Data on effect of calcium on fasting glucose (correlated variants)
Description
Two sets of example data are included in the package: one illustrating uncorrelated variants, and the other correlated variants. These are the data on correlated variants.
Usage
calcium
calciumse
fastgluc
fastglucse
calc.rho
Format
An object of class numeric of length 6.
An object of class numeric of length 6.
An object of class numeric of length 6.
An object of class numeric of length 6.
An object of class matrix (inherits from array) with 6 rows and 6 columns.
Details
The variables calcium, and fastgluc are the genetic associations with calcium and fasting glucose for 6 genetic variants reported by Burgess et al (2015). The respective standard errors of the associations are given as calciumse and fastglucse. The matrix of correlations between the genetic variants is given as calc.rho.
These data can be used to test out the various functions in the package.
