I hadn't seen the distinction between the commandline in RGui and what
happens within my code.
I have, however seen other differences I don't understand. For
example, looking at the documentation for RScript, I see:

You have to explicitly 'print' the value of x in the loop:print(x)
'x' by itself is just it value. At the command line, typing an
objects name is equivalent to printing that object, but it only
happens at the command line. If you want a value printed, the 'print'
it. Also works at the comma

So it does. My bad.

Yes. I had forgotten that not everyone sets options

Actually, I'd tried single brackets first. Here is what I got:

No. This won't help. V4 is a column of the data frame optdata,
and hence is a vector. Not a list! Use single brackets --- V4[i] ---
and all will be well
try putting as.character in the call:
x = read.csv(as.character(V4[[i]]), header = FALSE

Here is what I tried:
optdata =
read.csv("K:\\MerchantData\\RiskModel\\AutomatedRiskModel\\soptions.dat",
header = FALSE, na.strings="")
optdata
attach(optdata)
for (i in 1:length(V4) ) { x = read.csv(V4[[i]], header = FALSE,
na.strings="");x }
And here is the outcome (just a few of the 60 reco
