The same plot always shows up

[MikeRstudio]

Hi everybody

In my R Studio, I once plotted a certain function. I deleted R and R Studio and reinstalled it. I made a new Working Directory, cleared the session, looked out for unwanted things in the WD, inspected search paths, checked for auto loading scripts and searched for hidden files. If im plotting a function now, still the once plotted functions shows up. I don't know how this is possible and need help.

Thanks
Mike

Is there any chance you are loading an .Rdata file?

In RStudio try going to
Tools -> Global Options and de-selecting
Workplace
Restore .RData

[MikeRstudio]

No im really sorry I have tried too. But thanks for your response.

[jrkrideau]

Just guessing now but have a look at Resetting RStudio Desktop's State

[MikeRstudio]

Im not sure if I've fully understood this guide but I've tried and the problem is still there

Blast, I had some hope.

What does

sessionInfo()

give us?

Also can you post any code that you are running when you get that recurring plot?

A handy way to post output is to enclose it in within
```

```

[MikeRstudio]

Yeah surely
This is the used code, very simple...

hudoc <- hudoc_mb_Kopie
regression1 <- lm(hudoc$cost_exp~hudoc$npd_award)
summary(regression1)
plot(regression1)
sessionInfo()

here is the output of sessionInfo()

Btw the output given is this one

lm(formula = hudoc$cost_exp ~ hudoc$npd_award)

and I think the graph refers to a Shapiro Wilks test I once performed

Ive tried it with a simplified version and its still showing up

my_data <- data.frame(
  variable1= c(1,2,3,4,5),
  variable2= c(2,6,3,9,12)
)
regression <- lm(my_data)
plot(regression)

In the console it is

> my_data <- data.frame(
+   variable1= c(1,2,3,4,5),
+   variable2= c(2,6,3,9,12)
+ )
> regression <- lm(my_data)
> plot(regression)
Hit <Return> to see next plot: 
Hit <Return> to see next plot: 
Hit <Return> to see next plot: 
Hit <Return> to see next plot: 

and the output are four graphs

Im really sorry ive confused myself a lot its clear now I used the wrong function

[jrkrideau]

Okay, do you think the problem is resolved?

Nothing like laying out the problem for someone else to help you cure the problem.

[MikeRstudio]

No Than you so much for your effort, it was a complete fault of me, I don't know how I could get so confused. Unfortunately im a beginner.

Thank you very much

It's possible that the previously plotted function is still showing up in your R Studio environment because it's cached or stored in a temporary location. This can happen even if you've deleted R and R Studio and reinstalled them, as the caching mechanism may still retain the function data.
