Rmarkdown displaying results even when I use results = 'hide'

Question

I have a weird situation - and I apologize in advance, but this issue doesn't lend itself to a reproducible example. Here is the situation

Here is the skeleton of the problem

Chunk 1  
Chunk 2  
...  
Chunk N-1  

Then I have a chunk which is basically of the form:

{r chunkname, results = 'asis'}
f <- function(x){
y <- some computation on x
return(y)
}

T1 <- f(A)
T2 <- f(B)

According to the structure, nothing should get displayed, but when I knit the Rmarkdown file, both T1 and T2 appear. This is true even if I use results = 'hide'.

Now the weirder part. If I put the offending chunk in an Rmarkdown file by itself, it behaves as it should, and does not display T1 and T2.

The preceding chunks (Chunk1 - ChunkN-1) all run exactly as expected - no weird behaviors.

Last clue - not sure if it matters. The function in the offending chunk involves generating a table with gt.

I'm sorry - I realize there isn't a lot to go on here, but this is a chunk in the middle of several thousand lines of code - all of which run fine. And, when the offending code is on its own, it behaves.

Answer 1

I believe I have found an aswer to this problem. I left something seemingly innocuous out of my post.

The original code looked basically like:

{r chunkname, results = 'asis'}
f <- function(x){
y <- some computation on x
return(y)
}

T1 <- f(A)
T2 <- f(B)

save(T1)
save(T2)

Note that in my original post, I failed to include the "save(T1)" part. Well, it turned out that was the problem. If, instead of save(T1) I substitute temp <- save(T1), the issue disappears.

I don't understand why a save was causing something to be displayed. I also don't really understand what "assigning" the save action to the variable temp even means. But - it suppresses the output of the results to the kintted file.
