Error: package ‘org.At.tair.db’ could not be loaded

Kindly help me for above error.

You are using an old version of Bioconductor with a new version of RSQLite, see, e.g., error with many packages: "Error : .onLoad failed in loadNamespace() for 'org.Hs.eg.db'". The best solution is to install a current version of R, being sure to update your packages. For further help, please edit your question to include the output of the command sessionInfo().
