hclust_haystack function

Function for hierarchical clustering of genes according to their expression distribution in 2D or multi-dimensional space

hclust_haystack(
  x,
  expression,
  grid.coordinates,
  hclust.method = "ward.D",
  cor.method = "spearman",
  ...
)

## S3 method for class 'matrix'
hclust_haystack(
  x,
  expression,
  grid.coordinates,
  hclust.method = "ward.D",
  cor.method = "spearman",
  ...
)

## S3 method for class 'data.frame'
hclust_haystack(
  x,
  expression,
  grid.coordinates,
  hclust.method = "ward.D",
  cor.method = "spearman",
  ...
)

Arguments

• x: a matrix or other object from which coordinates of cells can be extracted.
• expression: expression matrix.
• grid.coordinates: coordinates of the grid points.
• hclust.method: method used with hclust.
• cor.method: method used with cor.
• ...: further parameters passed down to methods.
