Using vector type in R data frame

Question

The R language doesn't allow vectors to be variables. Why it is missing the feature? it would be nice my data frame with following features have something like this:

    X1         X2     
1.  [1,2,3]   [2,3,4] <br>
2.  ....         ....

I tried df <- as.data.frame(c(1,2,3),c(1,2,3)) but keep getting 3 rows created with numeric type instead I want a single row with vector type

Answer 1

Use an array:

array(rbind(1:3, 2:4), dim = c(1, 2, 3))
#, , 1
#
#     [,1] [,2]
#[1,]    1    2
#
#, , 2
#
#     [,1] [,2]
#[1,]    2    3
#
#, , 3
#
#     [,1] [,2]
#[1,]    3    4

Answer 2

R不允许使用行数据类型，您可以使用列数据类型。每列可以是单独的数据类型向量。你不是在想'R'的方式。正如你所说的那样，这就是R的优势。你可以使用前一个答案中建议的数组，如果你真的想要遵循你的想法。或者只是试着看看你如何在'R'中做你想做的事。而不是试图将你已知的语言强加给R。
