Pheno2geno is an R package to create genetic maps out of phenotype expression data. Currently supported breeding schemes are: Recombinant Inbred Lines (RIL), F2 and backcross (BC). The master branch is the current stable version and is tagged. The master branch can be installed into R, development branches may contain errors.
Optional: RankProd package from www.bioconductor.org
The easiest way is to use package devtools. Type in R:
install.packages("devtools") library(devtools) install_github(repo="phenotypes2genotypes",username="KonradZych") library("pheno2geno")
Load the library in the R interface by the following command (in R):
You can always access the help files of the package or for any function by typing:
To read in data files, use the read.population function:

Clone a local version of the Github repository to your own hard disk:
git clone git://github.com/KonradZych/phenotypes2genotypes.git
Install it from the commandline by using the following command:
R CMD INSTALL phenotypes2genotypes
Then start R and load the library to make the functions available:
Modify some code. (Search -> 'TODO')
