In the help of strsplit one can read
split character vector (or object which can be coerced to such) containing regular expression<http://127.0.0.1:39783/help/library/base/help/regular%20expression>(s) (unless fixed = TRUE) to use for splitting. If empty matches occur, in particular if split has length 0, x is split into single characters. Ifsplit has length greater than 1, it is re-cycled along x.
Taking into account that split is said to be a vector (not a length 1 vector) and the last claim above, I would expect that the output of
strsplit("3:4", split = c(",",":"), fixed = TRUE)
was the same than the output of
strsplit("3:4", split = c(":"), fixed = TRUE)
that is, splitting by "," (without effect in this example) and also by ":"
 "3" "4"
But, instead, I get
Am I wrongly understanding the help? Is it an expected output?
I tried with R 3.6.1 for Windows (10).
