[R] which data structure to choose to keep multile objects?

I have a function called nnmf which takes in one matrix and returns two matrices. for example, > X [,1] [,2] [,3] [,4] [1,]147 10 [2,]258 11 [3,]369 12 > z=nnmf(X,2) > z$W [,1] [,2] [1,] 0.8645422 0.6643681 [2,] 1.7411863 0.5377504

[R] a bug with Student t-value??

Hello, every one, Using the qt() function in R, I got a different Student t-value with the Student t table. e.g. the return value of function qt(0.95,9) is 1.833, while in table it is 2.262. I do not know why the difference exists. I guess it may be a bug in R. -- Íõ»¯Èå ²©Ê¿Ñо¿Éú ±±¾©Ê¦·¶´óÑ
