What cause format change when copy and paste in rstudio?

Question

#sample select
sample_frac(mydata,n%)#random select n% sample

##############data review####

Just copy above code into rstudio script, you will find 2 more tab added to the last line.
What cause it?

Answer 1

Edit

As mentioned by @Jay in the comments, the n% in the command is treated as a function and since it is not complete it indents the next line.

To further confirm, try with df %in% in the script or df >%> and hit enter to see the cursor goes to the next line with an indent.

To avoid that just complete the function there.

sample_frac(mydata,n)

OR

sample_frac(mydata, n %% somenumber)

whatever you are trying to do and it should be fine.

Original Answer

It did add 2 tab spaces in the code when pasting in the RStudio script. I tried to paste the same text in my notes, Pycharm editor but it did not add any extra tabs there. So it was sure that this is a RStudio issue.

It turns out it is the indentation settings in RStudio which is responsible for this. To change that:

Go to Tools -> Global Options. Click on the Code option on the left. You'll see this :

Uncheck Auto-indent code after paste

and click on OK.

Now try to paste the same text. Should be resolved.
