Subject: Re: [R] read.csv and Decimal places

... and see also ?print.data.frame , the "digits" argument.
See also ?str

It might be worth your while spending time with an R tutorial or two that covers such topics, i.e. distinguishing between an object and various (S3) methods that "represent" it, such as print(), summary(), plot()  etc.

The stored numbers are correct.  They are rounded on printing.
print(RevFCast, digits=17)

See
?options
And scroll down to digits.
