[R] plot via xyplot not being saved
Hi everyone, it's been a while I've been trying to save a plot created via lattice:::xyplot if I have a file tst.R with the following code: y - rnorm(100) x - rnorm(100) z - sample(letters[1:4], 100, rep=T) library(lattice) bitmap(tst.png) xyplot(y~x|z) dev.off() and I source it, I get the tst.png file, which is a blank page. If I copy and paste instead, I get the correct plot. Any suggestion?

Re: [R] plot via xyplot not being saved
So, if those statements are inside a function, I have to make my
function to have an 'echo' argument/functionality? eg.:
## begin test.R
test - function(n){
y - rnorm(n)
x - rnorm(n)
z - sample(letters[1:4], n, rep=T)
library(lattice)
bitmap(tst.png)
xyplot(y~x|z)
dev.off()
}
test(100)
## end test.R
source(test.R, echo=T)
also fails in this case...
thanks a lot,

Use
source(..., echo = TRUE)

Yes. The following will produce some output (the values of x + y and x
- y) if you type it out at the R prompt:
x - rnorm(10)
y - rnorm(10)
x + y
x - y
If you put that in a file and source it, nothing will get printed,
unless you have echo=TRUE. If you define
test - function(){
x - rnorm(10)
y - rnorm(10)
x + y
x - y
}
calling test() at the R prompt will only print x - y and not x + y, and so on.
This is all standard R behaviour. If you want something to be printed
irrespective of context, use print(), e.g.
print(x + y)
or
print(xyplot(y~x|z))
This is also mentioned in the R FAQ.

Re: [R] plot via xyplot not being saved
Thank you Deepayan,
I understand the behavior of not printing out the results inside the
functions.
What I didn't know was that for xyplot() saving the plot actually
meant save the result I see, which does not happen with plot(), in
which case my function test() works just fine if I replaced xyplot()
by plot().
Thank you very much,
