如何创建一个空的 R 向量来添加新项目 [英] How to create an empty R vector to add new items
问题描述
我想在 Python 中使用 R,正如模块 Rpy2 提供的那样.我注意到 R 有非常方便的 []
操作,您可以通过它提取特定的列或行.怎么用Python脚本实现这样的功能?
I want to use R in Python, as provided by the module Rpy2. I notice that R has very convenient []
operations by which you can extract the specific columns or lines. How could I achieve such a function by Python scripts?
我的想法是创建一个 R 向量并将那些想要的元素添加到这个向量中,以便最终的向量与 R 中的相同.我创建了一个 seq()
,但似乎它有一个初始数字 1,所以最终结果总是从数字 1 开始,这不是我想要的.那么,有没有更好的方法来做到这一点?
My idea is to create an R vector and add those wanted elements into this vector so that the final vector is the same as that in R. I created a seq()
, but it seems that it has an initial digit 1, so the final result would always start with the digit 1, which is not what I want. So, is there a better way to do this?
推荐答案
vec <- vector()
另见矢量帮助
?vector
