I was just surprised by very un-intuitive behaviour of paste(), which appears
to collapse a one-column data frame or one-element list into a deparsed
expression, rather than producing the expected string. Can someone kindly
explain what's going on here?
reprex:
=======
list(s = c("xyz", "uvw"))
# s
# 1 xyz
# 2 uvw
paste(list(s = c("xyz", "uvw")), collapse = "")
# [1] "c(\"xyz\", \"uvw\")" # This is unexpected!
I would have expected:
# [1] "xyzuvw"
... which I do get with e.g.
paste(list(s = c("xyz", "uvw"))$s, collapse = "")
But what logic is there in returning a deparsed expression?
Thanks!
Boris
