instead. When you source() a script, auto-printing is not performed. This
is explained in the first paragraph of ?source, but not ?sink. If you want
to source() scripts and rely on their output (including sink()), you'll
need to print() results explicitly.
cat in R behaves similarly to cat in unix-alikes, sends text to a stdout.
Usually, that stdout would be a file, but usually in R it is the R Console.
I think it might also help to note the difference between cat and print:
x <- "test\n"
cat(x)
print(x)
produces

In the interactive mode, on the top level of execution, these commands
behave as if you had written
print(sink('data-summaries.txt'))

Bert,
If I used them in linux cat would display the file (as do more and less) and
print() would be replaced with lpr
Please consult ?cat . You might also spend

Please consult ?cat . You might also spend a bit of (more?) time with an R
tutorial or two as you seem confused about how assignment (<-) works. Or
maybe I'm confused about what is confusing you

Andrew,

I've read ?sink and several web pages about it but it's not working properly
when I have the commands in a script and source() them.
The file:
library(tidyverse)
library(lubridate)
sink('data-summaries.txt')
'corvalis discharge summary\n'
summary(cor_disc)
sd(cor_disc$cfs)
'-\n'
