I found quality report for affymetrix data using package AffyExpress quite complete and interesting. However, I was disappointed by the impossibility of choosing a relative folder where I could store the html ouput. Besides, if possible, it would be great to combine all png outputs into a single HTML document, if possible, instead of keeping them separated.

# include your problematic code here with any corresponding output 

AffyExpress::AffyQA(parameters = c("disease status:ch1"), raw= affybatch_microarray,Output = "GSE23117_QAReports.html") # working

 AffyExpress::AffyQA(parameters = c("disease status:ch1"), raw= affybatch_microarray,Output = "Control_Quality/GSE23117_QAReports.html") # not working, as not finding relative path of Control_Quality

AffyExpress::AffyQA(parameters = c("disease status:ch1"), raw= affybatch_microarray, Output= "/home/bncl_cb/rstudio/working/bmkanalysis/tests/testthat/Control_Quality/GSE23117_QAReports.html") # not working as well with absolute path

Error in file(file, ifelse(append, "a", "w")) : 
  cannot open the connection
In addition: Warning message:

Here's my sessionInfo: it would be great to both specify a filename in relative and absolute path, as being platform-independant using functions normalizePath and path.expand on R.
