Alas, it wasn't this. Here is the output from both of your suggestions:
> refdata18 = read.csv("K:\\MerchantData\\RiskModel\\Capture.Week.18.csv",
> header = TRUE,na.strings="")
> str(refdata18)
'data.frame': 341 obs. of 1 variable:
$ X0: int 0 0 0 0 0 0 0 0 0 0 ...
> scan("K:\\MerchantData\\RiskModel\\Capture.Week.18.csv", what=0L)
