Compute effect size from Mean and Standard Error.

  grp1m,
  grp1se,
  grp1n,
  grp2m,
  grp2se,

  r,
  es.type = c("d", "g", "or", "logit", "r", "f", "eta", "cox.or", "cox.log"),
  study = NULL
)

`grp1m`	The mean of the first group.
`grp1se`	The standard error of the first group.
`grp1n`	The sample size of the first group.
`grp2m`	The mean of the second group.
`grp2se`	The standard error of the second group.
`grp2n`	The sample size of the second group.
`r`	Correlation for within-subject designs (paired samples, repeated measures).
`es.type`	Type of effect size that should be returned. `"d"` returns standardized mean difference effect size `d` `"f"` returns effect size Cohen's `f` `"g"` returns adjusted standardized mean difference effect size Hedges' `g` `"or"` returns effect size as odds ratio `"cox.or"` returns effect size as Cox-odds ratio (see `convert_d2or` for details) `"logit"` returns effect size as log odds `"cox.log"` returns effect size as Cox-log odds (see `convert_d2logit` for details) `"r"` returns correlation effect size `r` `"eta"` returns effect size eta squared
`study`	Optional string with the study name. Using `combine_esc` or `as.data.frame` on `esc`-objects will add this as column in the returned data frame.

The effect size es, the standard error se, the variance of the effect size var, the lower and upper confidence limits ci.lo and ci.hi, the weight factor w and the total sample size totaln.

If es.type = "r", Fisher's transformation for the effect size r and their confidence intervals are also returned.
