steroids: Steroid data

Description

Steroid data. Between 42 and 61 atoms for each of 31 steroid molecules.

Usage

data(steroids)

Arguments

Format

steroids$x : An array of dimension 61 x 3 x 31 of 3D co-ordinates of the 31 steroids. If a molecules has less than 61 atoms then the remaining co-ordinates are all zero.

steroids$activity : Activity class (`1' = high, `2' = intermediate, and `3' = low binding affinities to the corticosteroid binding globulin (CBG) receptor)

steroids$radius : van der Waals radius (0 = missing value)

steoirds$atom : atom type (0 = missing value)

steroids$charge : partial charge (0 = missing value)

steroids$names : steroid names
