matTesting {switchBox} | R Documentation |
A numerical matrix containing gene expression matrix
for 70 genes and 307 breast cancer patients (test set data)
from the Buyse et al cohort
(see the mammaPrintData
package).
data(testingData)
The matTesting
matrix contains normalized
expression values for the 70 gene signature (rows)
across 307 samples (columns).
Group information (emph“bad” versus “good” prognosis)
is shown in colnames(matTesting)
.
This dataset corresponds to the breast cancer patients' cohort
published by Buyse and colleagues in JNCI (2006).
The gene expression matrix was obtained from
the mammaPrintData
package as described
by Marchionni and colleagues in BMC Genomics (2013).
