Hello I have some kind of problem with R. I want to do a pca (I work on R and ade4 library) but R doesn't wan to realize my pca because of my data: I have some binary variable (presence/absence of birds, hole, vegetals...) and metric variable (cliff 's size...) and each time I have an error message because of the mix of the 2 type of variable. So, what can I do? Famille SALMON

I know this question is very simple, but I am not figure it out I have the data frame:   test<- data.frame(year=c(2000,2000,2001,2001),x=c(54,41,90,15), y=c(29,2,92,22), z=c(26,68,46,51)) test   year    x   y   z 1 2000 54 29 26 2 2000 41  2  68 3 2001 90 92 46 4 2001 15 22 51   I want to sum the vectors x, y and z within each year (2000
