intersect.samples: Intersect samples between datasets.

Description Usage Arguments Value Examples

In order to make all datasets comparable, we have to make sure they describe the same set of samples. This function takes a list of datasets (i.e. data matrices), takes the intersect of all rownames, and returns a list of datasets with only those samples.

1	intersect.samples(data)

data

A list of data matrices. The data matrices need to have rownames.

A list with of data matrices, all with the same set of samples.

set.seed(2)
n = 100
p = 100
x1 = matrix(rnorm(n*p), n, p)
x2 = matrix(rnorm(n*p), n, p)
rownames(x1) = rownames(x2) = paste0("X",1:n)
data = list(x1=x1[1:90,], x2=x2[10:100,])
data = intersect.samples(data)
