Subject: [R] a little question about R
Hello,sir: Here's a little question about R which needs your
help.Thanks in advance.
If I wanna make a sequence just like a,b,c,d (In other
words,a vector consists of 4 characters :a,b,c,d ).How can I
do it in a shortcut manner? Yes,I can do it as following:
c("a","b","c","d") and the result is:[1] "a" "b" "c" "d".
But I remember there's a shortcut manner to do the same
thing,something like c("a":"d").But the system said:"Error in
"a":"d" : NA/NaN argument" So I wonder the correct method to
do it(I remember the expression is very similar with
c("a":"d")). Thanks from the bottom of my heart. My best regards!
