CALIB (version 1.38.0)

dimnames: Retrieve the Dimension Names of an RGList\_CALIB or SpikeList object.

Description

Retrieve the the dimension names of an RGList\_CALIB object or an SpikeList object

Usage

"dimnames"(x)

Arguments

x

an object of class RGList_CALIB or SpikeList.

Value

Either NULL or a list of length 2. If the value is a list, its componets are either NULL or a character vector with the length of the appropriate dimension of x. If the list component is not NULL, the first field of the list indicates rownames and the second field indicates colnames.

Details

The dimension names of a micrroarry object or a spike object are the same as those of the most important matrix component of that object.

A consequence is that row and column command rownames and colnames also work.

Examples

# for RGList_CALIB
R <- G <- matrix(1:8,4,2)
rownames(R) <- rownames(G) <- c("g1","g2","g3","g4")
colnames(R) <- colnames(G) <- c("a1","a2")
RG <- new("RGList_CALIB",list(R=R,G=G))

dimnames(RG)

# for SpikeList
SR <- SG <- matrix(1:8,4,2)
rownames(SR) <- rownames(SG) <- c("s1","s2","s3","s4")
colnames(SR) <- colnames(SG) <- c("a1","a2")
spike <- new("SpikeList",list(R=SR,G=SG))
