mergeMCRProbes {cghMCR} | R Documentation |
This function takes a data frame generated by MCR
and
then append probe ids corresponding to each MCR as a column to the
data frame.
mergeMCRProbes(mcr, rawData)
mcr |
mcr is a data frame generated by MCR
that contains MCRs identified and other related data |
rawData |
rawData is a data frame with at least three
columns. The first column should be probe ids, second the chromosome
number the probes corresponding to, and the thrid the starting or
ending chromosomal locations of the probes |
The mcr
data frame passed must have the first column for
chromosome numbers, the 7th column for the starting positions of
the MCRs, and the 8th column for the ending positions of the MCRs.
A data frame with MCRs and the corresponding probe ids and other data.
The function is a contribution of The Center for Applied Cancer Science of Dana-Farber Cancer Institute
