| cgh.image(FASeg) | R Documentation |
Given a fitted copy number matrix, this function displays the copy number as an image.
cgh.image(h.1, trunc = 4, data.scale="log2ratio")
h.1 |
The fitted copy number matrix, i.e. the output of faseg(). |
truncate |
Any copy number higher than this number will be truncated at this number. The purpose is to help adjust colors. |
data.scale |
The scale the data is on. Four possible values: "original", "ratio", "log2ratio", "log". The data is transformed to raw copy numbers to plot based on this information. Mis-specifying the scale may lead to incorrect colors. |
On the x-axis is the physical position of the chromosomes. On the y-axis are the samples.
No return value.
