In dSimer: Integration of Disease Similarity Methods

#' Integration of Disease Similarity Methods
#' 
#' dSimer is an R package which provides computation of nine 
#' methods for measuring disease-disease similarity, including a 
#' standard cosine similarity measure and eight function-based 
#' methods. The disease similarity matrix obtained from these nine 
#' methods can be visualized through heatmap and network. Biological 
#' data widely used in disease-disease associations study are also 
#' provided by dSimer.
