In ChemmineR: Cheminformatics Toolkit for R

Description

Imports one or many molecules from an SD/MOL file and stores it in an SDFset container. Supports both the V2000 and V3000 formats.

Usage

read.SDFset(sdfstr = sdfstr,skipErrors=FALSE, ...)

Arguments

sdfstr	path/name to an SD file; alternatively an SDFstr object can be provided
skipErrors	If true, molecules which fail to parse will be removed from the output. Otherwise and error will be thrown and processing of the input will stop.
