enrichR can be installed from Github or from CRAN.
library(devtools)
install_github("wjawaid/enrichR")
The package can be downloaded from CRAN using:
install.packages("enrichR")
enrichR provides an interface to the Enrichr database (Kuleshov et al. 2016) hosted at https://maayanlab.cloud/Enrichr/.
By default human genes are selected otherwise select your organism of choice. (This functionality was contributed by Alexander Blume)
library(enrichR)
listEnrichrSites()
#> Enrichr ... Connection is Live!
#> FlyEnrichr ... Connection is available!
#> WormEnrichr ... Connection is available!
#> YeastEnrichr ... Connection is available!
#> FishEnrichr ... Connection is available!
#> OxEnrichr ... Connection is available!
setEnrichrSite("Enrichr") # Human genes
#> Connection changed to https://maayanlab.cloud/Enrichr/
#> Connection is Live!
Then find the list of all available databases from Enrichr.
<- listEnrichrDbs() dbs

View and select your favourite databases. Then query enrichr, in this case I have used genes associated with embryonic haematopoiesis.
<- c("GO_Molecular_Function_2015", "GO_Cellular_Component_2015", "GO_Biological_Process_2015")
dbs <- enrichr(c("Runx1", "Gfi1", "Gfi1b", "Spi1", "Gata1", "Kdr"), dbs)

Now view the results table.

You can give many genes.
