Hi Abhilash,
>From ?example, under "arguments":
local: logical: if ‘TRUE’ evaluate locally, if ‘FALSE’ evaluate in
the workspace.
So all you need to do is:
> x <- 0
> example(mean, local=TRUE)
mean> x <- c(0:10, 50)
mean> xm <- mean(x)
mean> c(xm, mean(x, trim = 0.10))
[1] 8.75 5.50
mean> mean(USArrests, trim = 0.2)
Murder Assault UrbanPop Rape
7.42 167.60 66.20 20.16
> x
[1] 0
and nothing in your workspace is changed.
Best,
Ethan
