getSYMBOL {EMBO03} | R Documentation |
The functions documented here are intended to make it easier to map from a set of manufacturers identifiers (such as you will get from the chips etc) to other identifiers.
getSYMBOL(x, data = "hgu95a") getLL(x, data = "hgu95a") getGO(x, data = "hgu95a") getPMID(x, data = "hgu95a") getGOdesc(x, which=c("MF","BP","CC") )
x |
The identifiers to be mapped (usually manufacturer) |
data |
A character string identifying the data source |
which |
For getGOdesc indicates which GO hierarchy to use. |
Appropriate translations are done. In some cases such as getLL
and getSYMBOL
there will only be one match and a vector is
returned. In other cases such as getPMID
and getGO
there
may be multiple matches and a list is returned.
For getGOdesc
the input vector is GO identifiers (not
manufacturer identifiers) and in the output any identifier that does
not have a description in the selected GO hierarchy (MF, BP or CC) is
dropped.
Either a vector or a list depending on whether multiple values per input are possible.
