Nothing to worry about. Everything should work as expected. Those are *warnings* not *errors*. In R, there is a strict difference between the two. Typically when you get an *error*, the R function/script stops, whereas with a *warning* everything continues. Compare: > log("a") Error in log("a") : Non-numeric argument to mathematical function and > log(-1) [1] NaN Warning message: In log(-1) : NaNs produced > > I'm trying to analyze huex chips.

Have a look at the directory ./reports/Control/<some tags>/ and you should see a file ArrayExplorer.html. Look in its subdirectories and you should see large PNG files containing the spatial plots. Open that in Firefox(!). Alternatively, you could also try display(ae) if your default browser is Firefox. /Henrik > > Any suggestions would be greatly appreciated!! > Thanks > > -K > > -- > When reporting problems on aroma.affymetrix, make sure 1) to run the latest > version of the package, 2) to report the output of sessionInfo() and > traceback(), and 3) to post a complete code example. > > > You received this message because you are subscribed to the Google Groups > "aroma.affymetrix" group with website http://www.aroma-project.org/. > To post to this group, send email to aroma-affymetrix@googlegroups.com > To unsubscribe and other options, go to http://www.aroma-project.org/forum/ > -- When reporting problems on aroma.affymetrix, make sure 1) to run the latest version of the package, 2) to report the output of sessionInfo() and traceback(), and 3) to post a complete code example.
