  • Removed useRef parameter from getSumExpFromGenotypeTable() function.
    • This is now automatically detected from the file input.
    • This fixes ref/alt allele vs major/minor allele encoding issues.
  • Added Journal of Open Source Software citation for the rTASSEL package.
    • For citation information, use utils::citation("rTASSEL")
  • Added data object, rtPaths
    • Includes paths to external toy data for rTASSEL

rTASSEL 0.9.27

  • No significant updates in this version. This version is virtually identical to 0.9.26 and is for linking to Zenodo for archival purposes.

rTASSEL 0.9.26

  • Bug fixes:
    • Fixed r2 parameter bug in ldPlot()
    • Fixed space bugs in certain column names of data frame objects. _ values now replace spaces.
    • Fixed show() method for TasselDistanceMatrix objects.
  • Add new function:
    • seqDiversity()
    • Calculates diversity basic diversity metrics on genetic data.

rTASSEL 0.9.25

  • Bug fixes:
    • Fixed character conversion bug in DataFrame object returns.
  • pca() can optionally report eigenvalues and eigenvectors as a list object.
  • Added new function:
  • Added new function:
    • imputLDKNNi()
    • Allows for LD KNNi imputation of GenotypeTable objects.

rTASSEL 0.9.24

    • pca()
    • Allows for user to run PCA on rTASSEL objects containing a GenotypeTable object.
  • Added new function:
    • mds()

  • Enhancements:
    • New summary print output for TasselDistanceMatrix objects.

rTASSEL 0.9.23

  • Added new TasselDistanceMatrix class
    • Specified function (kinshipMatrix() and distanceMatrix()) now return an object of type TasselDistanceMatrix.
    • Prevents console overload and freezing as seen with large distance matrix objects.
    • Now shows summary overview of matrix instead of Java object reference.
    • Generic functions colnames(), rownames(), ncol(), and nrow() will return relative information similar to how these operate with matrix type objects.
    • Primitive function as.matrix() now supersedes deprecated functions kinshipToRMatrix() and distanceToRMatrix().
    • Prior functions that take in a kinship object will now take in this new class.
  • Added new function:
  • Added new function:
    • asTasselDistanceMatrix()
    • Coerces a pairwise matrix (e.g. m x m dimensions) with the same column and row names of type matrix to an object of type TasselDistanceMatrix.
  • Added new function:
    • createTree()
    • interface to TASSEL’s tree creation methods
    • Allows for Neighbor_Joining and UPGMA methods
  • Added new function:
    • treeJavaApp()
    • wrapper for TASSEL’s interface to the Archaeopteryx Java tree Viewer
    • Implements same methods for tree creation as createTree()

rTASSEL 0.9.22
