Dear R-Helper,
(There are quite a few of us.)
I want to know how I get a list work which I saved in RData file. For example,
I don't understand that at all, but it looks as if you want to save an unevaluated call, in which case see ?quote and use something like xyadd <- quote(test.xy(x=2, y=3)) load and saving has nothing to do with this: it doesn't change the meaning of objects in the workspace.
test.xy <- function(x,y) {
+ xy <- x+y + xy + }
xyadd <- test.xy(x=2, y=3) xyadd
[1] 5
x1 <- c(2,43,60,8) y1 <- c(91,7,5,30) xyadd1 <- test.xy(x=x1, y=y1) xyadd1
[1] 93 50 65 38
save(list = ls(all=TRUE), file = "testxy.RData")
rm(list=ls(all=TRUE))
load("C:/R/useR/testxy.RData")
ls()
[1] "test.xy" "x1" "xyadd" "xyadd1" "y1"
ls.str(pat="xyadd")
xyadd : num 5 xyadd1 : num [1:4] 93 50 65 38
When I run, I know the result like above
xyadd
[1] 5
xyadd1
[1] 93 50 65 38
what I want to know, is there any function to make the result like:
xyadd
test.xy(x=2, y=3)
and
xyadd1
test.xy(x=x1, y=y1)
