[R] outer to vectors

Hi all, Having a matrix A formed by n vectors as columns. Is there anything to calculate a determined function to all combination of vectors? For example imagine A matrix is compose by vectors a, b and c. And the function to perform is correlation, so I would like to obtain cor(a, b), cor(a,

Re: [R] change individual label colours in a cluster plot?

Hi, If you have a variable, that defines what you want to differentiate (sociology, economics etc.) then you can add color depending on the value of that variable. You will have to convert it to numeric if it is not. An example would be plot( iris[ , 1 ], iris[ , 2], col = iris[ , 3 ] ) Re

Re: [R] t-test

Hi, If you mean if the t.test is done as if the samples where paired, the answer is yes if you write argument paired = TRUE; and the pairs are done in order, that is 1º with 1º, 2º with 2º, etc. As you wrote, (paired = FALSE) the t.test is unpaired, and the order of elements in the vectors a

Hi all, I have two vectors like this: x <- c( "Y", "H", NA, NA ) y <- c( NA, "H", NA, "B" ) And would like to make one vector with the common elements, and the element available only in one of the vectors. res <- c( "Y", "H", NA, "B" ) Thanks, Patricia > From:
