The function states compute effect size from Point-Biserial Correlation, thus, the effect-size r
is the input, not the output.
In the arguments section under esc_rpb, it lists r as an output type under es.type. In the linked webpage calculator, you can enter the r and n and it gives you back out the r and range and variability. I wanted to get the standard error of the correlation coefficient, so I was using this function with r and n as inputs, hoping to get r and se as outputs. Is there another function that does this, which more closely mirrors that of the webpage (r into r, with standard error, based on sample size)?
It says on the documentation that for esc_rpb I can ask it to give me the effect size r in the output. When I try it, it says that is has to be any of the other types listed (d, g, logodds, etc). the default for it seems to be to spit out a cohen's d, which isn't what I thought the default would be. either way, it'd be nice if it would allow me to get output with the effect size as an r.
