R Question

I tried to write a loop that would, say, return me a vector of ten numeric entries. It went well, until i attempted to label each element of the output generated by the block with another line. The naming is supposed to produce each entry with their unique label characters: "number"[n] where n is number in the sequence of repeats which was used in the generation of numeric vector.

`multiples <- c()`

i <- c(1:10)

for (n in i) {

print (n * 10)

multiples[n] <- n * 10

names(multiples)[n] <- "number"[n]

}

multiples

The execution is successful but the result is not what i'm expecting. Is there a way to name the elements correctly using the same

`for`

Answer

I dont think you need loop here.

Are you trying to do this?

```
i <- 1:10
multiples <- i * 10
names(multiples) <- paste0("number", i)
multiples
#number1 number2 number3 number4 number5 number6 number7 number8
# 10 20 30 40 50 60 70 80
#number9 number10
# 90 100
```

If you want to stick to `for`

loop, you can

```
i <- c(1:10)
multiples <- numeric(10)
names(multiples) <- ""
for (n in i) {
multiples[n] <- n * 10
names(multiples)[n] <- paste0("number", n)
}
```
