How do I load an rds file into R

I'm trying load a rds file which should contain some data.

Professor says to use readRDS(), however R gives this long error message which I've not been able to decipher myself.

I'm trying to load the file and place it in an Object.

I hope that someone are able to provide some clever solution to this problem.

Canteen_clean <- readRDS("C:/Users/a_s_j/OneDrive/Studie/Cand.merc.Business Intelligence/1. Semester/R for Business Analytics/.Rproj/39 - Graphics/Exercises02/canteen_clean.rds")

Error in gzfile(file, "rb") : cannot open the connection
In addition: Warning message: In gzfile(file, "rb") : cannot open compressed file 'C:/Users/a_s_j/OneDrive/Studie/Cand.merc.Business Intelligence/1. Semester/R for Business Analytics/.Rproj/39 - Graphics/Exercises02/canteen_clean.rds', probable reason 'No such file or directory'

I'm using: pacman::p_load("pacman", "tidyverse") to load the packages that should be necessary.

You can try using setwd()

reach to that folder location then use

list.files()

to list all the files present in that folder

then use

t1 <- readRDS("/filename.rds")
head(t1)

to get that data.

Hope it solves your issue.

Rather than typing a long file path, a really good idea in R is to let the system do the typing for you. That is, do something like this:

 filename <- file.choose()
 Canteen_clean <- readRDS(filename)

The first line will open the usual file open dialog box; you can select the file you want, and the name will be stored in the filename variable. The second line will use that name to open it.

Try to use \\ instead of /. That is what works for me.

If this is not working there is a chance that the rds file is destroyed so you need either to recreate it or if you have access to get a new copy then try with a new copy. I had the same issue once.

I hope that this helps
