The PEIMAN2 package @PEIMAN2 provides functions and mined database from UniProt for single enrichment analysis (SEA) and protein set enrichment analysis (PSEA) in a list of protein. The database is updated regularly with monthly changes in UniProt/SwissProt repository. To ensure you have the latest version of database, make sure to install the package from GitHub.
You can install the released version of PEIMAN from CRAN with:
install.packages("PEIMAN2")And the development version from GitHub with:
# install.packages("devtools")
devtools::install_github("jafarilab/PEIMAN2")
# or
devtools::install_github("pnickchi/PEIMAN2")# Load PEIMAN2 package
library(PEIMAN2)
# First example dataset
pl1 <- exmplData1$pl1
# Run SEA on the list
enrich1 <- runEnrichment(protein = pl1, os.name = 'Homo sapiens (Human)')
