[R] Read fst files

Eric

 

Typo on my point. 

 

setwd("C:/Users/reichmaj/Documents/My_Reference_Library /Regression")

myObject <- read_fst(unz("Dataset.zip", filename =
"myFile.fst")) # read fst file

 

Error in path.expand(path) : invalid 'path' argument

 

So then I tried

 

myObject <-
read_fst(unz("C:/Users/reichmaj/Documents/My_Reference_Library /Regression
/Dataset.zip", filename = "myFile.fst"))

 

Error in path.expand(path) : invalid 'path' argument

 

Error in the path??

 

Because this works just fine

 

myObject <-
read.csv(unz("C:/Users/reichmaj/Documents/My_Reference_Library /Regression
/Dataset.zip", filename = "myFile.csv"))

 

My only though is I can?t use the two function s together when dealing with fst
files ??

You are missing the second closing parenthesis. This is what the error message
is telling you.

Anyone know why the following line of code would error out:  myObject <-
read_fst(unz("Dataset.zip", filename = "filename.fst"))



Error: Incomplete expression: filename <-
read_fst(unz("Dataset.zip",
filename = "filename.fst") 



I often use similar code with *.csv files in a zipped folder. For example:
myObject <- read.csv(unz("Dataset.zip", filename =
"filename.csv")), which
works just fine.

[R] Read fst files

Even if ultimately you want to use the functions together, for debugging
the problem you should split them into two, as in

a <- unz("C:/Users/reichmaj/Documents/My_Reference_Library /Regression
/Dataset.zip", filename = "myFile.fst")
See if that works, and examine 'a'.

And once that is working

read_fst(a)

to see what that does.

Let us know.

[R] Read fst files

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.
