Hello Ambuj,
I found some information about probeAnno in the packages ccTutorial,
davidTilling and Ringo.
Objects can be created by calls of the form new("probeAnno", map,
arrayName, genome).
map:
Object of class "environment" This map consists of four vectors for
each chromosome/strand, namely, say for chromosome 1:
1.start
genomic start coordinates of probe matches on chromosome 1
1.end
genomic start coordinates of probe matches on chromosome 1
1.index
identifier of probes matching at these coordinates
1.unique
vector of the same length as the three before; encoding how
many matches the corresponding probe has in the given file or
data.frame. An entry of '0' indicates that the probe matching at this
position has only this one match.
arrayName:
Object of class "character", the name or identifier of the
microarray design, e.g. 2005-06-17\_Ren\_MM5Tiling\_Set1
genome:
Object of class "character", which genome the reporters have been
mapped to
pa <- new("probeAnno")
pa["X.start"] <- seq(5000,10000,by=1000)
if (interactive()) show(pa)
I hope this help.
Regards,
Viviana
