[R] Problem in executing R-script

[Sarah Goslee]

Hi Suhaila,

You don't need to make a function: your script should just contain:
med <- read.csv("medicalData.csv")

If you do want to make a function, then you need to assign the
resulting value to something, eg:

med <- readData()

but there's no reason to do that. Values that are assigned within a
function don't persist in the global environment.
