In GEO analysis, there are many different GPL platform as I should get the corresponding information of package before loading the .db R library, so I downloaded sort of GPL .db R library as the following:

GPL17897  Homo sapiens       hthgu133a

Herein, I want to just input the GPL number, then the corresponding library can be loaded


However, there is an error report typed that the package cannot be loaded in this way due to the length of the package is not 1, so how should I do to install a package by a variable?

Assuming that you have used install.packages(), any particular reason for not loading it using library() at the beginning of your function?

Use the character.only argument from the library() function :
