Question about example function
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 On Sun, Jun 5, 2011 at 11:13 AM, Abhilash Balakrishnan

Dear Sirs, I am exploring the R package and its documentation. ?I find there is the function example which runs examples from documentation pages. ?What confuses me is that running example interferes with the variables I have in my workspace.
x <- 0 example(mean) x
Now x is a vector of some values coming from the example. Am I using example in the wrong way? ?In situation like above running example apparently corrupts existing data, pollutes the workspace with variables I didn't create myself, and also leaves allocated data that consume memory. ?Is there a way to run example to avoid this? ?I tried the following:
x <- 0 local(example(mean)) x
Still x is corrupted with example data. Thank you for support. Abhilash B. ? ? ? ?[[alternative HTML version deleted]]
