slingshot_conditions: Refitting slingshot per condition

In HectorRDB/condiments: Differential Topology, Progression and Differentiation.

Refitting slingshot per condition

Description

Based on an original slingshot object, refit one trajectory per condition, using the same skeleton.

Usage

slingshot_conditions(sds, ...)

## S4 method for signature 'SlingshotDataSet'
slingshot_conditions(
  sds,
  conditions,
  approx_points = 100,
  adjust_skeleton = TRUE,
  verbose = TRUE,
  ...
)

## S4 method for signature 'SingleCellExperiment'
slingshot_conditions(
  sds,
  conditions,
  approx_points = 100,
  adjust_skeleton = TRUE,
  verbose = TRUE,
  ...
)

## S4 method for signature 'PseudotimeOrdering'
slingshot_conditions(
  sds,
  conditions,
  approx_points = 100,
  adjust_skeleton = TRUE,
  verbose = TRUE,
  ...
)

Arguments

sds	A slingshot object already run on the full dataset. Can be either a SlingshotDataSet or a SingleCellExperiment object.
...	Other arguments passed to getCurves
conditions	Either the vector of conditions, or a character indicating which column of the metadata contains this vector.
approx_points	Passed to getCurves
adjust_skeleton	Boolean, default to 'TRUE'. Whether to recompute the locations of the nodes after fitting per conditions.
verbose	Boolean, default to 'TRUE'. Control whether messages are printed.

Value

A list of SlingshotDataSet, one per condition.

Examples

data('slingshotExample', package = "slingshot")
rd <- slingshotExample$rd
cl <- slingshotExample$cl
condition <- factor(rep(c('A','B'), length.out = nrow(rd)))
condition[110:139] <- 'A'
sds <- slingshot::slingshot(rd, cl)
sdss <- slingshot_conditions(sds, condition)
