P2 Server 4.5 is the engine that powers data retrieval<\/strong> from a variety of disparate sources, with built-in relationship models<\/strong> based on a Data Dictionary. P2 Server is how you get your data, transform it into more useful data, and then serve it up to other applications such as P2 Explorer or P2 Sentinel, for further analysis.<\/p>\n Patch Release 4.5.4 introduces the new \u2018Adaptive Raw\u2019 sample method, support for .gif images, and wildcard filtering. The \u2018R Language\u2019 infrastructure is now also available as a separate licensable component.<\/p>\n This release of P2 Server introduces the R Language infrastructure, available as a separate licensable component. R is an open source programming language and software environment for statistical computing and graphics that is supported by the R Foundation for Statistical Computing<\/em>.<\/p>\n Before you can use the R Script component, ensure that Microsoft<\/strong> R Open 3.3.3<\/strong> or later<\/strong> (or the standard R installation) is installed on the same machine as P2 Server.<\/p>\n The R Language calculations allow you to access R, as a way of analysing data within your calculations.<\/p>\n RTimeSeries<\/strong>()<\/p>\n The new RTimeSeries() calculation function allows users to pass an R script into the calculation, and return values as time series data.<\/p>\n Format: RTimeSeries (Script [,Timestamp Pattern] [,Parameters])<\/span><\/p>\n Inputs<\/strong>:<\/p>\n Examples<\/strong>:<\/p>\n Expression: RTimeSeries('output$value <- parameter1', null, 5.6)<\/span> Expression: RTimeSeries('output$value <- parameter1Name', null, 2.2 + 3.4)<\/span> Expression: RTimeSeries('output$value <- smooth.spline(parameter1$timestamp, parameter1$value)$y', null, {silver})<\/span> The R adaptor is responsible for executing R scripts for the R Language functions. This adaptor supports 64-bit R engines and allows parallel R script execution by running multiple R adaptors at once with one R engine instance in each.<\/p>\n The R Adaptor differs from other adaptors in that it does not appear in P2 Server Management. Configuring the R Adaptor is done configured through the ServerConfig.xml. Here is an example configuration:<\/p>\n The parameters are described as follows:<\/p>\n Installing New Packages<\/strong><\/p>\n New packages cannot be installed using the standard installation functions, and must be installed by the system administrator. To install new packages:<\/p>\n You can now add .gif<\/strong> images in P2 Server Management. This is in addition to existing support for .png, .jpg, .ico, and .svg images.<\/p>\n

\n Script<\/strong><\/td>\n The R Input Symbols in a script that uses the R Language syntax.<\/td>\n<\/tr>\n \n Timestamp Pattern<\/strong><\/td>\n The formatting string used to pass the timestamps of the data points as text e.g. dd\/M\/yyyy H:mm:s<\/td>\n<\/tr>\n \n Parameters<\/strong><\/td>\n The parameters to use as inputs for the Script.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
\n Output: Returns 5.6 as the value for each timestamp.<\/p>\n
\n Output: Returns the string 2.2 + 3.4 as the value for each timestamp.<\/p>\n
\n Output: Fits a cubic smoothing spline on the values fetched by the Silver tag.<\/p>\nR Adaptor<\/h3>\n

\n RHome<\/strong><\/td>\n Main folder of the R installation.<\/td>\n<\/tr>\n \n RRelativePath<\/strong><\/td>\n Relative path of the R engine within the RHome folder.<\/td>\n<\/tr>\n \n RAdaptorEnabled<\/strong><\/td>\n True<\/strong> or False<\/strong>. Indicates whether the R Adaptor and thus executing R scripts is enabled. Default: false<\/td>\n<\/tr>\n \n RAdaptorMinPoolSize<\/strong><\/td>\n The smallest number of R Adaptor instances that will always be available to execute R scripts. Default: 2<\/td>\n<\/tr>\n \n RAdaptorMaxPoolSize<\/strong><\/td>\n Largest number of R scripts that the system will attempt to execute simultaneously. Default: 8<\/td>\n<\/tr>\n \n RAdaptorInitTimeout<\/strong><\/td>\n Time limit (in seconds) allowed for the R Adaptor to initially set up and configure the R engine before timing out. Default: 60<\/td>\n<\/tr>\n \n RAdaptorRequestTimeout<\/strong><\/td>\n Time limit (in seconds) applied to all non-initialization operations against the R Adaptor. Default: 600<\/td>\n<\/tr>\n \n RAdaptorDisabledFunctions<\/strong><\/td>\n Comma-separated list of additional R functions which are not allowed to be executed in R scripts. The following functions are considered insecure and are already permanently disabled in the R Adaptor: detach(), eval(), file.remove(), install.packages(), library(), require(), shell(), source(), system(), system2(), and unlink().<\/td>\n<\/tr>\n \n RAdaptorEnabledPackages<\/strong><\/td>\n Comma-separated list of R packages which will be pre-loaded by the R Adaptor for executing R scripts. If a package is not in this list then it cannot be used inside a R expression. See Installing New Packages<\/em> below.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n \n
