hi to you both

 You are right peter, I probably miss understood the system.file function.
I was trying to use it with a package from bioconductor and when i saw that
it didn't work for me, I tested with readxl and still do not working, so I
am doing something wrong with system.file

the original script was


library(SICtools)

bam1 <- system.file(package='SICtools','extdata','example1.bam')

the example1.bam file is supposed to be at the working directory (i changed
the directory using setwd()), it was changed to /home/paumarc/Bam

 i tried to change extdata for my working directory but it did not work

thanks
