i met some problems when installing the packages"cummeRbund",

library(cummeRbund) and it went like

The following object is masked from 'package:GenomicRanges':

    promoters

The following object is masked from 'package:IRanges':

    promoters

The following object is masked from 'package:BiocGenerics':

    conditions

i wanted to check the cummeRbund whether it run correctly, so i typed

cuff <- readCufflinks(dir=system.file("extdata", package="cummeRbund"))

it went like
