[R] R error

[verse123]

Hi guys, 

I am new to R and I am bascially trying to load a library that I installed
and use external data that I have. When trying to use an R package called
cummeRbund (http://compbio.mit.edu/cummeRbund/), I am doing:

> library(cummeRbund)
Loading required package: RSQLite
Loading required package: DBI
Loading required package: reshape
Loading required package: plyr
> cuff <- readCufflinks(system.file("cds.diff", package="cummeRbund"))

I get this error message:

Creating database /cuffData.db
Error in sqliteNewConnection(drv, ...) :
  RS-DBI driver: (could not connect to dbname:
unable to open database file

Any ideas why?
