cs_fold-methods | R Documentation |

The inverse operation to `cs_unfold`

.

cs_fold(mat, m = NULL, modes = NULL) ## S4 method for signature 'DelayedArray' cs_fold(mat, m, modes)

`mat` |
DelayedArray object (only 2D) |

`m` |
the mode corresponding to cs_unfold |

`modes` |
the original modes of the DelayedArray |

This function is an extension of the `cs_fold`

by DelayedArray.

This is a wrapper function to `fold`

.
