R是否有一个类似字符串的对象来公开文件API?

类似:

con <- textConnection("the_thing_i_am_writing_to", "w")

cat("Some text without a newline", file = con, append = TRUE)
cat("more text with two newlines\n\n", 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 在环境中为您创建)
