Ave_func: Optimizing data from UK Biobank

In RVIpkg: Regional Vulnerability Index

Optimizing data from UK Biobank

Description

The Ave_func() can optimize data from UK Biobank(UKB). It will rename field IDs of regional neuroimaging traits to abbreviation names, and then average data of left and right hemispheres of the same field.

Usage

Ave_func(resp.range, type = "all", data)

Arguments

resp.range	a numeric vector specifying column range of regional neuroimaging traits.
type	a character string specifying data types of regional neuroimaging traits(i.e. All traits(type='all'), White matter(type='WM'),Gray matter(type='GM') or Subcortical(type='Subcortical'))
data	a data frame contains regional neuroimaging traits with field IDs from UKBB. Default(type='all')

Value

a dataframe of regional neuroimaging traits with abbreviated field names.

Note

The Ave_func() function is developed at the Maryland Psychiatric Research Center, Department of Psychiatry, University of Maryland School of Medicine. This project is supported by NIH R01 EB015611 grant. Please cite our funding if you use this software.
