Description

A simple wrapper function for executing a remote R script.

Usage

  remoteScript(name, inputs = NULL, outputs = NULL, displayPlots = TRUE,
    writePlots = TRUE, recPlots = TRUE, async = FALSE,
    closeOnComplete = FALSE)

Arguments

`name`

The R Script file to be executed.

`inputs`

JSON encoded string of R objects that are loaded into the Remote R session's workspace prior to execution. Only R objects of type: primitives, vectors and dataframes are supported via this parameter. Alternatively the putLocalObject can be used, prior to a call to this function, to move any R object from the local workspace into the remote R session.

`outputs`

Character vector of the names of the objects to retrieve. Only primitives, vectors and dataframes can be retrieved using this function Use getRemoteObjectto get any type of R object from the remote session.

`displayPlots`

If TRUE, plots generate during execution are displayed in the local plot window. NOTE This capability requires that the 'png' package is installed on the local machine

`writePlots`

If TRUE, plots generated during execution are copied to the working directory of the local session.

`recPlots`

If TRUE, plots will be created using the 'recordPlot' function in R.

`async`

If TRUE, the remote script will be run asynchronously in a separate window.

`closeOnComplete`

If TRUE, the async R session will quit upon completion. Only applies if async=TRUE

Value

A list containing the results of the execution.

Examples


 ## Not run:

resp<-remoteExecute("myScript.R")
resp<-remoteScript("scaleRtest.R", displayPlots = FALSE, writePlots = FALSE)

#specify 2 inputs to the script and retrieve 2 outputs.  The supported types for inputs and 
#outputs are: primitives, vectors and dataframes.
data<-'[{"name":"x","value":120}, {"name":"y","value":130}]'
resp<-remoteExecute("c:/myScript.R", inputs=data, outputs=c("out1", "out2"), writePlots=TRUE)

#alternative using 4 calls
x<-120;y<-130
putLocalObject(c("x","y"))
resp<-remoteExecute("c:/myScript.R", script=TRUE)
getRemoteObject(c("out1", "out2"))
## End(Not run)
