differences between your approach and the way escalc() computes the SMD and corresponding sampling variance: 1) Instead of the equation for approximating the correction factor (J), escalc() uses
