Colleagues,
I encountered the following unexpected behavior today:
The following command yielded the expected result:
paste(c("TEXT1", "TEXT2"), collapse="|")
Result:
[1] "TEXT1|TEXT2"
However, abbreviating "collapse" by even one character:
paste(c("TEXT1", "TEXT2"), collaps="|")
yielded the following:
[1] "TEXT1 |" "TEXT2 |" >
My experience has been that one can abbreviate these options as long
as there is no ambiguity. For example, the "ignore.case" argument
for grep can be abbreviated to "ig" (shortening it to a single
character creates an ambiguity).
Is there something special about "collapse" that I am missing?
What you are missing is not special about 'collapse', but is rather a
feature shared by any argument after the "dots" in a function's
argument list.
