Hi , What I did was similar, install R, R(D)COM server an RExcelInstaller package. Then just write installRExcel() in the console. And it works. Something you should know is that there is a specific mailing list for RCOM topic in here:

[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: [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

[R] Create a vector from matrix.

Hi all, I am trying to create a vector with the information contained in a determined matrix. Let me explain myself. I have a vector like this: q - c(a,a,c,b,d,d,a,e,b,a) And a matrix like: s1 - c(a,b,c,d,e,f,g,h,i,j) e - c(A,B,C,D,E,F,G,H,I,J) s - cbind( e,

[R] Merge two vectors into one.

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:

Re: [R] Merge two vectors into one.

Is position important? The vectors always have the same length? They always have the same entry if both are not NA? If yes, yes and yes, then res - ifelse( is.na(x), y, x) does what you want. Otherwise please explain better what you want. Gabor On Wed, Jan 28, 2009 at 3:54 PM, patricia garcía

Hi everyone, Is there any function to standardize a matrix. For sure it must, but i can't find it. For standardize, i just mean, to make the mean as zero and standard deviation as one.It is also call z-score. Thanks in advance
