Description Usage Arguments Value Author(s) Examples

Function for primary code to perform co-expression analysis, with or without data transformation,
using mixture models. The output of `coseq_run`

is an S3 object of class `coseq`

.

`y` |
( |

`K` |
Number of clusters (a single value or a vector of values) |

`conds` |
Vector of length |

`norm` |
The type of estimator to be used to normalize for differences in
library size: (“ |

`model` |
Type of mixture model to use (“ |

`transformation` |
Transformation type to be used: “ |

`subset` |
Optional vector providing the indices of a subset of
genes that should be used for the co-expression analysis (i.e., row indices
of the data matrix |

`meanFilterCutoff` |
Value used to filter low mean normalized counts if desired (by default, set to a value of 50) |

## Simulate toy data, n = 300 observations
set.seed(12345)
countmat <- matrix(runif(300*4, min=0, max=500), nrow=300, ncol=4)
countmat <- countmat[which(rowSums(countmat) > 0),]
conds <- rep(c("A","B","C","D"), each=2)
## Run the Normal mixture model for K = 2,3,4
## The following are equivalent:
run <- coseq_run(y=countmat, K=2:4, iter=5, transformation="arcsin")
run <- coseq(y=countmat, K=2:4, iter=5, transformation="arcsin")
