Hi,
I'm new to 'R' and need some help on the "Load" command. Any responses will be highly appreciated. Thanks in advance! As per manuals, the "Load" command expects a binary file input that is saved using a "save" command. However it is required that we need to call the 'R' program from Java web application using RJava, and pass a string to the 'R" program instead of a binary file. Is it possible? I was exploring the options of using TextConnections, file connections and other types of connections in order to read a stream of input (either from a file, stdin etc). I am able to read the string, but the Save and Load commands are not accepting the string input. Here is the sequence of commands I tried running, and the error received. There is no clue on this error, especially when trying to use the eval function in randomForest package, even on the internet.
