u133VsExon {GMCM}

Reproducibility between U133 plus 2 and Exon microarrays

Description

This dataset contains a data.frame of unadjusted P-values for differential expression between germinal center cells and other B-cells within tonsils for two different experiments. The experiments differ primarily in the microarray platform used. The first column corresponds the evidence from the Affymetrix GeneChip Human Genome U133 Plus 2.0 Array. The second column corresponds to the Affymetrix GeneChip Human Exon 1.0 ST Array.

Format

The format of the data.frame is:

'data.frame': 19577 obs. of 2 variables:
$ u133: num 0.17561 0.00178 0.005371 0.000669 0.655261 ...
$ exon: num 1.07e-01 6.74e-10 1.51e-03 6.76e-05 3.36e-01 ...
