transfo |
a function to transform the data before plotting. See 'Details'. |

number of units to sample and build the plot. |

The 'transfo' argument will set the transformation to be used. For raw data, 'transfo=log2' is a common practice. For summarized data (which are often in log2-scale), no transformation is needed (therefore 'transfo=identity').
The hist methods for FeatureSet
and Expression
use a
sample (via sample
) of the probes/probesets to produce the
plot (unless nsample > nrow(x)). Therefore, the user interested in reproducibility is advised to
use set.seed
.
