Dear All, I have recently started (trying) to use xmapcore for analysis of my mouse Exon 1.0 array data. Now that the install is complete, I am having trouble with the first (!) command: Connected to xmapcore_mus_musculus_58 (red0010) Selected array 'MoEx-1_0' as a default. > raw.data<-read.exon() Error: could not find function "read.exon" Since the example scripts I have managed to find are from the deprecated version, exonmap, I'm wondering if this command has changed? Sorry for such a basic question. All help gratefully received. Emma [[alternative HTML version deleted]]

Hi Emma, That error usually means that the library with the command you are trying to call is not yet loaded. If read.exon() was part of xmpacore, then you would need to just say: library("xmapcore") And demote your 1st command to being the 2nd. But since read.exon() doesn't appear to be part of xmapcore (or loaded with it), it looks like you may have other issues going on. But since you have not given us your sessionInfo() or a reproducible example, I can't fully help you out. You might want to have a look at the posting guide and try again. It really does make a big difference in terms of whether or not we can help you. http://www.bioconductor.org/help/mailing-list/posting-guide/ Marc On 10/19/2010 02:14 AM, Emma Lucas wrote: > > Dear All, > I have recently started (trying) to use xmapcore for analysis of my mouse Exon 1.0 array data.
