meta2DF.metacont: Convert 'metacont' Objects into Data Frames

In pmur002/metaplot: Meta-analysis Forest Plots

Description

A function that turns objects of class 'metacont' into a list of data frames used for plotting.

Usage

## S3 method for class 'metacont'
meta2DF(meta, add = NULL, rowOrder = NULL, title = NULL,
                           subtitle = NULL, ...)

Arguments

meta	An object of class 'metacont'.
add	List of vectors that can be added as columns to the data frame with corresponding values to each study row.
rowOrder	Column name to order rows of studies by.
title	Title of the meta-analysis to be shown on top of the plot.
subtitle	Subtitle of the meta-analysis to be shown under the title.
...	Further arguments from order.

Details

In order to produce the plot, metaDF2Matrix.metacontDF must be called after producing the 'metacontDF' object from this function. The data frame columns can be selected and ordered using metaDF2Matrix.metacontDF.

Value

An object of class c('metacontDF','metaDF') with a list of following components:

DF	A data frame with studies as rows and study attributes as columns.
summaryFixed	A data frame with attributes of fixed effects model. See forestDF.
summaryRandom	A data frame with attributes of the random effects model. See forestDF.
hetero	Statistical results from the input 'metacont' object. See metacont.
title	Title of the meta-analysis.
subtitle	Subtitle of the meta-analysis.

Examples

### single group
library(meta)
data(Fleiss93cont)
meta1 <- metacont(n.e, mean.e, sd.e, n.c, mean.c, sd.c,
                  data = Fleiss93cont, sm = "SMD")
Data <- meta2DF(meta1, title = "Mental Health Treatment",
                rowOrder = "effect", decreasing = TRUE)
### grouped studies
library(meta)
data(Fleiss93cont)
meta <- metacont(n.e, mean.e, sd.e, n.c, mean.c, sd.c,
                 data = Fleiss93cont, sm = "SMD",
                 byvar = c(1,2,1,1,2), bylab = "group")
Data <- meta2DF(meta, title = "Mental Health Treatment",
                rowOrder = "effect", decreasing = TRUE)
