lnorm {LMGene} | R Documentation |
Lowess normalization function
lnorm(mat1, span = 0.1)
mat1 |
A data matrix to be normalized |
span |
Lowess smoother span. Larger values give more smoothness. |
mat1
must be a p
by n
matrix, where p
is the number of genes and n
is the number of arrays or samples
matnorm1 |
Normalized matrix |
