• Configuration file: heatmap_config.xml

• Image files:

  • static/images/heatmap_workflowPositionImage.png
  • static/images/heatmap_workingExampleImage.png

• Wrapper file: heatmap_wrapper.R

• R packages

  • batch from CRAN

INTERNAL MODIFICATION

• Minor internal modifications

NEW FEATURES

• Default method for the correlation coefficient is now 'pearson', instead of 'spearman' previously (the latter can still be selected in the advanced parameters)

• The 1-abs(correlation) dissimilarity is now available (in addition to the default '1-correlation') in case the sign of correlations between samples and between variables does not matter, as well as the euclidean, maximum, manhattan, canberra, binary, and minkowski dissimilarities

• A new red-green color scale is available

INTERNAL MODIFICATION

• Creating additional files for planemo and travis validation

INTERNAL MODIFICATION

• Creating tests for R code
