RExpression actor problem with large string arrays
Currently the RExpression actor handles very large arrays of input by means of an intermediate file that is read using the R 'scan' function. (Strings are used as input for smaller arrays, but the input system of R can only handle a limited size). Kevin Drury reported a problem, however, with a large string array.
The problem is the the 'scan' function defaults to numeric values. The RExpression actor code needs to be fixed to handle large string arrays that a placed in an intermediate file. (It seems to work OK for large numeric strings, and for small string arrays not written to a file.)
