我学习vue.js，并用HTML和CSS创建了一种基本形式：

这就是我在R中这样做的方式.
array = (1:100)
i = 3
sel <- !as.logical(array %% i)
print(sel)
结果如下:
[1] FALSE FALSE TRUE FALSE FALSE TRUE FALSE FALSE TRUE FALSE FALSE TRUE FALSE FALSE
[15] TRUE FALSE FALSE TRUE FALSE FALSE TRUE FALSE FALSE TRUE FALSE FALSE TRUE FALSE
[29] FALSE TRUE FALSE FALSE TRUE FALSE FALSE TRUE FALSE FALSE TRUE FALSE FALSE TRUE
