Get only the structure (row names & column names) of data set in R

Consider a data frame with row names and column names:

> data <- data.frame(a=1:3,b=2:4,c=3:5,row.names=c("x","y","z"))
> data
  a b c
x 1 2 3
y 2 3 4
z 3 4 5

I just want to display the row names and column names of data like:

  a b c
x   
y   
z

I want a data.frame as output.

If you want to see the column names in your dataset just use this

print(names(dataset_name))

For its structure,

str(dataset_name)

Perhaps you need

data[] <- ''
data
#  a b c
#x      
#y      
#z

If we need only the names, then dimnames is an option which return the row names and column names in a list.

 dimnames(data)
 #[[1]]
 #[1] "x" "y" "z"

 #[[2]]
 #[1] "a" "b" "c"

Or may be

m1 <- matrix("", ncol = ncol(data), nrow = nrow(data), 
        dimnames = list(rownames(data), colnames(data)) )
