title: Install R package "sqldf" (RSQLite.extfuns) locally
body: <p>I'm trying to install the R-package <code>sqldf</code> on a Linux-pc where I don't have root access.
  When R tries to install the package <code>RSQLite.extfuns</code> it fails because the library <code>sqlite3ext.h</code> is missing. As i can't install the library globally i downloaded and compiled it in my home directory. But how can i tell <code>R</code> (or gcc) now where the library is located. It searches at <code>/usr/local/include</code> and <code>/usr/lib64/R/library/...</code> but I don't have access to those locations.</p>
  
  <p>Thanks in advance!</p>
