Description Usage Arguments Details Value Examples

Computes Ratios between matrices to one control

1	metagene_ratio(m, samples, control, transform_fun = NULL, ...)

`m`	the object to create the metagene aggregate for
`samples`	sample names for one or more matrices from m to be used
`control`	sample name for one of the matrices from m to be used as denominator
`transform_fun`	a function to be applied to vlues before aggregate function is applied.
`...`	other arguments passed to fun

Ratio of values. transform_fun takes a matrix as input and returns a similar sized matrix. ie p1 <- function(m)m+1 Computes the ratio to the control matrix. Handles all groups if there is more than one group present.

a metagene object

 fname <- system.file("extdata", "matrix_grouped.gz", package = "RMetaTools")
 m <- load_deeptoolsmatrix3_new(fname)
 p1 <- function(m){return(m+1)}
 ratios <- metagene_ratio(m, c('RRP40', 'ZCCHC8', 'ZFC3H1'), 'MTR4', transform_fun=p1)
