hgu95Achrom {annotate} | R Documentation |
Data, in the form of environments for the Affymetrix U95A chip.
data(hgu95Achrom) data(hgu95AchromNames)
This data set provides an environment (treat as a hashtable)
with mappings from the Affymetrix
identifiers to chromosome number/name.
The environment functions like a hashtable and can be accessed using
multiget
.
If the returned value is NA
then the current
mapping was unable to identify this. Mappings and data sources are
constantly evolving so updating often is recommended.
hgu95AchromNames
is a character vector with the chromosome
names in the order, 1 through 22 then X then Y. This is useful
for ordering the chromosomes in some plotting functions.
The AnnBuilder
package.
