addQuantilesColors {a4Base} | R Documentation |
Compute quantiles on mean expression level for plotGeneDE function. Colors of bars in the plot could then be allocated using buckets defined by those quantiles.
addQuantilesColors(e, ngroups = 3)
e |
ExpressionSet object to use for computation |
ngroups |
Number of groups to be created |
Number of computed quantiles is equal to (ngroups - 1).
The ExpressionSet object e is returned, with a new column called colorsQuantilesVector in its slot featureData
