MDmerge: Merge Two or More MDlists

In trinker/metaDAT: Tools for Data Management in Meta-Analysis

Description

Merge two or more MDlists.

Usage

  MDmerge(..., id.vars = NULL, sep = "_",
    detect.class = TRUE, stringsAsFactors = FALSE)

Arguments

...	MDlists (objects from read.MD) to be coerced to one.
id.vars	Specifications of the common variable(s). Default is NULL.
sep	A character string to separate the MDlist merged study names by + identifiers (id.vars).
detect.class	logical. If TRUE detects the class of the character string(s) for each variable.
stringsAsFactors	logical. Should character vectors be converted to factors if detect.class is TRUE?

Value

Returns a merged MDlist object.

Note

General use is for merging multiple coders with different studies together into one MDlist. This is not recommended for combing the same studies coded by two different coders (double coded). Instead keep two different MDlist data sets for reliability checking.

datMerged <- MDmerge(dat2, dat1)

MDstr(datMerged)
names(datMerged)
MDmerge(dat2, dat1, id.vars = c("coder", "time"), sep = "%")
