In wmm27/idpr: Profiling and Analyzing Intrinsically Disordered Proteins in R

idpr

Overall, ‘idpr’ aims to integrate tools for the computational analysis of intrinsically disordered proteins within R. This package is used to identify known characteristics of IDPs within a sequence of interest with easily reported and dynamic results. Additionally, this package also includes tools for IDP-based sequence analysis to be used in conjunction with other R packages. See our recently published peer-reviewed publication in PLOS ONE (https://doi.org/10.1371/journal.pone.0266929)

Please Refer to idpr-vignette.Rmd file for a detailed introduction to the idpr package.

Installation

You can install the stable release version version from Bioconductor with:

if (!requireNamespace("BiocManager", quietly = TRUE))
    install.packages("BiocManager")

BiocManager::install("idpr")

Additionally, you can install the development version from Bioconductor with:

if (!requireNamespace("BiocManager", quietly = TRUE))
    install.packages("BiocManager")

# The following initializes usage of Bioc devel
BiocManager::install(version='devel')

Or you can install the most recent development version from GitHub with:

# install.packages("devtools") #if not already installed
devtools::install_github("wmm27/idpr")

Example

This is a basic example to quickly profile your protein of interest:

library(idpr)

P53_HUMAN <- TP53Sequences[2] #Getting a pre-loaded sequence from idpr
print(P53_HUMAN)
#>                                                                                                                                                                                                                                                                                                                                                                                            P04637|P53_HUMAN
