Error Message when typing in command box

[MrArias]

I have downloaded the latest update and receive this message as a pop-up window

I am using RStudio as a teaching tool in Scotland for Higher Applications of Maths, so my coding knowledge is super minimal

Can anyone help, Error message below

Error in .rs.nullCoalesce(pref, "UTF-8") :
could not find function "...length"

Hi, welcome to the forum.

Ouch, that error looks a bit obscure though it seems you are running into a data encoding problem. Would you paste the output of

sessionInfo()

between
```

```
here.

We probably need to see the code you are using and a but of sample data. You should include all of your code as an error may only be obvious much later in the code execution.

Copy the code and paste it here between

```

```

A handy way to supply data is to use the dput() function. Do dput(mydata) where "mydata" is the name of your dataset. For really large datasets probably dput(head(mydata, 100)) will do. Paste the output between
```

```

Hi,

Thanks for helping.

Its every time I type something into the command window, so every few keystrokes

The initial code is, where I was setting the session working directory

setwd("C:/Users/my name/OneDrive - Glow Scotland/Lessons/2024-2025/Higher Apps/Data sets")

I did this via the drop down menus rather than typing it out

The result of SessionInfo() is below

I'm not sure if this helps you

Thanks for the details.
I am not sure how to interpret your locale information but I don't like the look of it. The LC_COLLATE=English_United Kingdom.1252 and LC_CTYPE=English_United Kingdom.1252 say that you are not using UTF-8 encoding which looks like the source of the problem.
Here is mine from a clean start.

You are running R version 3.3.0 (2016-05-03) which is well over 8.5 years and very, very out of date. You cannot run a lot of modern R packages on it.

I'd suggest upgrading to the most recent version of R which I believe is R version 4.4.2 and seeing what happens.

I am pretty sure that

setwd("C:/Users/my name/OneDrive - Glow Scotland/Lessons/2024-2025/Higher Apps/Data sets")

is not the correc way to access OneDRive but I have never used so cannot make any useful suggestions.
