• ds.skewness: calculates the skewness of a numeric variable with three different mathematical formulas 

• ds.getWGSR: computes the WHO Growth Reference z-scores of anthropometric data 

• ds.abs: computes the absolute values of an input numeric or integer variable

Changed Functions 

The following functions have been modified in this release of DataSHIELD. 

• ds.dataFrameSubset: contains additional argument checking 

• ds.glmSLMA: improved documents 

• ds.cbind: simplified, some arguments have been removed 

• ds.scatterPlot: the logical argument “return.coords” (default to FALSE) added, to allow users select if the coordinates of the anonymised data points should be returned back to the Console. If the user selects to get the coordinates on the console, he/she can then use any of the native R graphical libraries (e.g. ggplot, etc.) to generate other visualisations on the client-side 

Client-side Testing Infrastructure 

Added support for running tests which require ds.dangerClient functions as part of the Continuous Integration tests. 

Additional tests, and general test improvements are included in this release. 

Server-side Testing Infrastructure 

Added test suite to directly tests of the server functions. These tests have also been integrated with Continuous Integration. 

Generate of test coverage reports from server test suite.
