This is a data frame consists 5 variables.
data(HU)
A data frame with 75714 observations on 5 variables:
[,1] | HUid | gene identification number |
[,2] | HUslide | slide number |
[,3] | HUblock | block number within each slide |
[,4] | HUint | total intensity 0.5log_2(RG) |
[,5] | HUratio | intensity ratios log_2frac{R}{G} |
where R is background adjusted signal intensity in the Cy5 channel, G is background adjusted signal intensity in the Cy3 channel.
These data is the part of data set generated by human placenta versus the universal reference hybridization by Dr. Bento M. Soares lab in the University of Iowa. The data sets were used by Wang et al. (2006,2007) for the purpose of methodology demonstration.
