All about Matrices:
#saving 12 numbers from 1 to 12 in a vector
v <- 1:12
v
#with out any options, vector got converted into 1 column table?(can we say table?)
matrix(v)
#first parameter is data, second parameter is no of rows
#if second parameter is ignored, default is length of data vector
matrix(v, 2)
#looks like doesn’t matter even the data is greater than required
matrix(v, 2, 4)
