distanceCells: Minimum Distance between Two Cells

In celltrackR: Motion Trajectory Analysis

Minimum Distance between Two Cells

Description

Compute the minimum distance between two cells in the dataset (minimum over all) the timepoints where they were both measured.

Usage

distanceCells(X, cellids, quietly = FALSE)

Arguments

X	a tracks object
cellids	a vector of two indices specifying the tracks to compute distance between, or a dataframe/matrix of two columns (where every row contains a pair of cellids to compute a distance for)
quietly	if TRUE, suppress warnings about returning NA distances.

Value

A single distance (NA if the the tracks do not have overlapping timepoints), or a vector of such distances if multiple pairs are supplied in cellids.

See Also

angleCells to compute the angle between the track displacement vectors, and AngleAnalysis for other methods to compute angles and distances.

Examples

## Find the minimum distance between the tracks with ids 1 and 3
distanceCells( TCells, c("1","3") )
