The result of the function is a list giving not only the efficiency factors as the first component, but also the block and variety canonical contrasts, since sometimes these give additional useful qualitative information. 2 Dropping all names in a printed array For printing purposes with large matrices or arrays, it is often useful to print them in close block form without the array names or numbers. Removing the dimnames attribute will not achieve this effect, but rather the array must be given a dimnames attribute consisting of empty strings.
Are factors. The following formulae on the left side below specify statistical models as described on the right. y~x y~1+x Both imply the same simple linear regression model of y on x. The first has an implicit intercept term, and the second an explicit one. y~0+x y ~ -1 + x y ~ x - 1 Simple linear regression of y on x through the origin (that is, without an intercept term). log(y) ~ x1 + x2 Multiple regression of the transformed variable, log(y), on x1 and x2 (with an implicit intercept term).
