R：在同一阵列中存储不同大小的矩阵？

Question

I am wondering if it is possible to store different size of matrices in same array. I'm organizing monthly data for temperature, and I encounter with matrices are different each month. For example, February has only 28 days but January has 31 days.

Data I'm dealing with contains 8 types of data, such as temperatures. Each day in a month, 144 data is collected, so total number of data in January is 4464, April is 4320 (30days).

I sat my array: Brianna <- array(0, dim=c(4464, 8))

But this will not work. This works only for 31-day-month, January, March, May, etc. Does anyone have suggestion to solve this problem? Or do I have to store each month in different array?

Thank you for your help.

You can have a list of matrices with different dimensions:

x <- matrix(1:12, 3)
y <- matrix(1:20,4)
list(x,y)
