Yea that will work. It appears to be related to setting my working dir, for what
ever reason neither seem to work
(1) knitr::opts_knit$set(root.dir
="~/My_Reference_Library/Regression") # from R Notebook or
(2)
setwd("C:/Users/reichmaj/Documents/My_Reference_Library/Regression") #
from R chunk
So it appears I can either (as you suggested) use two steps or combine but I
need to enter the full path. Why other file types don't seem to need the
full path ....?????
myObject <-
read_fst(unz("C:/Users/reichmaj/Documents/My_Reference_Library/Regression/Datasest.zip",
filename = "myFile.fst"))
Thank you. I guess just one of those R things

It looks as though read_fst wants a filename, not a connection.
You should do it in two steps:
unzip("Dataset.zip", files = "myFile.fst")
myObject <- read_fst("myFile.fst")
This is obviously untested; you didn't even say what package read_fst()
comes from.
