matrixCenter: Centering a numeric matrix
In wayneliuq/wmisc: Wayne's Misc Helper Function
Description
Plotting heatmaps of gene expression data in numeric matrices often is the most clear when
each gene is centered on 0. Since most expression data is log2 transformed, scaling of data
is not desirable.
Usage
1
matrixCenter(lx, MARGIN = 1, scale = F)
Arguments
lx
a numeric matrix
MARGIN
a vector giving the subscripts which the function will be applied over. E.g.,
for a matrix 1 indicates rows, 2 indicates columns, c(1, 2) indicates rows and columns.
scale
either a logical value or a numeric-alike vector of length equal to the number
of columns of x.
