The multiMiR R package and database:
Integration of microRNA-target interactions along with their disease and drug associations
(Nucleic Acids Res. 2014 Jul 24. pii: gku631)
SummarymicroRNAs (miRNAs) regulate expression by promoting degradation or repressing translation of target transcripts. miRNA target sites have been catalogued in databases based on experimental validation and computational prediction using a variety of algorithms. Several online resources provide collections of multiple databases but need to be imported into other software, such as R, for processing, tabulation, graphing and computation. Currently available miRNA target site packages in R are limited in the number of databases, types of databases and flexibility.
The R package multiMiR, with web server at http://multimir.ucdenver.edu, is a comprehensive collection of predicted and validated miRNA-target interactions and their associations with diseases and drugs.

The current version of multiMiR is 1.0.1 and can be downloaded from
multiMiR requires the XML and RCurl packages from R. The packages can be installed from R by typing:
install.packages("/pathname/multiMiR_1.0.1.tar.gz", repos=NULL, type="source")
NOTE: Change “pathname” to your own directory path.
multiMiR is distributed with a User’s Guide illustrating examples of package functions and queries.
The User's Guide can be downloaded here or viewed from R by typing:
