simgroups: Simulate group data through R package Splatter
In xzheng-ac/scPADGRN: A PADMM approach for reconstructing DGRN using scRNA-seq

Description Usage Arguments Value Examples

This function simulate group data through R package Splatter

1	simgroups(m, n, k)

`m`	m is the gene number
`n`	n is the cell number
`k`	k is the group/cluster number

Returned value 'sim.group' is an S4 structure, and it contains single cell data with group/cluster information of each cell.

##---- Should be DIRECTLY executable !! ----
##-- ==>  Define data, use random,
##--	or do  help(data=index)  for the standard data sets.

## The function is currently defined as
function (m, n, k)
{
    params <- newSplatParams()
    params <- setParams(params, nGenes = m)
    params <- setParams(params, batchCells = n)
    rk <- 1/k
    params <- setParams(params, group.prob = c(rep(rk, k - 1),
        1 - (k - 1) * rk))
    sim.groups <- splatSimulate(params, method = "group", verbose = FALSE)
    sim.groups <- normalize(sim.groups)
    return(sim.groups)
  }
