Hi, I'm pretty new to R and bioconductor but am happily using loads of time getting things to work... One thing I've stumpled upon trying to get geneplotter to work... The vignette happily says library("hu6800") which doesn't work for me - I had to manually download and install the hu6800 annotation package. Later I realised that a library("annotate") installDataPackage() would have done the trick - for many "first time users" - the various chip descriptions and annotations hasn't been downloaded automatically (yet). And yes - I know that this actually applies to the "annotate" package - but my problem was when trying to use geneplotter and the correspoding vignette. Also - I'm searching like crazy for help on creating my own ChromLocation object from my own data - if anybody know of this kind of help it would be greatly appreciated. (Or just some more doc. on the class itself - making it a littler simpler for me to "assemble an object of class chromLocation"...
