Re: [R] for cycle with uncontinuous numbers

You did not make "test" large enough to accept an index of 50 or any of the other numbers in x for that matter. On the first pass through that loop you to assigned to the 50 to the 50th element in test. If you wanted to assign 50 to the first element of test the you should look at the seq_a

Dear John, What I am trying to do is a genetic analysis and the "i" in my cycle are the numbers of markers I am testing. I know the code is not right, but what i wanted to do was to fill this 6 row matrix with the numbers in x So basically I wanted the cycle to loop only with the values on x (50,1

It is unclear exactly what you are trying to do. Since your 'test' matrix is only 6 rows in length, then when you extend it by trying to store into 50 for example, it will fill in the rest of the new values with NA. Can you explain what you think the code is supposed to do? It is doing exactly wh

Hi Tobias, thanks for the help, the code I am using is quite long, but basically what I tried to do was test <- matrix(0,6,1) x <- matrix( c(50,100,200,300,900,2343) ,ncol = 1) for (i in x){ test [i] <- (i) } but this code returns NA for all the elements which are not x Tobias Verbeke-2 w

Hi nice people, :-) I would like to do a for cycle but i wish it to assume only the numers 50, 100, 200, 300, 900 and 2343 I tried to do something like x <- c(50,100,200,300,900,2343) for (i in x){ #. } But it didn´t work If you would use a reproducible code example we could point out
