Small example of how to call into R code from C. This example creates an array in C, calls a function in R that adds one to each element of the array, and then prints the results from C.
To compile and run the example:
Note that you may need to adjust the path to the R header and library files in Makefile and r_test.sh to suit your system.
The R function is defined in func.R, and code to call this function from C is in r_test.c.
