maybe you can use the array function,like
>array(CO2,dim(CO2),list(rownames(CO2),colnames(CO2)))
and matrix is just a specif type of array,so maybe you can use as.matrix
>as.matrix(CO2)

the above tow,the CO2 is a data.frame which can use read.table to read in.

the third way is:use the scan the read the data and use array to change the data to array.
