1000 randomly selected probesets from a breast cancer microarray dataset (Farmer et al., 2005).
A data frame with 1000 rows and 7 variables:
Affymetrix probesets from the U133A chip.
Gene symbol.
Log2 fold change for the basal versus luminal comparison.
Mean expression across all samples.
P-value for basal versus luminal comparison.
Standard deviation across all samples.
Correlation with PCNA (a marker of proliferating cells).
These data are the results from an analysis comparing the basal and luminal samples. The apocrine samples are excluded.
