[R] Read fst files

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.
