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 Pau Marc Muñoz Torres skype: pau_marc http://www.linkedin.com/in/paumarc http://www.researchgate.net/profile/Pau_Marc_Torres3/info/ 2017-05-22 14:53 GMT+02:00 peter dalgaard <pda...@gmail.com>: > > > On 22 May 2017, at 14:43 , Pau Marc Muñoz Torres <paum...@gmail.com> > wrote: > > > > Hello everybody > > > > I am trying to use system.file but it returns not file found > > > > what I have done is > > > >> sample <- system.file("results.xlsx","estdata", package = > > "readxl",mustWork = TRUE) > > Error in system.file("results.xlsx", "estdata", package = "readxl", > > mustWork = TRUE) : > > no file found > > > > i have checked the path was correct and the file exists with > > > > FILES <- file.path("results.xlsx") > > present <- file.exists(FILES) > > > > and it returned a true values.
