| avedups {limma} | R Documentation |
Condense a microarray data object so that values for within-array replicate spots are replaced with their average.
## Default S3 method: avedups(x, ndups=2, spacing=1, weights=NULL) ## S3 method for class 'MAList' avedups(x, ndups=x$printer$ndups, spacing=x$printer$spacing, weights=x$weights) ## S3 method for class 'EList' avedups(x, ndups=x$printer$ndups, spacing=x$printer$spacing, weights=x$weights)
x |
a matrix-like object, usually a matrix, |
ndups |
number of within-array replicates for each probe. |
spacing |
number of spots to step from a probe to its duplicate. |
weights |
numeric matrix of spot weights. |
A new data object is computed in which each probe is represented by the (weighted) average of its duplicate spots.
For an MAList object, the components M and A are both averaged in this way.
For an EList object, the component E is averaged in this way.
If x is of mode "character", then the duplicate values are assumed to be equal and the first is taken as the average.
A data object of the same class as x with 1/ndups as many rows.
