Methods for 'escalc' Objects

Description

Methods for objects of class "escalc".

Usage

## S3 method for class 'escalc'
x[i, ...]
## S3 replacement method for class 'escalc'
x$name <- value
## S3 method for class 'escalc'
cbind(..., deparse.level=1)
## S3 method for class 'escalc'
rbind(..., deparse.level=1)

Arguments

x	an object of class "escalc".
...	other arguments.

Note

For the `[` method, any variables specified as part of the i argument will be searched for within object x first (see ‘Examples’).

Examples

### calculate log risk ratios and corresponding sampling variances
dat <- escalc(measure="RR", ai=tpos, bi=tneg, ci=cpos, di=cneg, data=dat.bcg)

### select rows where variable 'alloc' is equal to 'random'
dat[dat$alloc == "random",]

### variables specified are automatically searched for within the object itself
dat[alloc == "random",]

### note: this behavior is specific to 'escalc' objects; this doesn't work for regular data frames
