Description

Base function for executing a block of R code or an R script in the remote R session

Usage

  remoteExecute(rcode, script = FALSE, inputs = NULL, outputs = NULL,
    displayPlots = FALSE, writePlots = FALSE, recPlots = FALSE)

Arguments

rcode

The R code, or an R Script file to be executed

script

If TRUE, treat the rcode parameter as a R script file name

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

The console output will be refreshed at a recurring rate. the default is 5000 milliseconds (5 seconds). By setting the option 'mrsdeploy.console_update', you can override this value (i.e. options(mrsdeploy.console_update=7000) Use caution when changing this value to something less than 5000 ms, as it may place a necessary load on the deployr server.
Values less than 1000 will disable refreshing of the console.

Value

A list containing the results of the execution

Examples


 ## Not run:

#execute a block of R code
resp<-remoteExecute("x<-rnorm(10);y<-rnorm(10);plot(x,y)", writePlots=TRUE)

#execute an R script
resp<-remoteExecute("c:/myScript.R", script=TRUE)

#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", script=TRUE, 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"))
