Hi everyone, 

i installed mygene package and i'd try to use it to convert gene-symbols to gene-EntrezID but it returns me this error: 

> xli <- c('Glb1_mapped', 'Gm1012', 'Gnptag' )
> queryMany(xli, scopes="symbol", fields="entrezgene", species="rat")
Error in queryMany(xli, scopes = "symbol", fields = "entrezgene", species = "rat") : 
  impossible de trouver la fonction "queryMany"

Can you tell me please what's wrong?

Thank you in advance

Amal

Any time you see the error

Impossible de trouver la fonction 'queryMany'

it means that you haven't loaded the package that contains that function yet. So if you have installed mygene, you still need to do

library(mygene)

in order to use any of the functions in that package.

Thank you so much for replying James! 

i've loaded the package, but i still have an error: 

> xli <- c('Glb1_mapped', 'Gm1012', 'Gnptag' )
> queryMany(xli, scopes="symbol", fields="entrezgene", species="rat")
Finished
Error in rename(df, c(X_id = "_id")) : 
  Some 'from' names in value not found on 'x': X_id

Does it mean that the symbols are simply not found? 

Thanks
