Hi folks,

attr(z, "dim") <- c(10,10)
Error in attr(z, "dim") <- c(10, 10) :
dims [product 100] do not match the length of object [10]
Please help me to understand what mistake I committed? TIA
If you want a 10 x 10 matrix then:
zm <- matrix(z, 10, 10) # positional arguments to nrow and ncol.
If you were trying for something else, then please explain in plain
English rather than simply showing code that throws an error.
