[R] Error Reading from Connection

[Jeff Newmiller]

The "Value" section of the help page describes what the function returns... in this case a vector of 1 named integer element that is zero (success), based on the question you asked (is it readable).

Given this input I would suggest that you confirm that the software that produced this file was actually writing in RData format. Just telling it to stick an RData extension on the name you tell it to write to rarely does that. However, I have never used "Stat Transfer utility" software so I have no idea how to help with that. You might also consider using a different format for data transfer, such as CSV. While this can entail some care in specifying formats for data columns in your R script, I have found this to be the most transparent way to get data into R, since other formats don't tell you what went wrong.
