read_fst is from the package fst. The fileformat fst uses is a binary
format designed to be fast readable. It is a column oriented format and
compressed. So, to be able to work fst needs access to the file itself
and wont accept a file connection as functions like read.table an
variants accept.
Thanks for the info. I think it is possible to handle such a file in a
binary connection, but doing that in C/C++ would be kind of horrible, so
I can understand your choice.

Also, because it is a binary compressed format using a compression
method that is fast to read, compressing also to zip seems to defeat the
purpose of fst.

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 ....?????
You need to read the documentation for read_fst() to find what it needs.
If it doesn't explain this, then you should report the issue to its
author.
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
No, it's a read_fst() thing.
