R Question

I am looking to make a function that takes a vector as input, does some simple arithmetic with the vector and call the new vector something which consists of a set string (say, "log.") plus the original vector name.

`d = c(1 2, 3)`

my.function <- function { x

x2 <- log(x)

...

I would like the function to return a vector called log.d (that is, not log.x or something set, but something dependent on the name of the vector input as x).

Answer

You can try next:

```
d = c(1, 2, 3)
my.function <- function(x){
x2 <- log(x)
arg_name <- deparse(substitute(x)) # Get argument name
var_name <- paste("log", arg_name, sep="_") # Construct the name
assign(var_name, x2, env=.GlobalEnv) # Assign values to variable
# variable will be created in .GlobalEnv
}
```
