Vector 请问这个词到底是什麽意思? 比方说以下这句 Character quantities & character vectors are used frequently in R 或是 along=vector , which if used must be the only parameter , and create a sequence 1 , 2 , ...... , length(vector) , or the empty sequence if the vector is empty (as it can be) 还有 Vectors are the most important type of object in R, but there are several others which we will meet more formally in later sections ----------------------------------------------------------------------------- 我感觉这应该是很重要的字 有很多意思在里面 可是我实在看不懂 请高人协助 -- --
