# funtooNorm [![Build Status](]( The R package ```funtooNorm``` provides a function for normalization of Illumina Infinium Human Methylation 450 BeadChip (Illumina 450K) data when there are samples from multiple tissues or cell types. ## Installation options Install from bioconductor ```shell if (!requireNamespace("BiocManager", quietly=TRUE)) install.packages("BiocManager") BiocManager::install("funtooNorm") ``` Download the current build <a href="" ><b>here</b></a> and install it with ``` shell $ R CMD INSTALL funtooNorm_1.00.1.tar.gz ``` Or, if you want to build from source, you can also install from GitHub using the [devtools]( package in `R`: ```r library(devtools) install_github('GreenwoodLab/funtooNorm', local=TRUE, build_vignettes = TRUE) ``` If you have difficulties with the function ```install_github``` you can download and install from source using the commands ```R CMD build``` and ```install```: ``` shell $ git clone $ R CMD build ./funtooNorm $ R CMD INSTALL funtooNorm_1.00.1.tar.gz install_github('greenwoodLab/funtooNorm') ``` ## Usage There are two functions in the package, ```funtoonorm``` and ```agreement```. The output of ```funtoonorm``` is two matrices: both a normalized methylation data set of beta values and also raw, non-normalized beta values. As an input, the user needs to provide signal A and signal B matrices of data extracted from Illumina IDAT files, as well as control probes signals. The function also requires a list of cell types or tissues. Besides its main purpose of normalization, ```funtoonorm``` can be run in a validation mode and its graphical output is used to choose optimal parameters for normalization. The function agreement accesses the performance of normalization measuring intra-replicate differences before and after normalization. It takes the output of funtoonorm as an input.
