Does R have a string-like object that exposes a file API?
It's sometimes convenient to write a string to an in-memory object and then pass that object to functions in place of a file handle. In Python, there's StringIO. Does R have something equivalent?

Something like:
con <- textConnection("the_thing_i_am_writing_to", "w")
cat("Some text without a newline", file = con, append = TRUE)
cat("more text with two newlinesnn", file = con, append = TRUE)
writeLines(rownames(mtcars), con = con)
cat("this is after the car names", file = con, append = TRUE)
close(con)
str(the_thing_i_am_writing_to)
## chr [1:35] "Some text without a newlinemore text with two newlines" "" "Mazda RX4" "Mazda RX4 Wag" ...
(the_thing_i_am_writing_to
gets created in the environment for you)
Thanks, I did not know abouttextConnection

👍 def view the help on it. it has anencoding
parameter that may be needed if you're dealing with various locales or want to ensure UTF-8.
