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.
