importing data and installing packages??

[novice97]

hello guys, im a newbie (more or less) at programming with R, and I havent used Rstudio since 2019, so now when I try to install some packages, I get a message saying "Warning message:
the 'rlang' package was compiled with R 3.6.3"
so I thought maybe this means I have an old version or smtg, so I installed the latest version and still no use, I still get this msg. And this poses problems when I try to import data. at first I used the rio package and it worked once and I was able to use the import function, but after few days, I retried it and it wont work. this is what it says"Error: package or namespace load failed for 'rio' in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]) :
package 'rlang' 0.4.11 is already loaded, but >= 1.0.0 is required"
now im just trying to import a csv the traditional way but that also doesnt work, this is what I get :

setwd("C:/Users/user/Documents/targetTS/")
Error in setwd("C:/Users/user/Documents/targetTS/") :
cannot change working directory
data <- read.csv("targetTS.csv")
Error in file(file, "rt") : cannot open the connection
In addition: Warning message:
In file(file, "rt") :
cannot open file 'targetTS.csv': No such file or directory.
Please help Im really desperate rn, if my supervisor knows im still stuck at this step I would be in big trouble. Thanks

package 'rlang' 0.4.11 is already loaded, but >= 1.0.0 is required"

Run install.packages("rlang") and then read the error message, it says it cannot find C:/Users/user/Documents/targetTS/ and therefore cannot open targetTS.csv, so check that you got those directories right or even better... Run your project using projects in RStudio

Hello, I am indeed working with Rstudio, and I checked the directory from the file's properties so normally it should be correct and I tried reversing these "/" but it still didnt work.

Try to play around with list.files() and put in your path gradually to see where it fails?

[nirgrahamuk]

you might try file.choose()

[novice97]

list.files("C:/Users/user/Documents/targetTS/")
character(0)
this is what I get when I try list.files, im not sure if thats the right way to use it.
I also tried file.choose and I select the file I need, it gives me the directory or path of the file but what should I do next?
file.choose("targetTS.csv")
[1] "C:\Users\user\Documents\targetTS.csv"

[nirgrahamuk]

the result of file.choose shows you were incorrect that there was a folder 'targetTS' involved.
rather your folder path is C:\Users\user\Documents\ and the filename is targetTS.csv
you wont be able to setwd() on a folder path that doesnt exist ; such as targetTS.
so either, you setwd() on your documents path. or you make a folder called targetTS and move targetTS.csv into it.

I created a folder and put my data file in it and it finally worked. Thanks you for your help
Thanks Leon and nirgrahamuk.

I have a problem installing some packages and I know the problem is on my end.
I'm on a Mac, Ventura 13.3.1 OS, latest versions of R and RStudio.

Here is my code (quite simple):

remotes::install_github("stan-dev/cmdstanr")
devtools::install_github("rmcelreath/rethinking")

here is the error message:

I uninstalled and reinstalled R this morning with same result. I tried installing on R (not RStudio) with same result.

Any ideas?

Many thanks.
