Enter Meta-Analysis Data

Description

This function creates data entry object suitable for creating an object needed in the typical meta-analysis. The object will have the appropriate variable names.

Usage

EnterMeta()

Details

To create a data object appropriate for the meta-analysis functions in this package: Type
my.Meta.data <- EnterMeta()
Then use the data editor to enter data in the appropriate columns.

Value

Does not return a value, but rather is used for naming columns of a data.frame() The final object (if saved) will contain:

study	Enter Study Code or article name
Rxy	Correlation coefficient
n	Sample size for study
Rxx	Reliability of predictor variable X
Ryy	Reliability of criterion variable Y
u	Degree of range restriction - ratio of restricted to unrestricted standard deviations
moderator	moderator variable (if any)

Warning

This function will not automatically save your data object. You must create the object using the assignment operator.

Note

This is the general format required for data objects used for all the meta-analysis functions in this package. If certain variables are empty (e.g., Rxx, u), then the appropriate correction is not made, but the placeholder must be there. Moderator is useful for the user to subset the data and re-run any functions.
