Re: [R] problem with win.metafile( ): traceback()

OK, I see the problem, and it should be fixed in the next release. Use 
trellis.device() till then. Thanks,

RE: [R] problem with win.metafile( ): traceback()

[Paul, David A]

In R1.8.0 for Windows, immediately after I 
execute win.metafile(...) and lset(...) I get the 
following values for .Device and .Devices:


> .Device
[1] "win.metafile://.../plot1.wmf"

> .Devices
[[1]]
[1] "null device"

[[2]]
[1] "win.metafile://.../plot1.wmf"


However, when I change to

> trellis.device(win.metafile, 
+   file = "//.../plot1.wmf", 
+   width = 8.5, height = 6.25)
>
> lset( list( background = list(col = "white")))

I get _no_ errors, and xyplot(...) creates the
appropriate windows metafile.

Could you check what the value of the .Device variable (and .Devices as
well) 
is at this point ? And not that it should matter, but what happens if you
use

trellis.device(win.metafile, file = "//.../plot1.wmf",
   width = 8.5, height = 6.25)

Subject: [R] problem with win.metafile( )


R1.8.0, Win2k:

When I paste the code


win.metafile(file = "//.../plot1.wmf",
width = 8.5, height = 6.25)
lset( list( background = list(col = "white")))  
xyplot( y ~ x | ID, data = Group1,
scales = list(alternating = FALSE),
ylim = c(.75,y.max),
panel = function(x, y, panel.number, ... )
{
panel.superpose(x = Group1$TIME, y = Group1$y,
subscripts = TRUE, groups =
Group1$ID,
type = 'l', col = gray(.6))
sup.sym <- trellis.par.get("superpose.symbol")
panel.xyplot(x, y, type = 'b', col = "black", 
lwd = 4, cex = 1.5, ...)
panel.loess(x = Group1$TIME, y = Group1$y, 
col = gray(.2), lwd = 3, lty = 5, span = 1/3)
}
)
dev.off()


into R1.8.0 I get the following messages:

.. 

> lset( list( background = list(col = "white")))
Error in get(x, envir, mode, inherits) : 
variable "win.metafile://.../plot1.wmf" was not found

.. 

> xyplot( .. )
Error in get(x, envir, mode, inherits) : 
variable "win.metafile://.../plot1.wmf" was not found
> 
> dev.off()
null device 
  1


If I change the first command in this script to

trellis.device(postscript, file = "//.../plot1.ps", color = TRUE)

I get no errors.  I also get no errors if I run the above script in R1.7.1.
Are there any known issues with win.metafile( ) in R1.8.0? Should I
reinstall?  Any help would be appreciated.
