Data Exchange Between R and 'LabKey' Server

The 'LabKey' client library for R makes it easy for R users to load live data from a 'LabKey' Server, < http://www.labkey.com/>, into the R environment for analysis, provided users have permissions to read the data. It also enables R users to insert, update, and delete records stored on a 'LabKey' Server, provided they have appropriate permissions to do so.

See the Rlabkey Users Guide for an overview of the package.

Changes in Version 0.0.9 o Misc bug fixes

Changes in Version 0.0.8 o The following filter names have been added in the makeFilter function: QC_VALUE NOT_QC_VALUE

Changes in Version 0.0.7 o In previous versions this package would only bring labkey data into R that had hidden columns (ie, keys or other identifiers not usually shown to the user). Now any labkey data, with or without hidden columns, can be brought into R.

Changes in Version 0.0.6 o Replaced the stripAllHidden argument with showHidden. This affects the labkey.selectRows and labkey.executeSql functions and was done for clarity. The old default stripAllHidden=TRUE is replaced by the new default showHidden=FALSE which has the same functionality. See documentation for details. o The old stripAllHidden flag was removed from labkey.insertRows, labkey.updateRows and labkey.deleteRows. It served no use in these functions. The stripAllHidden (now replaced by showHidden) is only meaningfull when data are being returned to the user. o The following filter names have been modified in the makeFilter function: EQUALS -> EQUAL NOT_EQUALS -> NOT_EQUAL NOT_EQUAL_OR_NULL -> NOT_EQUAL_OR_MISSING IS_MISSING -> MISSING IS_NOT_MISSING -> NOT_MISSING GREATER_THAN_OR_EQUAL_TO -> GREATER_THAN_OR_EQUAL LESS_THAN_OR_EQUAL_TO -> LESS_THAN_OR_EQUAL

The filter name changes were made for clarity and consistency with the other software packages that retrieve data from a Labkey database.

Changes in Version 0.0.5 o modified the makeDF function to speed up data frame creation from the meta data o labkey.deleteRows function now accepts an entire row of data as input instead of just the Key column

Changes in Version 0.0.4 o first CRAN release of the Rlabkey package
