Focus of Release

• The major focuses of the v6.0.1 maintenance release of DataSHIELD, addressing known issues .

Changes from DataSHIELD v6.0 to v6.0.1

• Improvements to "ds.dataFrameSubset", “dataFrameSubsetDS1" and "dataFrameSubsetDS2" functions: improved argument checking and support for the "ONES" option, which will cause a vector containing "1" to be created.

• Improvements to “ds.dataFrame” and “ds.cbind” functions: ensures that the combining of variables in data frames that are created by those two functions maintains the actual class of each input variable.

• Improvements to "ds.names" and "namesDS" functions: improved checking that function is operation on a list object.

• Improvements to "ds.dataFrameFill" and "dataFrameFillDS" functions: ensures that the classes of any created columns match the classes of existing columns in the other studies.

• Enhancements of build and testing system: remove reliance on "opal" and "opaladmin" packages.
