Hi Folks, If you need to send data from Java to R you may consider using the JDataFrame API -- which is used to convert data into JSON which then can be converted into a data frame in R.
Here's the project page: https://coherentlogic.com/middleware-development/jdataframe/ and here's a partial example which demonstrates what the API looks like: String result = new JDataFrameBuilder() .addColumn("Code", new Object[] {"WV", "VA", }) .addColumn("Description", new Object[] {"West Virginia", "Virginia"}) .toJson(); and in R script we would need to do this: temp <- RJSONIO::fromJSON(json) tempDF <- as.data.frame(temp) which yields a data frame that looks like this: > tempDF Description Code 1 West Virginia WV 2 Virginia VA It is my intention to deploy this project to Maven Central this week, time permitting. Questions and comments are welcomed. Tom ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
