External Communication

Dinamica EGO can communicate with external applications by exposing a communication session. By default, an opened session will be created and its name is displayed on the status bar:

To send and receive data, the functors under the 'External Communication' folder in the Library can be used.

The following packages are necessary for sending and receiving data using R. To install the packages, do:

install.packages(c("Rcpp", "RcppProgress", "rbenchmark", "inline"))

Then, install R Tools from https://cran.r-project.org/bin/windows/Rtools/

Download Dinamica Package for R and install it (using RStudio):

Tools -> Install Packages...

The Dinamica R package contains all the documentation available on this page, including examples and R Studio references.

To connect to an existing session:

Dinamica::openSession("DinamicaEGO") # "DinamicaEGO" is the session name.

To send a number (e.g. 3.14):

Dinamica::sendNumber(3.14);

To receive a number:

myNumber <- Dinamica::receiveNumber(); # Will receive a number in myNumber variable

To send a list of numbers (e.g. [1,10]):

Dinamica::sendNumberVector(c(1,10)); # Sends 1,2,3,4,5,6,7,8,9,10

To receive a list of numbers:

myList <- Dinamica::receiveNumberVector(); # Will receive a list of numbers in myList variable.

To send a lookup table (e.g. 1 → 2; 2 → 3; 3 → 4):

lookupTable <- list(keys = c(1,3), values = c(2,4));
Dinamica::sendLookupTable(lookupTable$keys, lookupTable$values); # Send 1 -> 2; 2-> 3; 3->4

To receive a lookup table:

myLUT <- Dinamica::receiveLookupTable(); # Will receive a lookup table in myLUT variable.

To send a string (e.g. “testing!”):

Dinamica::sendString("testing!"); # Send "testing!"

To receive a string:

myString <- Dinamica::receiveString(); # Will receive a string in myString variable.
