## Get Column and Row Names -
   dimnames(X)
   
## Get Column / Row Names -
   colnames(X)
   rownames(X) 
   
## Try your own DIM - 
   DIM <- function(x) {c(NROW(x), NCOL(x))}
   DIM(X) 
   DIM(X[, 1])

## Try length / LENGTH - 
   length(X)
   length(X[, 1])
   LENGTH <- function(X) NROW(X)
   LENGTH(X)
   
## Columns / Rows - 
   ncol(X); NCOL(X)
   nrow(X); NROW(X)
