R Question

I need this:

`"X","Y",151,"X","Y",152,"X","Y",153,"X","Y",154,....."X","Y",334`

But I can only get this:

`names<-c("X","Y",seq(152,334,by=1))`

#"X","Y",151,152,153,154....334

Thanks

Answer

We can do

```
v1 <- 152:334
v2 <- rep(c("X", "Y", ""), length(v1))
v3 <- replace(v2, v2 == "", v1)
head(v3, 10)
#[1] "X" "Y" "152" "X" "Y" "153" "X" "Y" "154" "X"
tail(v3, 10)
# [1] "331" "X" "Y" "332" "X" "Y" "333" "X" "Y" "334"
```
