Subtracting a matrix 1x28 from a scalar
Afternoon- I am trying to subtract a matrix, basically a vector of 28 values, each by the same number to account for differences in regression fitting. I am taking the 1x28 and minus it by the mean value of the matrix, each number. The result I receive is a 1X29 matrix. Does anyone know why the result has an extra value? > lffeb_march [1] 6.588926 7.663877 6.917706 6.824374 7.029973 6.549651 6.517671 6.070738 5.916202 [10] 6.993933 6.091310 7.313220 5.135798 6.762730 6.381816 7.999679 6.851185 5.799093 [19] 7.774856 6.956545 8.218787 8.218787 7.549609...
