Print character string without indices in R

Question

I have looked at the answers to Print list without line numbers in R and Prevent print() from outputting list indices in R, but neither seems to prevent R from printing a character string with indices are the left.

Input:

foo = "10 & 1.832171"    
print(foo, row.names=F, quote=F)

Output:

[1] 10 & 1.832171

Desired Output:

 10 & 1.832171

Is this possible at all?

Can you please explain the difference between your output and desired output? — Metrics, Nov 13 '13 at 00:50
@Metrics - Notice the `[1]` at the beginning of the code box displayed beneath "Output:" — Josh O'Brien, Nov 13 '13 at 00:53
Alternatives to print: `sprintf(fmt, str)`, or `message(...)`, or `cat(...)`, or stamp to file with `write(`, or `sink(`, then copy file to stdout with `cat(`. Also you can write bytes directly to stdout or stderr. Or call C functions like cout from R. — Eric Leschinski, Apr 11 '18 at 06:23

You have to manually include `\n` in the string if you want to use `cat` though. – naught101 Feb 06 '17 at 23:18
And for this - here is an example: https://stackoverflow.com/a/46198371/1089239 – Benny Dec 09 '17 at 22:54

`cat` doesn't seem to handle arrays... – not2qubit Sep 07 '18 at 11:33
@not2qubit Loop over your array and cat the individual values then – Dason Sep 07 '18 at 17:36

So a better solution is: `paste(string_vector, collapse = '\n') %>% cat()`. – not2qubit Sep 14 '18 at 05:43
I confirm that this also works in R Markdown in a situation where you're dealing with a single number of something. I used this to express the number of NA's (without the index) in certain data in an R Markdown report. Excellent, thank you! – jaggedjava Jan 09 '22 at 18:04
