Description

row_norm_to_median normalizes all the frame-rows by the median of a number of them..

Usage

row_norm_to_median(dd, normCols, rowInds = NULL, colInds = NULL)

Arguments

dd	input data frame to normalize
normCols	A vector of indices that pick columns. Medians are calculated from these in row-wise manner, and they are used to normalize each row. May be a function like 'span'
rowInds	A span of row indices over which to operate. These should be the data rows, and this is just so that you can have other ignored rows be in there. This can be NULL, in which case all rows are normalized, or it can be a vector of integer indices, or it can be a function that gets called with dd and which returns a vector of ints (see function 'span' in this package)
colInds	A span of column indices over which to operate. These should be the data columns, and this is just so that you can have other ignored columns be in there. This can be NULL, in which case all columns are normalized, or it can be a vector of integer indices, or it can be a function that gets called with dd and which returns a vector of ints (see function 'span' in this package)

Value

returns the input data frame, but with the data cols normalized.
