dear r-users,
i have got a problem which i am trying to solve:
i have got the following commands:
Mymatrix <- matrix(1:9,ncol=3)
Z <-
list
("V1
"=c("a","",""),"V2"=c("b","",""),"V3"=c("c","",""),"V4"=c("d","",""))
rbind(Mymatrix, t(as.data.frame(Z))) The next method could be used if you had more lists: do.call(rbind, list(Mymatrix, t(as.data.frame(Z))))
Mymatrix <- rbind(Mymatrix,Z[[1]],Z[[2]],Z[[3]],Z[[4]]) now this is working, but i would like to substitute Z[[1]],Z[[2]],Z[[3]],Z[[4]] for a command with which i could also use another list with a different number of elements, e.g. 5 or 6 elements.
